Passion Extreme Light

Nobel Laureate Gérard Mourou, École Polytechnique (France)

Extreme-light laser is a universal source providing a vast range of high energy radiations and particles along with the highest field, highest pressure, temperature and acceleration. It offers the possibility to shed light on some of the remaining unanswered questions in fundamental physics like the genesis of cosmic rays with energies in excess of 1020 eV or the loss of information in black-holes. Using wake-field acceleration some of these fundamental questions could be studied in the laboratory. In addition extreme-light makes possible the study of the structure of vacuum and particle production in "empty" space which is one of the field’s ultimate goal, reaching into the fundamental QED and possibly QCD regimes.
Looking beyond today’s intensity horizon, we will introduce a new concept that could make possible the generation of attosecond-zeptosecond high energy coherent pulse, de facto in x-ray domain, opening at the Schwinger level, the zettawatt, and PeV regime; the next chapter of laser-matter interaction.

Gérard Mourou is Professor Haut-Collège at the École polytechnique. He is also the A.D. Moore Distinguished University Emeritus Professor of the University of Michigan. He received his undergraduate education at the University of Grenoble (1967) and his Ph.D. from University Paris VI in 1973. He has made numerous contributions to the field of ultrafast lasers, high-speed electronics, and medicine. But, his most important invention, demonstrated with his student Donna Strickland while at the University of Rochester (N.Y.), is the laser amplification technique known as Chirped Pulse Amplification (CPA), universally used today. CPA revolutionized the field of optics, opening new branches like attosecond pulse generation, Nonlinear QED, compact particle accelerators. It extended the field of optics to nuclear and particle physics. In 2005, Prof. Mourou proposed a new infrastructure ; the Extreme Light Infrastructure (ELI), which is distributed over three pillars located in Czech Republic, Romania, and Hungary. Prof. Mourou also pioneered the field of femtosecond ophthalmology that relies on a CPA femtosecond laser for precise myopia corrections and corneal transplants. Over a million such procedures are now performed annually. Prof. Mourou is member of the U.S. National Academy of Engineering, and a foreign member of the Russian Science Academy, the Austrian Sciences Academy, and the Lombardy Academy for Sciences and Letters. He is Chevalier de la Légion d’honneur and was awarded the 2018 Nobel Prize in Physics with his former student Donna Strickland.

SPIE 2020 Gold Medal Winner:

Dual Comb Modelocking with Spectroscopy and Lidar Applications

Ursula Keller, ETH Zurich (Switzerland)

A fully stabilized optical frequency comb provides equally spaced frequencies for a precise ruler in optical frequency metrology. This talk will review recent progress in dual-comb generation from diode pumped solid-state and vertical emitting semiconductor lasers. In dual-comb modelocked operation, the initially unpolarized beam is split with an intracavity birefringent crystal. A mode-locked integrated external-cavity surface-emitting laser (MIXSEL) integrates both the gain and the saturable absorber layer within the same semiconductor wafer which simplifies the laser geometry to a linear straight cavity with excellent noise performance. A dual-comb gigahertz optically pumped MIXSEL has been used for molecular spectroscopy and lidar applications without the need of any additional stabilization. More recently a dual-comb diode-pumped Yb:CaF2 laser has been demonstrated at 140 MHz. For lidar applications we compare both lasers demonstrating micron precision over a potential ambiguity range of multi-kilometers and multi-kilohertz update rates.

Ursula Keller has been a tenured professor of physics at ETH Zurich since 1993 (, and serves as a director of the Swiss research program NCCR MUST in ultrafast science since 2010 ( She received a “Diplom” at ETH Zurich in 1984, a Ph.D. at Stanford University USA in 1989, was a Member of Technical Staff at Bell Labs USA 1989 to 1993.

Progress of Photonic Crystal Surface-Emitting Lasers

Susumu Noda, Kyoto Univ. (Japan)

Photonic crystal surface-emitting lasers (PCSELs) are an unprecedented type of semiconductor laser that can achieve single longitudinal- and lateral-mode oscillation even over areas of millimeters in diameter. Their brightness, defined as power per unit area per unit solid angle, is expected to be increased up to the range of 1~10GWcm-2sr-1, which is comparable to those of gas lasers and fiber lasers. Also, PCSELs have additional functions, including the generation of beams with various patterns and polarizations, and they can even achieve electric two-dimensional beam scanning. Material systems for PCSELs are currently being expanded to not only InGaAs/GaAs (900-1000nm), but also InGaAsP/InP (1.3-1.55um) and even InGaN/GaN (400-530nm). LiDAR is discussed as one example of the applications of PCSELs. PCSELs will become a key light source in the forthcoming ultra-smart Society 5.0, which includes smart mobility and smart processing.

