Temperature influence on spectroscopic and lasing properties of blue laser diode pumped Alexandrite crystal
Original language description
We report on influence of temperature on spectroscopic and lasing properties of Alexandrite (Cr3+:BeAl2O4) crystal. Fluorescence lifetime, polarization-resolved absorption and emission spectra, and laser characteristics at similar to 750 nm are described in detail within the 78-400 K temperature range. As a pumping source, 3.5 W InGaN blue laser-diode operating at 444 nm wavelength was used. The best results achieved were at similar to 353 K crystal temperature - 326 mW of continuous output power at 750 nm wavelength with the slope efficiency near 20% (related to absorbed pump power). At cryogenic temperatures, the Alexandrite laser generation at the so-called R-line, i.e not in the vibronic mode, has been observed.
