In this paper, we report a diode side-pumped injection-seeded single-frequency Tm,Ho:YLF laser, which operated at lasing threshold and emitted 2051.2 nm. The assistance of Fabry–Pérot (FP) etalons to seed injection via mode selection was investigated. An acousto-optic Q-switched output 6.7 mJ achieved 5 Hz. A temporal pulse duration 310 ns with spectral linewidth 2.0 MHz frequency stability 0.8...
