摘要：We report a passively continuous-wave mode-locked (CWML) Nd:Gd0.19Y0.81VO4laser oscillating at 1342.3 nm for the first time in this paper. Stable mode-locked pulse cluster with a pulse width of 7.2 ps and a pulse repetition frequency of 32.8 MHz has been realized with a semiconductor saturable absorber mirror (SESAM). The highest output power was 880 mW when the incident pump power was 7.1 W, corresponding to an optical conversion efficiency of 12.4%. The mode-locked pulse energy was about 26.83 nJ, while the peak power was 3.73 kW.
