Generation of second harmonic in a tunable/Q-switch Nd3+-doped fiber laser

摘要

Abstract: In this paper, we report second harmonic generation in a tunable/Q-switch Nd3$PLU@-doped fiber laser using a LiNbO$- 3$/-integrated optics device. The component is a low-voltage asymmetric Mach-Zehnder Interferometer. Laser emission occurs simultaneously at two wavelengths $lambda$-0$/ $EQ 1088 nm et $lambda$-2$/ $EQ 544 nm. As a driving voltage is applied to the LiNbO$-3$/ component, the lasing wavelengths are tuned by mode hopping. We demonstrate a Q-switch mode operating of that laser. !6
