Abstract

A negative-feedback laser-power control technique has been applied, for the first time known to the authors, to mode locking in a cw Nd:YAG laser, leading to great long-term stability improvement in ultrashort-pulse generation. Output-power fluctuations during the active amplitude modulation have been markedly reduced by about 20 dB. The maximum tolerable detuning range for obtaining well-stabilized output power has been extended by nearly 1 order of magnitude.
