An efficient high-power dual-wavelength lime-green Nd:YVO self-Raman laser is inventively developed by using two different lithium triborate (LBO) crystals. The first and second LBO crystals are employed to generate the 559 nm lime and 532 nm green lasers, respectively. The temperature of the first LBO crystal is fixed at the optimal phase matching, whereas the temperature of the second LBO crystal is tuned to flexibly control the relative strengths between the 532 and 559 nm waves. When the temperature of the second LBO crystal is set for the maximal total output power, the 532 and 559 nm output powers, respectively, are 7.1 and 2.9 W at a pump power of 31.6 W, corresponding to a conversion efficiency of 31.6%. When the temperature is controlled for the balanced output, the 532 and 559 nm powers, respectively, are 4.3 and 4.2 W at a pump power of 31.6 W, corresponding to a conversion efficiency of 26.9%.
一种高效的大功率双波长石灰绿 Nd:YVO 自拉曼激光器，通过使用两个不同的硼酸锂（LBO）晶体创新性地开发出来。第一和第二 LBO 晶体分别用于产生 559nm 的石灰绿和 532nm 的绿光激光。第一 LBO 晶体的温度固定在最佳相位匹配，而第二 LBO 晶体的温度可调，以灵活控制 532nm 和 559nm 波之间的相对强度。当第二 LBO 晶体的温度设置为最大功率时，在 31.6W 的泵浦功率下，532nm 和 559nm 的输出功率分别为 7.1W 和 2.9W，对应转换效率为 31.6%。当温度控制为平衡输出时，在 31.6W 的泵浦功率下，532nm 和 559nm 的输出功率分别为 4.3W 和 4.2W，对应转换效率为 26.9%。
