In our previous work we have observed instantaneous fluctuations (spiking) of Tm:YAP laser CW output, which can be explained by weak saturable assumption of water vapors inside the resonator and mechanical instability of laser. Such behavior of laser output can be inconvenient in applications like Cr:ZnSe laser pumping. The goal of our work was the comparison of diode pumped Tm:YAP laser with external...
Divalent chromium doped AIIBIV materials are attracting more and more attention during last years as perspective materials for development of efficient tunable mid IR solid-state lasers for different applications. Recent researches on development of continuous wave ZnSe:Cr2+ tunable lasers have demonstrated good results for laser diode pumped YAP:Tm3+ and YLF:Tm3+ optical pumping. The oscillation...
In our study we have investigated Cr:ZnSe bulk crystal samples grown by the special Bridgeman method. The Cr2+ ion concentration was 1x1019 cm-3. Cr:ZnSe crystal bulks with a diameter up to 50 mm and a length up to 100 mm were produced. From the bulk the Cr:ZnSe dispersive prism was polished. This Cr:ZnSe dispersive prism was utilized as a laser active material and simultaneously as a wavelength tuning...
