研制了一种高效率的腔抛式掺Yb：Y3+石榴石激光器。尽管掺Yb激光材料的高量子效率适合于高效率的激光振荡，但由于其准三/四激光的性质，其效率被降低。高强度泵浦的高增益运转适用于无极低温冷却的准三/四激光器的高效率振荡。在本课题组中，通过泵浦强度超过100kW/cm2的高增益运转，在室温下获得了连续波、纳秒到皮秒脉冲激光器的最高效率振荡。
High-efficiency cavity-dumped ytterbium-doped yttrium aluminum garnet (Yb:YAG) laser was developed. Although the high quantum efficiency of ytterbium-doped laser materials is appropriate for high-efficiency laser oscillation, the efficiency is decreased by their quasi-three/four laser natures. High gain operation by high intensity pumping is suitable for high efficiency oscillation on the quasi-three/four lasers without extremely low temperature cooling. In our group, highest efficiency oscillations for continuous wave, nanosecond to picosecond pulse lasers were achieved at room temperature by the high gain operation in which pump intensities were beyond 100 kW/cm2.
