250 fs, 150 mW laser with tunable pulse repetition rate in GHz-regime

25 January 2022 • 11:00 AM - 11:20 AM PST | Room 204 (Level 2 South)

Abstract

We report a compact ultrafast solid-state laser source with a pulse repetition rate tunable in the range of 0.5 – 1.3 GHz. The optical cavity design allows a user to vary the repetition rate only by moving the mirrors. The Yb:KYW crystal-based laser emits 250 fs pulses at a central wavelength of 1040nm and the SESAM modelocking enables self-starting. An average power up to 150 mW is achieved using a stabilized single mode pump source at 981 nm, emitting up to 800 mW. In continuous wave mode, up to 270 mW were measured with an optical-to-optical efficiency of 33%.
