beta-barium borate optical parametric oscillator pumped at third harmonic of Q-switched multiaxial Nd:YAG laser

摘要

The singly resonant operation of a BBO OPO pumped by the third harmonic of the Q-switched Nd:YAG laser was demonstrated. Output energies of the visible pulses higher than 100 mJ, and total conversion efficiencies higher than 50 percent at multiaxial pumping with average power of few watts were achieved. The OPO was tunable over the range 405- 2900 nm.
