Sum Frequency Generation of Dual-Wavelength Nd. YAP Laser in LiIO3 Crystal.

Abstract : Based on Sellmeier's equation for LiIO3 crystal, the phase-matched condition for sum-frequency generation of 1.0795 micrometers and 1.3414 micrometers dual wavelength Nd:YAP laser has been calculated. The calculated results agree well with the experimental ones. The CW and pulsed 0.5981 micrometers sum-frequency radiation have been achieved for the first time. jg p.4
