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

Abstract:

This letter demonstrated a Q-switched Erbium-doped fiber laser using an organic saturable absorber 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, a minimum pulse duration of 1.85 ?s and highest pulse energy of 167 nJ. The Q-switched peak laser was at central wavelength of 1531 nm with a 3-dB bandwidth of 3.52 nm and power intensity of 2.64 dBm
