Single-passed passively mode-locked Nd:YVO4 picosecond laser with SESAM

摘要

We report on the LD-pumped passively mode-locked solid-state laser with SESAM (semiconductor saturable absorber mirror), in which the output beam is single passed through a flat mirror. The CW mode-locking pulse at 1064 nm, with an output power of 5 W, a pulse repetition rate of 98 MHz, and a pulse width of 25.3 ps. The beam quality is M-2 < 1.12 and the optical-optical efficiency is 35.7%.
