摘要：

The structural, optical, spectroscopic, and laser properties of purl and chromium-doped lithium-niobium germanate (LiNbGeO5) single crystals are discussed in this paper. Efficient stimulated Raman scattering (SRS), investigated with the one-micron fundamental and second harmonic wave of a picosecond Nd3+:Y3Al5O12 laser, reveals the potential of this new cubic non-linens susceptible (chi((3))) optical material for realizing effective solid state Raman shifters. The data are analyzed and compared with spectroscopic data from spontaneous Raman scattering. Pulsed tunable laser action of chromium-doped LiNbGeO5 crystals was demonstrated 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 excellent crystalline and optical properties, LiNbGeO5 is a promising material for tunable near-infrared lasers with integrated frequency converters. (C) 1998 Elsevier Science B.V.
