Abstract

We report on developing two flashlamp-pumped electro-optically Q-switched Cr:Er:YSGG lasers with the Q-switch based on La3Ga5SiO14 crystal. The “short” laser cavity was optimized for applications requiring high peak power. In this cavity, the 300 mJ output energy in 15 ns pulses at 3Hz repetition rate was demonstrated under pump energy below 52 J. However, several applications, such as Fe:ZnSe pumping in a gain-switched regime, requiring longer (~ 100 ns ) pump pulse duration. We developed a 2.9 m long laser cavity capable of delivering 190 mJ of output energy in 85 ns pulses for these applications.
