We report a CW, watt-level, red, green, and blue (RGB) laser pumped by an economical multimode (1-nm linewidth) Yb-fiber laser at 1.064 mum. A singly resonant optical parametric oscillator at 1.56 mum has two intracavity sum-frequency generators for red and blue laser generation. An extracavity second harmonic generator converts the residual pump power into green laser radiation. At 25-W pump power, the laser generated 3.9, 0.456, and 0.49 W at 633, 532, and 450 nm, respectively. The multimode pump laser offers a large temperature bandwidth for operating the RGB OPO without the need of a precision crystal temperature stabilizer.
我们报道了一种由经济实惠的多模(线宽1纳米)1.064微米掺镱光纤激光器泵浦的连续波、瓦级红、绿、蓝(RGB)激光器。一个1.56微米的单谐振光参量振荡器有两个腔内和频发生器用于产生红色和蓝色激光。一个腔外二次谐波发生器将剩余的泵浦功率转换为绿色激光辐射。在25瓦泵浦功率下,该激光器在633、532和450纳米处分别产生了3.9瓦、0.456瓦和0.49瓦的激光。这种多模泵浦激光器为运行RGB光参量振荡器提供了较大的温度带宽,无需精密的晶体温度稳定器。
