Abstract

A self-starting all-solid-state picosecond (ps) laser was demonstrated. Different with a standard cavity design with semiconductor saturable-absorber mirror (SESAM), self-starting mode-locking was initiated by stretching the length of arm to reduce the beam spot, which shows the output beam possess higher beam quality than standard one. With a 10% output coupler, we achieved 1 W output power and 21 ps pulse duration at pump power of 4.5 W. High efficiency and high beam quality show the merit of the ps-laser.
