Abstract

The invention discloses a device capable of adjusting the diameter of a focusing light spot on a saturable absorption mirror. The device includes a base plate, and a motor A, a guide rail A, a guide rail B, a motor B, a focusing mirror B and a light source are sequentially arranged on the base plate from left to right. The guide rail A is mounted on a middle shaft above the base plate through a screw, a sliding seat A is arranged on the guide rail A, and the saturable absorption mirror is fixedly arranged on the sliding seat A. The guide rail B is fixedly mounted on the central axis of the base plate through screws, a sliding seat B is arranged on the guide rail B, and a focusing mirror A is fixedly arranged on the sliding seat B. The motor A is fixed on the base plate through screws, themotor A controls the sliding seat A to move on the guide rail A, and the motor B is fixed to the base plate through screws and controls the sliding base B to move on the guide rail B. By adjusting thedevice, the stable and adjustable output power of an ultrafast laser can be realized, and the problem of losing lock or multiple pulses cannot be caused while the output power is adjusted by changinga pumping current.

Description

technical field [0001] The invention relates to the technical field of laser light adjustment, in particular to a device capable of realizing the adjustable focus spot diameter on a saturable absorption mirror. Background technique [0002] There are usually two types of optical collimation and focusing methods widely used for saturable absorbing mirrors. One is to use the combination of focusing lenses to focus the light in free space onto the saturable absorbing mirror. The diameter of the focused spot can be focused by designing It is relatively controllable to control the parameters of the lens; the other type generally appears in fiber ultrafast lasers, which is realized by directly bonding the saturable absorbing mirror to the end face of the fiber with optical glue. The diameter of the spot on the laser is basically the same as the core diameter of the fiber used, which is almost uncontrollable, but the advantage is that the laser is more stable as a whole because no ...
