Thermally driven dual-frequency Q-switching of Nd:YGd2Sc2Al2GaO12 ceramic laser

Résumé

Multi-wavelength operation of Q-switched Nd-doped YGd2Sc2Al2GaO12 garnet ceramic lasers has been investigated. Dual-wavelength emission around ~1.06 µm has been demonstrated both in the actively and passively Q-switched configurations. The ratio of output energy between the two laser wavelengths was driven by the temperature elevation caused by pumping. Passively Q-switched operation yields dual-frequency emission of two unsynchronized laser pulses carried by distinct transverse modes whereas active Q-switched configuration offers the possibility of synchronizing emission at the two wavelengths
