Abstract: CW lasing is obtained in Er³⁺(5%) : CaF₂ and Er³⁺(5%) : SrF₂ crystals near 2.75 μm with 0.4 and 2 W of output powers, respectively, upon transverse diode laser pumping into the upper ⁴I_11/2 laser level of erbium ions at 980 nm. Continuous tuning of the laser wavelength between 2720 and 2760 nm is realised in the Er³⁺ : SrF₂ crystal.
