abstract = "We demonstrate a wavelength tunable continuous wave single-frequency Cr:ZnSe laser based on a self-seeded ring cavity configuration in this paper. The laser system is based on anti-coated Cr:ZnSe crystal which has a length of 6 mm and a low signal transmission of 15\% (at 1908nm). Unidirectional operation of Cr:ZnSe laser is obtained by using a retro-reflecting device which can retro reflect a self-seed laser back into the ring cavity. The transmission of the output coupler is also optimized to get unidirectional operation. With three different birefringent filters inserting in the cavity, single-frequency operation with narrow linewidth is obtained. By rotating the angle of the birefringent filters, the laser's wavelength under single-frequency operation could be continuously tuned from 2338 nm to 2572 nm. The tuning range is over 200 nm. The maximum single-frequency output power is 0.92 W at wavelength of 2357 nm.",
