基于Sb2O3可饱和吸收体的2.8μm被动调Q激光器
Passively Q-switched 2.8μm Laser Based on Sb2O3 Saturable Absorber
摘要
Abstract
In this paper,a passive Q-switched laser based on Sb2O3 saturable absorber Er3+-doped laser using a 978 nm pump was proposed.The Sb2O3 was successfully transferred onto an Al2O3 substrate by the chemical reaction assisted vertical micro sublimation method(CVMS),and its properties,such as morphology and structure were char-acterized.The Er3+-doped passive Q-switched laser based on Sb2O3-SA was achieved by using a 978 nm pump,with the maximum single-pulse energy and the maximum peak power of 6.84 μJ and 1.12 W,respectively.With the in-crease of the pump power,the pulse width decreased from 19.64 μs to 6.09 μs,and the repetition frequency in-creased from 19.10 kHz to 62.13 kHz.The center of the output laser wavelength is located at 2 793 nm and the FWHM corresponding to the wavelength at 2 793 nm is 9.10 nm.The experimental results showed that Er3+-doped passive Q-switched lasers based on Sb2O3 saturable absorber provide a new reference to realize lower-cost,more sta-ble~3 μm mid-infrared lasers with simpler resonant cavity using a novel saturable absorber.关键词
