An injection-seeded, Q-switched Ho:YLF laser has been developed. For 13W pumping from a CW Tm:fiber laser, the energy and width of single longitudinal mode pulse are 5.5mJ and 50ns, respectively. The repetition rate is 1.25kHz.

The design and performance of a diode pumped Tm sensitized Ho LuLiF4 (LuLF) laser is described. The laser produced 135-mJ of Q-Switched output, which represents a slope efficiency of 0.09. To our knowledge this is the highest Q-Switched output for this material.

We report on remote sensing measurements of atmospheric carbon dioxide by a double pulsed 2-micron coherent differential absorption lidar technique.
Advanced Solid-State Photonics (2003), paper 309 | 2003
Songsheng Chen; Jirong Yu; Mulugeta Petros; Upendra N. Singhb; Yingxin Baia
Double-pass Tm:Ho:YLF laser amplifiers were developed and compared with single-pass amplifiers. The output energy was improved by 75% and the energy extraction efficiency was increased from 1.4% to 3.1% at 54-mJ input pulse energy.
