Abstract

A diode-pumped Q-switched Tm-doped double-clad fluoride fiber laser is reported providing up to 90 μ J pulse energy ( 160 ns , 100 kHz , i.e., 9 W of average power). The dependence of the fiber laser’s repetition rate on pump power and modulator repetition rate was investigated. By amplification even higher pulse energies of 410 μ J could be generated. In a second stage of the setup the Q-switched fiber laser serves as a pump for a gain-switched tunable Cr 2 + : ZnSe laser. The pulse energies reported are to the author’s knowledge the highest generated by Tm-doped fluoride fiber lasers or amplifiers today.
