Реферат:	eng: A 25 %Eu : KGd(WO4)2 crystal is grown by a modified Czochralski method and its spectral and lasing properties are studied. Generation of stimulated emission in this crystal on the 5D 0→7F4 transition of the Eu3+ ion is obtained, as far as we know, for the first time. The laser operates at room temperature at a wavelength of ∼703 nm under pumping into the 7F0→5D1 absorption band of the europium ion by the second harmonic of a Q-switched Nd :KGW laser (λpump = 533:6 nm). With a 9.4-mm-long active element, the output energy in the free-running regime reached 244 μJ, while the optical efficiency was 1.5 %. © 2011 Kvantovaya Elektronika and Turpion Ltd.
