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.


Se han analizado las fluctuaciones periódicas de potencia que aparecen en un láser microchip de Nd:YVO4 doblado en frecuencia, demostrando que se deben a la oscilación simultánea de varios modos longitudinales. Se ha mostrado que, además del doblado de frecuencia, también se produce el efecto de suma de frecuencias, observando hasta 9 máximos espectrales en 532 nm cuando oscilan simultáneamente 5 modos longitudinales en 1064 nm.
