Mid-IR lasing of Fe2+ ions via Cr2+ -> Fe2+ energy transfer process with YLF:Er or laser diode pumping at 1.7 μm

Popis výsledku v původním jazyce

A nonradiative Cr2+ -> Fe2+ ions energy transfer process in Zn1-xMnxSe:Cr2+,Fe2+ (x = 0.05) single crystal with a Cr2+ to Fe2+ ions concentration ratio about 2.5:1 was investigated under short-pulse (200 ns) similar to 1.73 mu m excitation by YLF:Er laser. Fe2+ ions lasing in a temperature range from 78 K up to 200 K was achieved and the central oscillation wavelength was observed to increase from 4.1 mu m to 4.4 mu m, depending on the temperature of the active medium. Moreover, stable Fe2+ ions lasing under a "long" pulse excitation (1 ms, 10 Hz) by a similar to 1.71 mu m laser diode were demonstrated. The laser generated in a temperature range from 78 K up to 110 K at a central wavelength around similar to 4.17 mu m. The maximum mean laser output power of 4.1 mW with a slope efficiency of 2.3% with respect to the absorbed power was achieved. These results present a new possibility to develop a simple and compact diode-pumped coherent mid-infrared (4.1-4.3 mu m) laser sources.
