Abstract: A pulsed second harmonic output is obtained from a continuously pumped laser at repetition rates in the 1-10 MHz range. This is accomplished by electrically pulsing an intracavity nonlinear element to establish momentarily the phase-matched condition required for second harmonic generation. The generated harmonic is a high-amplitude optical pulse which is coupled out of the cavity via a harmonic-transparent mirror.
