Abstract

The invention discloses a passive mode-locking plate strip laser. The passive mode-locking plate strip laser comprises a semiconductor pumping source (1) used for outputting pumping light, a coupled system (2), a dichroic mirror (3), a plate strip crystal (4), a plane total reflective mirror (5), a first plane-convex mirror (6), a first plane-concave mirror (7), a second plane-concave mirror (8), a second plane-concave mirror (9), a semiconductor saturable absorption mirror (SESAM) (10), a second plane-convex mirror (11) and an output mirror (12). A mode locking laser technique is combined with an end face pumping plate strip laser technique, and the heat dissipation problem of a gain medium in a high power mode locking laser technique is solved; passive mode locking is conducted by using the semiconductor saturable absorption mirror (SESAM), the output power is high, the single pulse energy is large, and the wide application prospect is obtained.

Description
