ABSTRACT

We have experimentally reported aluminum zinc oxide (AZO) as a novel saturable absorber to generate a mode-locked laser operating in dark pulsed regime. The D-shaped fiber was first prepared by side polishing a single-mode fiber to the 1 dB insertion loss. The AZO was dissolved in isopropyl alcohol and then deposited onto the D-shaped fiber by drop casting method. By carefully optimizing the polarization of the cavity, a dark pulse was achieved, which remained stable within the pump power of 65.7–101.35 mW. Pulse width was 220 ns, and the pulse repetition rate was 1.85 MHz.

以铝锌涂层D型光纤为可饱和吸收体的暗脉冲锁模激光器

摘要

我们已经通过实验报道了铝锌氧化物 (AZO) 作为一种新型可饱和吸收剂，可产生在暗脉冲状态下运行的锁模激光器。D 形光纤首先是通过对单模光纤进行侧面抛光至 1 dB 插入损耗来制备的。AZO溶解在异丙醇中，然后通过滴铸法沉积在D形纤维上。通过仔细优化腔的极化，实现了暗脉冲，该暗脉冲在 65.7-101.35 mW 的泵浦功率内保持稳定。脉冲宽度为220 ns，脉冲重复率为1.85 MHz。
