Abstract: The principal spectroscopic and lasing characteristics of a Tm(15%):KY(WO₄)₂ crystal were investigated. The transition cross sections, the luminescence quantum yield, and the lifetime and the nonlinear depopulation coefficient of the upper active state were also determined. The slope efficiency of lasing at the 1950 nm wavelength was 45%. The feasibility of tuning in the spectral range 1850 — 1950 nm was demonstrated in principle.
