Influence of the spectral composition of the exciting radiation on the lasing and spectral luminescence properties of YSGG:Cr3+:Tm3+:Ho3+ and GSAG:Cr3+:Tm3+:Ho3+ crystals
Abstract:
The influence of the spectral composition of the pump radiation on the spectral luminescence and lasing characteristics of YSGG:Cr3+:Tm3+:Ho3+ (λlas = 2.088 μm) and GSAG:Cr3+:Tm3+:Ho3+ (λlas = 2.095 μm) crystals was studied. It was found that the GSAG:Cr3+:Tm3+:Ho3+ crystal exhibited good optical strength in the ultraviolet, so that a broad spectral range of the pump radiation could be utilized. This factor, combined with good thermophysical properties, should make this crystal a suitable active medium of efficient two-micron holmium lasers operated as a high pulse repetition frequency.
