Abstract

We describe a pulsed doubly resonant LiB₃O₅ (LBO) optical parametric oscillator (OPO) pumped with a frequency doubled Q- switched Nd:YAG laser amplifier. The threshold power density near degeneracy was found to be 29 MW/cm². The OPO was continuously tuned from 970 nm to 1175 nm by rotation of the LBO crystal. The linewidth of the signal radiation at 998 nm, and idler radiation at 1136 nm wavelength, were found to be 10 nm, and 13 nm respectively. The OPO output pulse energy of signal and idler near degeneracy was 1.51 mJ for 18 mJ pump energy.
