The tunability of Er:SrF2 laser was investigated at room temperature. Under pulsed laser diode pumping, the mid-infrared (2.75 μm) radiation was obtained with a maximal reached output power amplitude of 1.3 W and a slope efficiency up to 9.2 %. Laser tunability was reached using a MgF2 birefringent filter and the tuning range of 123 nm (2690 nm – 2813 nm) with Er:SrF2 was obtained.
