Ultrafast Laser Science

State-of-the-art laser performance enabled by cryogenic-cooling

Science and technology are inextricably linked and continue to drive each other. Ultrafast lasers have revolutionized our understanding of how molecules and materials work and how charges, spins, phonons and photons interact dynamically. In past research, KMLabs designed Ti:sapphire lasers that operate at the limits of pulse duration and stability, with adjustable pulse durations from 7 fs on up. These lasers are now a standard fixture in thousands of laboratories worldwide. More recently, we developed tabletop high peak-power, high average-power lasers with unprecedented short pulse duration, spanning the UV to the mid-infrared regions of the spectrum.

Our latest laser science projects involve developing mid-infrared lasers that are optimized for driving bright soft X-ray high harmonic beams, in a simple and compact setup that is optimized for applications. These tabletop-scale lasers are based on cryogenic-cooling of the amplifier crystal. This new laser system will make it possible to extend many successful applications of high harmonic generation from the EUV to the soft X-ray region of the spectrum. We are also continually developing new laser designs, diagnostics, and optical elements at KMLabs.
