A. Robertson et Ai. Ferguson, SYNCHRONOUSLY PUMPED ALL-SOLID-STATE LITHIUM TRIBORATE OPTICAL PARAMETRIC OSCILLATOR IN A RING CONFIGURATION, Optics letters, 19(2), 1994, pp. 117-119
A broadly tunable picosecond singly resonant optical parametric oscill
ator based on a Brewster-angled crystal of lithium triborate in a ring
cavity is described. The optical parametric oscillator is synchronous
ly pumped by an all-solid-state frequency-doubled additive-pulse mode-
locked Nd:YLF laser pumped by laser diodes. Continuous noncritically p
hase-matched tuning is demonstrated from 839 to 1392 nm by use of one
set of optics. The oscillator has a threshold of 47 mW of average pump
power and, with a pump depletion of 70%, can deliver a tunable output
of as high as 88 mW.
