Abstract

This paper proposes and studies a linear-cavity-structured passively Q-switched Bragg fiber grating Er-doped fiber laser using a Semiconductor Saturable Absorber Mirror（SESAM）.This laser controls the polarization state of laser without the need to use a polarization controller

thus simplifying its structure.Its central wavelength is 1 549.975 nm

threshold power143 mW and slope efficiency 1.2%.When the pump power is increased from 149 mW to 180 mW

the pulse repetition frequency obtained can be increased from 5.431 kHz to 9.778 kHz.When the pump power is 155 mW

the fiber pulse energy is 5.6nJ and the pulse width is 40μs with a repetition frequency of 6.538 kHz.
