基于SESAM的被动调Q光纤光栅掺铒光纤激光器
SESAM-based passively Q-switched Bragg fiber grating Er-doped fiber lasers
摘要
Abstract
This paper proposes and studies a linear-cavity-structured passively Q-switched Bragg fiber grating Er-doped fiber la-ser 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 power 143 mW and slope efficiency 1.2%.When the pump power is increased from 149 mW to 180 mW,the pulse repetition frequen-cy obtained can be increased from 5.431 kHz to 9.778 kHz.When the pump power is 155 mW,the fiber pulse energy is 5.6 nJ and the pulse width is 40μs with a repetition frequency of 6.538 kHz.关键词