Professor Susumu Noda received B.S., M.S., and Ph.D. degrees from Kyoto University, Kyoto, Japan, in 1982, 1984, and 1991, respectively, all in electronics.

Unifying the Optoelectronic Spectrum at the Chip Scale

Kerry Vahala, Caltech (USA)

Electronics and photonics have long had a complementary coexistence across multiple application areas. Nonetheless, an ideal partnership of these two realms was made challenging in large part by the enormous frequencies of lightwaves. About two decades ago, this limitation was overcome with the invention of the laser frequency comb. Combs provide a coherent link between electronics and photonics, and because the link is bidirectional, performance attributes previously unique to each can now be shared. Their implementation has been transformative for time keeping, frequency metrology, precision spectroscopy, microwave-generation, ranging and other technologies. More recently still, high-Q nonlinear optical microresonators, have enabled chip-scale frequency combs. I will review efforts to fully integrate comb systems around these new ‘microcombs,’ along with the physical principles of the devices themselves. Finally, I will consider the revolutionary impact this chip-scale unification of the optoelectronic spectrum can have on photonic instrumentation and consumer products.

Kerry Vahala is the Jenkins Professor and Professor of Applied Physics at Caltech. He is known for his studies of devices called optical microcavities and their application to a wide range of subjects including miniature frequency and time systems, microwave sources, parametric oscillators, astrocombs and gyroscopes. Vahala also made early contributions to the subject of cavity optomechanics and demonstrations of chip-based devices to cavity QED phenomena. He is a member of the National Academy of Engineering and a fellow of the IEEE and the OSA. Vahala received an Alexander von Humboldt Award for his work on ultra-high-Q optical microcavities, a NASA achievement award for application of frequency combs to exoplanet detection, and the OSA Paul F. Forman Team Engineering Excellence Award for a 2-photon optical clock. He was also involved in the early effort to develop quantum-well lasers for optical communications and received the IEEE Sarnoff Award for his research on quantum-well laser dynamics.

Ultimate Two-dimensional Media and Evolution of Advanced Immersive Sensory Media

Kohji Mitani, Japan Broadcasting Corporation (NHK) (Japan) and Science & Technology Research Laboratories (STRL) (Japan)

Japan Broadcasting Corporation (NHK) Science & Technology Research Laboratories (STRL) has long been consistently opening up new horizons for broadcasting. Its recent R&D on 8K ultra-high-definition television, the ultimate two-dimensional television, came to fruition as a regular satellite broadcasting service in Japan in December 2018, with 8K gradually penetrating media and other industries globally. The 8K specifications were determined based on psychophysical experiments to effectively produce an immersive and realistic experience with a two-dimensional screen. STRL is continuing to enhance user experiences. Aside from two-dimensional displays, today there are media devices such as head-mounted displays, augmented reality glasses, three-dimensional displays, and haptic devices. STRL is researching these devices to enhance their performance from the perspective of visual psychology and cognitive science. It is also developing three-dimensional information processing technologies and artificial intelligence aiming for new content presentations with new immersive devices. Conveying sensations other than sight and sound will create innovative sensory experiences that provide unprecedented immersion. A new media scheme that utilizes various delivery platforms such as broadcasting, the internet, and 5G is also being studied to produce new viewing experiences.

Kohji Mitani joined Japan Broadcasting Corporation (NHK) in 1987. He has been helping develop 8K ultra-high-definition television at Science & Technology Research Laboratories (STRL) since 1995. In particular, he was in charge of developing 8K camera systems. He moved to NHK headquarters in 2010 and worked in the Engineering Administration Department to develop a practical 8K production and broadcasting system. He was appointed Deputy Director of STRL in 2016, and he was appointed to his current position, Director of STRL, in 2018. He is currently promoting research and development for future media, Diverse Vision. He received a Ph.D. from Kyoto University in 1999 and a fellow grade of membership from the SMPTE (Society of Motion Picture & Television Engineers) in 2010.
