High-average-power intracavity second-harmonic generation using potassium titanate phosphate (KTiOPO4) in an acoustooptically Q-switched neodymium:YAG laser oscillator at 5 kHz

High-average-power intracavity second-harmonic generation using potassium titanate phosphate (KTiOPO4) in an acoustooptically Q-switched neodymium:YAG laser oscillator at 5 kHz. Liu, Yung S.; Dentz, D.; Belt, R. (Gen. Electr. Res. Dev. Cent., Schenectady, NY 12301, USA).There are some reagents with their cas registry numbers 12690-20-9 and 12005-21-9 are used in this study. Opt. Lett., 9(3), 76-8 (English) 1984. CODEN: OPLEDP. ISSN: 0146-9592. DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) High-av.-power 2nd-harmonic generation was demonstrated with an output power of 5.6 W at 532 nm by intracavity frequency doubling using Type II KTiOPO4 in a Nd:YAG laser oscillator acoustooptically Q switched at 5 kHz. The av. power achieved, limited only by the power-supply current available in these expts., was ~3 times higher than what has been obtained in a state-of-the-art device using LiIO3 as the doubler. More significantly, since no intrinsic limitations, such as satn. and material damage, have yet been obsd., further improvement in the power output should be achievable. Previous studies on intracavity 2nd-harmonic generation were limited to the small-signal case; the present result shows the feasibility of operating an internally doubled oscillator for efficiently converting the fundamental to its harmonic in a high-power device. .

Calculations of optimum phase-match parameters for the biaxial crystal potassium titanate phosphate (KTiOPO4). Yao, J. Q.; Fahlen, Theodore S. (XMR, Inc., Santa Clara, CA 95051, USA). J. Appl. Phys., 55(1), 65-8 (English) 1984. 12690-20-9 which is the cas registry number is also used here. CODEN: JAPIAU. ISSN: 0021-8979. DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) The expression for the optimum phase-matching angle for the biaxial crystal KTiOPO4 (KTP) is presented and numerically calcd. The theor. effective nonlinear coeff., walk-off angle, and conversion efficiency were detd. The results provide some theor. and practical guidance for optimum operation of biaxial crystals, with specific numerical calcns. for KTP. .
