Laser Resonators, Microresonators, and Beam Control XXVII

Innovation in laser resonator and beam profile design is key to solving various scientific and technological problems, from improving the fundamental performance of laser systems to enabling new laser-based applications. Advancement can take many forms including controlling the shape of the laser beam, improving the cavity performance, and creating new functionality. Given the cross-cutting nature of lasers, advances in laser systems rapidly leads to new application areas. In our conference sessions, we represent the versatility of today’s engineering toolbox, capable of delivering on-demand solution for virtually every possible laser specification and application need.

Classical approaches to cavity design and beam shaping have been recently amended with vast new opportunities stemming from achievements of material science, micro- and nano-fabrication, metrology, and instrumentation. Emerging technical and industrial needs stimulate new methods of beam shaping and control for optimized energy delivery in fabrication, communication, and sensing. Recent advances in transparent materials and coatings feed the new generation of high-finesse reference cavities for frequency stabilization.

Maturing field of optical microresonators continues to expand the chip-level photonics toolkit, including optical frequency combs, frequency metrology, signal processing, quantum communication and computing, high-rate data communication, biochemical, inertial, range sensors (LiDARs), and other emerging areas. Fusion of discrete and distributed approaches, development of metamaterials and methods of inverse design optimization improve transparency of planar photonics and interfaces with fiber networks and free space beams.
