8-HQCdCl2H2O as an organic Q-switcher in erbium laser cavity

摘要

This paper demonstrated a Q-switched erbium-doped fiber laser（EDFL） using an organic saturable absorber（SA） based on 8-HQCdCl2H2O material. The organic thin film was prepared using the casting process. The proposed Q-switched EDFL has a maximum repetition rate of 143 kHz, minimum pulse duration of 1.85 μs and the highest pulse energy of 167 nJ. The Q-switched peak laser was at a central wavelength of 1 531 nm with a 3 dB bandwidth of 3.52 nm and power intensity of 2.64 dBm.
