✦ Synopsis

Passive mode-locking of a pulsed Nd:YAG laser using a Cr 4+ :YAG saturable absorber was realized for the ®rst time in a nearly critical stable resonator containing an antiresonant ring structure. The output energy and pulse duration are 13.5 mJ and 180 ps, respectively. The recovery time and saturable intensity for excited-state absorption of Cr 4+ :YAG under the action of strong laser pulses were calculated from rate equations.
