为了获得一维温度梯度并降低晶体的温升，基于高纵横比的微厚度平板结构研制了一种高效大功率Yb：Y3 Al 5 O 12振荡器。在泵浦功率为608 W时，获得了257 W的连续激光输出，光转换效率为42%。
A high-efficiency and high-power Yb:Y3Al5O12 oscillator was developed based on the microthickness slab structure with high aspect ratio to obtain one-dimensional temperature gradient and to reduce the temperature increase in the crystal. Laser output power of 257W was obtained in cw oscillation with 42% optical conversion efficiency at a pump power of 608W.
