摘要

我们通过实验报道了氧化铝锌(AZO)作为一种新型的饱和吸收剂，可以产生在暗脉冲状态下工作的锁模激光。首先将单模光纤侧磨至1 dB插入损耗，制备出d型光纤。将偶氮氧化合物溶于异丙醇中，用滴铸法沉积在d型纤维上。在泵浦功率为65.7 ~ 101.35 mW的范围内，通过对腔的偏振进行优化，获得了稳定的暗脉冲。脉冲宽度为220 ns，脉冲重复频率为1.85 MHz。

Dark Pulse Mode-locked Laser based on Aluminum Zinc Oxide coated D-shape fiber as Saturable Absorber

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.

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
