Abstract

Power fluctuations in a diode-pumped intracavity-doubled Nd:YVO4 microchip laser have been analysed. Their relationship with the coupling of several longitudinal modes has been experimentally demonstrated. Although second-harmonic power is generated by the nonlinear crystal, the effect of sum-frequency generation is also involved. This effect produced 9 spectral peaks at 532 nm when 5 longitudinal modes at 1064 nm were oscillating simultaneously.
