Abstract

We report on high energy optical parametric oscillation of 118 mJ output with ~70% slope efficiency in 10 ns duration of 30 Hz operation by using Mg-doped congruent composition LiTaO(3) (MgLT). The periodically poled MgLT device with ~30 microm period for quasi-phase matching (QPM) in 5-mm-thick crystal are prepared. MgLT crystal could become a candidate for high-energy and higher durability material of QPM device, compared to conventional Mg-doped congruent composition LiNbO(3).

摘要

我们报道了使用掺镁同成分钽酸锂（MgLT），在30赫兹运行的10纳秒持续时间内实现了118毫焦输出、斜率效率约为70%的高能量光学参量振荡。制备了在5毫米厚晶体中用于准相位匹配（QPM）、周期约为30微米的周期性极化MgLT器件。与传统的掺镁同成分铌酸锂相比，MgLT晶体可能成为QPM器件高能量和更高耐久性材料的候选者。
