LITTLE KNOWN FACTS ABOUT DIFFUSION BONDED CRYSTAL.

Passively Q-switched operation yields twin-frequency emission of two unsynchronized laser pulses carried by unique transverse modes whereas active Q-switched configuration offers the possibility of synchronizing emission at The 2 wavelengths.Multi-wavelength Procedure of Q-switched Nd-doped YGd2Sc2Al2GaO12 garnet ceramic lasers is investigated.
