BRIEF COMMUNICATIONS: Generation of picosecond pulses by a gadolinium scandium gallium garnet laser
An investigation was made of a laser containing a gadolinium scandium gallium garnet crystal (GSGG:Cr3+:Nd3+) which was operated in the regime of passive mode locking. The duration of the output pulses was ~ 18 psec. The absolute efficiency was approximately 2.5 times higher than that of a YAG:Nd3+ crystal laser operated under similar conditions.
