分析了基于应力掺镱光纤放大器的皮秒涡旋激光器的功率定标。在抽运功率为53 W时，获得了25 W的激光输出，峰值功率为37 kW。使用非线性PPTORE晶体证明了涡旋输出的倍频。在基波功率为11.2W时，获得了高达1.5W的二次谐波输出功率。
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.
