Abstract

Eye-safe solid-state lasers that operate at 2 μm wavelength have many applications in medical, remote sensing and military technologies. With a 3-W CW laser-diode pumping, we obtained 760 mW 2.01 μm Tm:YAG laser under CW operation. The slope efficiency was 44% and the optical to optical efficiency reached 36%. In the acousto-optic Q-switched operation, laser pulses with the energy of 1.2mJ and 380 ns FWHM width have been achieved.

Energy-level diagram of Tm:YAG lasers. The 2 μm laser is generated from the transition of the lower Stark level of 3F4 to the higher Stark level of 3H6. The cross-relaxation between 3H4-3F4 and 3H6-3F4 can produce two laser photons with one pump photon.
