Abstract
The structural, optical, spectroscopic, and laser properties of purl a nd chromium-doped lithium-niobium germanate (LiNbGeO5) single crystals are discussed in this paper. Efficient stimulated Raman scattering (S RS), investigated with the one-micron fundamental and second harmonic wave of a picosecond Nd3+:Y3Al5O12 laser, reveals the potential of thi s new cubic non-linens susceptible (chi((3))) optical material for rea lizing effective solid state Raman shifters. The data are analyzed and compared with spectroscopic data from spontaneous Raman scattering. P ulsed tunable laser action of chromium-doped LiNbGeO5 crystals was dem onstrated in the spectral range between 1.3 and 1.52 mu m at cryogenic temperature and around 1.4 mu m at room temperature. Due to its excel lent crystalline and optical properties, LiNbGeO5 is a promising mater ial for tunable near-infrared lasers with integrated frequency convert ers. (C) 1998 Elsevier Science B.V.
