Abstract

The importance of development of the visible lasers emitting in the green-blue spectral range under the laser-diode pumping enforces search for the new and optimization of the known active media for lasers pumped via up-conversion schemes. The YLF:Tm crystals are well-known active media for lasing on a number of lines over a wide spectral range from 0.450 to 2.35 μm upon selective laser, laser diode, and flash lamp pumpings, including up-conversion and ‘'avalanche” excitation mechanisms.
