We report the generation of the robust nanosecond Nd:YVO₄ solid-state laser and Er³⁺:ZBLAN fiber laser passively Q-switched by the tin selenide (SnSe) nanoflowers saturable absorbers. The SnSe nanoflowers prepared via chemical precipitation method exhibit broadband nonlinear optical absorption performance, and can modulate the separate lasers to deliver stable nanosecond pulse ∼1 µm and ∼2.8 µm successfully. The experimental results show that the low-dimensional transition-metal monochalcogenides hold great potential for the broadband robust saturable absorbers, and may pave an avenue toward developing high-performance broadband optoelectronic devices.

硒化锡纳米花被动调Q的鲁棒纳秒激光器

我们报告了强大的纳秒 Nd:YVO ₄固态激光器和 Er ³⁺ :ZBLAN 光纤激光器的产生，这些激光器由硒化锡 (SnSe) 纳米花可饱和吸收器被动调Q。通过化学沉淀法制备的 SnSe 纳米花表现出宽带非线性光吸收性能，并且可以调制单独的激光器以成功提供稳定的纳秒脉冲 ~1 µm 和 ~2.8 µm。实验结果表明，低维过渡金属单硫族化物在宽带鲁棒可饱和吸收体方面具有巨大的潜力，并可能为开发高性能宽带光电器件铺平道路。
