我们报告的高功率中红外频率梳的发展与100 MHz的重复频率和100 fs的脉冲宽度。差频产生是在两个分支之间实现的，这两个分支来自Enfiber梳，分别在Yb：光纤和Er：光纤放大器中放大。在2.9 μ m闲频和1.6 μ m信号中分别产生6.7 W和14.9 W的平均功率。该光源具有高平均功率、优良的光束质量和无源载波包络相位稳定性，是产生远红外、可见光和深紫外宽带频率梳的一个很有前途的平台。(C)2020美国光学学会
We report on the development of a high-power mid-infrared frequency comb with 100 MHz repetition rate and 100 fs pulse duration. Difference frequency generation is realized between two branches derived from an Enfiber comb, amplified separately in Yb:fiber and Er:fiber amplifiers. Average powers of 6.7 W and 14.9 W are generated in the 2.9 mu m idler and 1.6 mu m signal, respectively. With high average power, excellent beam quality, and passive carrier-envelope phase stabilization, this light source is a promising platform for generating broadband frequency combs in the far infrared, visible, and deep ultraviolet.
