Multi-wavelength intermediate infrared sequence pulse laser

The invention provides a multi-wavelength mid-infrared sequence pulse laser. The multi-wavelength mid-infrared sequence pulse laser comprises a pump laser module, a laser Q-switching module, a light beam control module and a mid-infrared laser module which are arranged along a light path, wherein the pump laser module is used for generating continuous pump light; the laser Q-switching module is used for adjusting the intra-cavity loss of the pump laser module so as to enable the continuous pump light to form a sequence pulse laser, and the sequence pulse laser is also used as the pump light of the intermediate infrared laser module; the light beam control module is used for carrying out light beam shaping on the formed sequence pulse laser; the mid-infrared laser module is used for absorbing the sequence pulse laser and forming multi-wavelength mid-infrared laser output periodically. As a novel solid laser, compared with an existing mid-infrared laser, the laser has the advantages that multi-wavelength high-frequency time sequence output is achieved, each output wavelength has the advantages of being high in repetition frequency and high in peak power, and the laser has extremely important significance in expanding the practicability and application range of the mid-infrared laser.
