摘要

A high-power 880-nm diode-directly-pumped passively mode-locked 1342 nm Nd:YVO_(4) laser was demonstrated with a semiconductor saturable absorber mirror (SESAM). The laser mode radii in the laser crystal and on the SE-SAM were optimized carefully using the ABCD matrix formalism. An average output power of 2.3 W was obtained with a repetition rate of 76 MHz and a pulse width of 29.2 ps under an absorbed pump power of 12.1 W, corresponding to an optical-optical efficiency of 19.0percent and a slope efficiency of 23.9percent, respectively.
