Abstract
The experimental results of KTP optical parametric oscillator (OPO) pumped by Nd: YAG lasers were reported at wavelengths of 1064 nm and 532 nm with critically phase-matching and non-critically phase-matching. The eye-safe lasers have been demonstrated with tuning range of 1.53 to 1.84 μm, maximum energy of 130 mJ, and energy conversion efficiency as high as 64%. The tuning range, walk-off angle, acceptance angle, threshold and conversion efficiency were compared and analyzed, and the effects of walk-off on the beam quality and conversion efficiency of OPO were discussed.
