Optical Engineering • Open AccessSpecial Section Guest Editorial: Ultrashort Pulsed Laser and Applications Engineering
Forty years after the publication from Shank and Ippen on the generation of subpicosecond laser pulses we are witnessing an explosion in the number of applications for ultrashort pulsed lasers (USPL).1 While some technologies are invented and applied in industry without delay, there has been a significant delay in the deployment of femtosecond lasers. Ultrashort pulsed lasers used to require a laboratory environment and in many cases included flowing laser dye solutions that made them extremely impractical. The development of chirped pulse amplification for solid state and fiber lasers2,3 has changed the landscape and has made available intense USPL sources that can be operated outside the laboratory. This in turn has opened numerous applications in the materials processing and medical devices markets. In this special section we present a collection of papers that is representative of some of the advancements and applications in USPL design and applications.
