Abstract

We present an electro-optic (EO) Q-switched Er:ZBLAN fiber laser based on a customized La₃Ga₅SiO₁₄ (LGS) crystal. We investigate the effects of pump power and repetition rate on the laser output. At a repetition rate of 100 Hz, the laser generates stable pulses with a pulse width of 74 ns, pulse energy of 350 μJ, and peak power of 4.6 kW. At a repetition rate of 10 kHz, the laser achieves stable pulses with a pulse width of 159 ns, pulse energy of 15.7 μJ, and peak power of 99 W. Additionally, the laser exhibits a wavelength tuning range of approximately 90 nm at 2.7 μm under Q-switching modulation at 5 kHz. The results indicate that the laser provides stable pulse output in the 2.7 μm wavelength region.
