A diode-side-pumped Tm,Ho:LuLiF laser at 2-pm wavelength obtained in a ring resonator and its amplification experiment are reported.At the maximum pump energy of 4.7 J available for the oscillator,the output energy per pulse for the oscillator decreases from 904 to 483 mJ in free running mode,and decreases from 106 to 68 mJ in Q-switched mode,with an increase of pump pulse repetition rate from 1 to 5 Hz.When considering the amplifier,99-mJ Q-switched output energy is achieved at 5-Hz repetition rate.
