High efficient mode-locked Tm:YAP laser emitting at 1938 nm by SESAM

Abstract We report a passively mode-locked (ML) Tm:YAP laser pumped by an 790 nm AlGaAs diode. With a semiconductor saturable absorber mirror (SESAM) as mode-locker, stable ML pulses is generated with pulse width of 1.89 ps, repetition rate of 97 MHz, and central wavelength of 1938 nm. The highest ML output power of 710 mW was obtained, to the best of our knowledge, this is the highest output power of SESAM based, Tm ion doped crystalline ML lasers.
