7 W laser diode end-pumped Nd:YVO4 passively mode-locking laser with a semiconductor saturable absorber mirror

Abstract

A powerful and stable LD end pumped Nd:YVO 4 passively mode locking oscillator by SESAM was demonstrated. At the pumping power of 30 W, 7 W output was obtained with repetition rate of 79.5 MHz and pulse duration of 15 ps. The beam quality factors M 2 were measured to be 1.30 and 1.33, respectively.

Diode lasers: From laboratory to industry

“…For the empowerment of existing and new applications, a long-standing and ongoing effort is continued for investigating novel gain hosts [92]. 669 nm CW intracavity frequency doubled Nd:YAG-KTiOPO 4 red laser [93], 7 W laser diode end-pumped Nd:YVO 4 passively mode-locking laser [94], intracavity frequency doubled Nd:Y 0.36 Gd 0.64 VO 4 -GdCa 4 O(BO 3 ) 3 green laser at 532 nm [95], and diode-pumped tunable single frequency Tm:YAG laser with two etalons [96] were among few DPSSLs that have recently appeared on the scene.…”
