Lasing performance of the Tm:GAGG crystal in the 2 µm and 2.3 µm wavelength regions
This work presents the lasing performance of the Tm:GAGG crystal, which was successfully grown using the Czochralski method. The lasing performance of the Tm:GAGG crystal was demonstrated in both continuous-wave (CW) and Q-switching regimes. In the CW regime, the Tm:GAGG laser achieved a maximum average output power of 624 mW at 2000 nm and 220 mW at 2300 nm. Additionally, the Q-switching operation of the Tm:GAGG laser in the 2000 nm wavelength region was investigated, yielding stable pulses with a maximum output power of approximately 140 mW, a pulse duration of 190 ns, and a repetition rate of 31 kHz. To the best of our knowledge, this work represents the first detailed investigation of the lasing performance of the Tm:GAGG crystal, highlighting its potential applications in the mid-infrared wavelength region.
