The beam of the laser diode was collimated by a spherical and cylindrical lens and focussed by a 45 mm achromatic lens into Cr2+:ZnSe crystal. Output power of 105 mW and slope efficiency of 35% were obtained with respect to the absorbed pump power. The laser threshold pump power varied between 45 mW and 77 mW and the variation depended on mirror transmission.enoptical pumpingoptisches Pumpendiode laserDiodenlaserinfrared laserInfrarot-Laserhigh powerLeistungslaserGaSb621667Efficient 100 mW Cr(2+): ZnSe laser pumped by a 1.9 µm laser diode100 mW Cr(2+): ZnSe Laser hoher Effizient durch 1.9 µm Diodenlaser gepumptconference paper
