摘要: High-efficiency non-linear crystals suitable for the generation of coherent sources ranging from deep ultraviolet to mid-infrared (0.16 5 µm) are explored. The key parameters frequency conversion techniques (second-harmonic-generation, sumfrequency mixing, difference-frequency optical parametric oscillation (OPO) and stimulated Raman scattering) including tunability, beam quality, walk-off effective figure-of-merit analysed. Materials selection rules (for wide transparency, high damage threshold, stability, low absorption large figure-of-merit) presented. Techniques using non-critical phase-matching, quasi-phase-matching, waveguided doubling self-frequency Features applications new ofβ-barium borate, lithium triborate (LBO), potassium titanyl phosphate (KTP), KNbO3 MgO:LiNbO3 presented compared with other crystals. In addition a critical review, this paper also presents some results analysis frequency-conversion efficiency, experimental data OPO in KTP, LBO temperature-tuned phase-matching green lasers diode-pumped self-frequency-doubling crystal neodymium yttrium aluminium borate.
