论文摘要
我们报告了单晶Zns中埋入的通道波导的第一个直接飞秒激光器编写。我们还报告了由飞秒激光写作制造的第一个单模CR：ZnS抑郁式覆层掩埋的波导激光。激光在2272 nm波长时产生150兆瓦的平均功率，坡度效率为11％。在1030 nm处的抑制覆层波导，在1030 nm的繁殖损失为0.62 db/cm，在1030 nm的飞秒泵中获得光谱拓宽。
We report the first direct femtosecond laser-writing of buried channel waveguides in monocrystalline ZnS. We also report the first single-mode Cr:ZnS depressed cladding buried waveguide laser manufactured by femtosecond laser writing. The laser yields 150 mW average power at 2272 nm wavelength with 11% slope efficiency. A depressed cladding waveguide with propagation loss of 0.62 dB/cm at 1030 nm allowed to obtain spectral broadening under femtosecond-pumping at 1030 nm.
