Abstract

A high-power 532 nm-pumped multikilohertz nanosecond optical parametric oscillator using a periodically poled $1.0\mathrm{mol}.\%$ $\mathrm{MgO}$-doped stoichiometric lithium tantalate crystal that could be operated from room temperature to 200°C without damage is reported. A broad continuous tuning range from 855 to $1410\mathrm{nm}$ was achieved within a single domain period. Efficient operation of high peak power and watt level average power with a power conversion of 62.5% was measured. These results show that a high-resolution high average power visible tunable source can be realized.
