Mode self-locking in a laser with combined Q switching

An experimental investigation was made of the feasibility of achieving mode self-locking in a neodymiumglass laser with combined. Q switching by optomechanical and phototropic modulators. A study was made of the characteristics of the output radiation and it was found that mode self-locking was achieved on introduction of an additional semitransparent mirror into the resonator. The attainment of self-locking under combined Q-switching conditions reduced the number of ultrashort pulses in the output and stabilized the beginning of stimulated emission.
