Diode pumped continuous and quasi continuous laser operation of TGT-grown Nd,Y-codoped:SrF2 crystal
Original language description
In this paper we present laser properties of newly prepared TGT grown Nd,Y:SrF2 crystals with neodymium concentration of 0.4, 0.65 and 0.8 at.%. The noncoated crystal samples 3.1 or 5 mm long were pumped by a 796 nm laser diode matching the Nd:SrF2 absorption peak. In the pulsed pumping regime (pulse-duration 2 ms, frequency 10 Hz), the maximum average output power of 75 mW was obtained with the slope efficiency as high as 51% and the optical-to-optical efficiency of 44% with respect to the absorbed pump power. The oscillations started at the wavelength of 1057 nm. At higher pumping levels, the second emission line at 1050 nm appears. Wavelength tuning using birefringent filter from 1048 to 1070 nm is probably given by crystal-field splitting of the 4F3/2 manifold in Nd3+. True-CW laser operation was also successfully obtained at lower pumping level with the maximum output power of 380 mW and the optical-to-optical efficiency of 16% at the wavelength of 1057 nm.
