“…Previously, lasing under in-band pumping was obtained in various erbium-containing materials, such as garnet [3,5], vanadate [6 - 9], sesquioxide [10] and tungstate [11,12] crystals. The maximum slope efficiency with respect to the absorbed pump power for the Er : LuVO 4 crystal pumped by a fibre laser was 64 % in the cw regime [8].…”

Abstract. Spectroscopic properties of Er : LiLuF 4 and Er : LiYF 4 crystals in the spectral region near 1.5 mm and the lasing characteristics of these crystals under in-band pumping at a wavelength of 1522 nm are studied. With the Er : LiLuF 4 crystal, the maximum slope efficiency with respect to the absorbed pump power was 44 % at a wavelength of 1609 nm. Continuous-wave operation of an inband pumped Er : LiYF 4 laser is obtained for the first time. The output power at a wavelength of 1606 nm was 58 mW with a slope efficiency of 21%.
