SOLID-STATE AND LIQUID LASERS: Compact GSGG:Cr3+:Nd3+ laser with passive Q switching
An experimental investigation was made of a compact gadolinium scandium gallium garnet (GSGG) laser activated with Cr3+ and Nd3+, and containing phototropic centers. The active element of this laser performed the function of a passive Q switch. Lasers of this kind were demonstrated to be capable of generating nanosecond pulses with an energy of up to 5 mJ per pulse.
