7.6-W diode-pumped femtosecond Yb:KGW laser

Abstract

We have demonstrated a high power diode-pumped mode-locked femtosecond Yb:KGW laser with semiconductor saturable absorber mirror (SESAM). By using an output coupler with 10% transmittance, the laser delivered 160-fs pulses with average output power of 7.6 W at a repetition rate of 78 MHz, corresponding to pulse energy of 97 nJ and peak power of 606 kW.

“…[8][9][10][11][12][13][14][15] Recently, the development of high power Yb-doped all-solid-state laser and fiber amplifier have overcome the limitation of Ti:sapphire pump technology. [16][17][18] The wavelengths of Yb-doped laser pumped OPOs are generally longer than 1300 nm, while the OPOs pumped by green laser could cover visible (VIS)-near infrared pulses simultaneously, [19] and the short wavelength of idler pulses can cover the spectrum over 1100 nm-1300 nm.…”
