We describe a 2-/spl mu/m diode-pumped, room temperature Ho:Tm:YLF laser and end-pumped amplifier system. The Ho:Tm:YLF oscillator utilized a multiple folded resonator with eight mirrors. A Q-switched output energy of 109 mJ pulse was obtained at 6 Hz. This new design makes the laser a smaller size, which can be used in space application. The effects of the laser operating temperature, thermal focusing and resonator structure rigidity on the performance of the laser were also investigated. In order to increase the laser system energy and efficiency, an end-pumped Ho:Tm:YLF disk amplifier was designed. Preliminary results showed that the efficiency of this laser amplifier could be better than 3% during Q-switch operation, a factor of three increase over side-pumped amplifier configuration. The laser system performance and its potential use for remote sensing of wind are presented.
