Tm:YAG laser generating Q-switched pulses in the atmospheric window around the wavelength of 2036 nm
Original language description
We investigated the generation of radiation in the atmospheric window around the wavelength of 2036 nm using a Tm:YAG laser with a volume Bragg grating used for wavelength stabilization. The laser operated in both free-running and electro-optically Q-switched regimes. The Tm:YAG sample (4 at. % of Tm3+, 3 mm length, 3 mm diameter) was pumped by a laser diode emitting at 786 nm (pulse duration of 10 ms for free-running and 5 ms for Q-switching, repetition rate of 10 Hz). In the free-running regime, we achieved a maximum output power of 205 mW and a slope efficiency of 23.3 %, with a generated wavelength of 2036 nm. For Q-switched operation, we obtained pulses with a duration of 230 ns, a maximum pulse energy of 241 µJ, and a peak power of 817 W at 2036 nm.
