β-BaB_2O_4 optical parametric oscillator

This paper reports firstly the single- and doubleresonant β-BaB2O4 optical parametric oscillators (OPO) pumped by second harmonics of a 1.064μm Nd:YAG laser. The tuning range of OPO covers 0.83-0.89,μ\m, 0.97-1.18μm and 1.63-1.73μm. The maximum energy output of SRO (Single-Resonant Oscillator) and DRO (Double-Resonant Oscillator) s ImJ/pulse and 200μJ/pulee respectively.
