Generation of subpicosecond pulses from a continuous-wave mode-locked Nd:YAG laser using a two-stage optical compression technique

Abstract
By using a two-stage optical-fiber grating pair pulse-compression technique, 1.06-μm pulses as short as 0.7 psec have been obtained from an actively mode-locked cw Nd:YAG laser. This represents an overall pulse-compression ratio of 113.
