Temperature dependence of spectroscopic properties of cryogenically cooled Tm3+:LuF3-CaF2 diode pumped laser

with maximum output energy up to 20 mJ and slope efficiency 64 %. From the results it follows that the temperature has a strong influence on laser slope efficiency and laser threshold. With decreased of temperatur...

Ho:GGAG disordered garnet crystal for tunable 2.1 µm laser

Room-temperature 2.1 µm laser based on a novel Ho3+-doped disordered garnet Gd3(Ga,Al)5O12, resonantly pumped by a Tm:fiber laser, was investigated. Slope efficiency of 45 % and a wavelength tunability in the range 2055-2116 nm was ...
