The lasing characteristics of a Cr{sup 2+} : ZnSe crystal grown by the method of free growth on a single-crystal seed using physical transport in helium are studied. The crystal was doped from a vapour phase during its growth. The achieved concentration of dopant Cr{sup 2+} ions (5x10{sup 18} cm{sup -3}) provides the absorption coefficient of 4.5 cm{sup -1} at the maximum of the pump band (1.78 {mu}m). Upon pumping by a pulsed Co : MgF{sub 2} laser at 1.67 {mu}m, the slope efficiency equal to 59 % with respect to the absorbed energy was achieved, which corresponds to the quantum efficiency 87 %.
