Power scaling of a picosecond vortex laser based on a stressed Yb-doped fiber amplifier is analyzed. An output power of 25 W was obtained for 53 W of pumping, with a peak power of 37 kW. Frequency doubling of the vortex output was demonstrated using a nonlinear PPSLT crystal. A second-harmonic output power of up to 1.5 W was measured at a fundamental power of 11.2 W.
分析了基于应力镱掺杂光纤放大器的皮秒涡旋激光器的功率缩放。在53W的泵浦功率下获得了25W的输出功率，峰值功率为37kW。使用非线性PPSLT晶体演示了涡旋输出的倍频。在11.2W的基频功率下测量到高达1.5W的二次谐波输出功率。
