Abstract

In this paper, a high-power UV-pumped BBO optical parametric oscillator (OPO) is presented by increasing the working temperature of the nonlinear crystal to fasten the color center recovery speed and further decrease the color center density. When the working temperature of the BBO crystal was experimentally increased from 135 °C to 185 °C, the output power was scaled up from 1.20 W to 2.17 W. The repetition rate and pulse width of the signal light were 10 kHz and 5.23 ns, respectively. By rotating the BBO crystal, the wavelength of the signal light was tuned from 409.81 nm to 581.87 nm. To the best of our knowledge, it was the highest output power for the 355 nm UV-pumped II-type critical phase-matched BBO OPO. The results are beneficial for the development of OPOs as well as in industrial and scientific research fields.

基于色心密度降低的大功率紫外泵浦光参量振荡器的实现。
本文提出了一种大功率紫外泵浦BBO光参量振荡器(OPO),通过提高非线性晶体的工作温度来加快色心恢复速度,进一步降低色心密度。当实验将BBO晶体的工作温度从135℃提高到185℃时,输出功率从1.20 W增加到2.17 W。信号光的重复频率和脉冲宽度分别为10 kHz和5.23 ns。通过旋转BBO晶体,信号光的波长从409.81 nm调谐到581.87 nm。据我们所知,这是355nm紫外泵浦ii型临界相位匹配BBO OPO的最高输出功率。研究结果对OPOs的发展以及工业和科研领域都有一定的指导意义。
