Abstract: Methods of wavelength tuning of a polycrystalline Cr²⁺ : ZnSe laser pumped by a repetitively pulsed Tm : YLF laser (pulse duration ~100 ns, pulse repetition rate 3 KHz) are studied. With the use of a prism selector, the laser wavelength was tuned within the range of 2070 – 2400 nm at a linewidth of 11 nm for a SiO₂ prism and 30 nm for a CaF₂ prism. The use of a Lyot filter made it possible to tune the Cr²⁺ : ZnSe laser wavelength (with replacement of the cavity mirrors) within the spectral ranges of 2130 – 2400 and 2530 – 2750 nm at a linewidth of 4 nm.

Keywords: mid-IR region, Tm : YLF laser, polycrystalline Cr²⁺ : ZnSe laser, prism selector, Lyot filter.
