We demonstrated laser operation of a Er:YAG single crystal fiber at 1617 nm. Pumped on both sides by a laser diode at 1532 nm, a 600 μm diameter- 60 mm long- single crystal fiber produced an output power of 5.5 W once the wavelength 1617 nm was selected by an intracavity etalon. In Q-switched operation with an acousto-optic modulator, the laser produced an energy of 0.5 mJ at 100 Hz repetition rate with a pulse duration of 28 ns. The Watt level in average power was achieved for a repetition rate of 3 kHz with a pulse duration maintained around 30 ns
