摘要： A passively mode-locked picosecond laser device comprising a pump source, a laser crystal, a laser cavity, a mode-locked output structure is provided. In the device, the pump source is placed at the side of the incident end surface of the laser crystal; the laser cavity includes a plane reflective mirror and a first plano-concave mirror, the reflective mirror is placed opposite to the concave surface of the plano-concave mirror and located on the position of the focal radius of the plano-concave mirror. The normal direction of the reflective mirror and the axis of the plano-concave mirror form a small angle therebetween; the laser generated from the laser crystal oscillates in the laser cavity, and output through the mode-locked output structure. The device uses a stable cavity design of the equivalent confocal cavity, which can increase the optical path, reduce the repetition frequency, and significantly reduce the cavity length and volume.
