Abstract

Q-switched output of 1.1 J pulse at a 2.053 μ m wavelength has been achieved in a diode-pumped Ho : Tm : LuLF laser with a side-pumped rod configuration in a master-oscillator-power-amplifier (MOPA) architecture. This is the first time to our knowledge that a 2 μ m laser has broken the joule per pulse barrier for Q-switched operation. The total system efficiency reaches 5% and 6.2% for single- and double-pulse operation, respectively. The system produces an excellent 1.4 times transform-limited beam quality.
