880 nm LD pumped passive mode-locked TEM_(00) Nd:YVO_4 laser based on SESAM

摘要

We report on an 880 nm LD pumped passive mode-locked TEM_(00) Nd:YVO_4 laser based on a semiconductor saturable absorber mirror (SESAM) for the first time. When the incident pump power was 16 W, 4.76 W average output power of continuous-wave mode-locked laser with an optical-to-optical conversion efficiency of 30% was achieved. The repetition rate of mode-locked pulse was 80 MHz with 25 ps pulse width. The maximum pulse energy and peak power were 60 nJ and 2.4 kW, respectively.
