摘要:Angular non-critical phase-matching (A-NCPM) second harmonic generation (SHG) for a Ti:sapphire laser was realized on LaCa4O(BO3)(3) (LaCOB) single crystals, grown by the Czochralski pulling method. Properties including the wavelength, bandwidth, effective nonlinear optical (NLO) coefficient (d(eff)), and acceptance angle were evaluated. At ambient temperature of 20 degrees C, the type-I NCPM (808 nm wavelength) was obtained along the y axis of LaCOB crystals, where the effective nonlinear optical coefficient (d(eff)), PM waveband, and angular acceptance were found to be of the order of 0.59 pm/V, 803 similar to 818 nm and 50.6 mrad cm(1/2) (Delta phi L), respectively. Moreover, high single-pass SHG conversion efficiency (44.6%) was achieved for 24.8 mm long Y-cut samples at 808 nm, using a mode-locked Ti: sapphire fundamental laser.
