Abstract

The invention discloses a high peak power mid-infrared tunable laser emission device and method, the device includes: a pump source for generating a laser beam, and adopts nonlinear phase conjugate wavefront distortion compensation for the laser beam technology to compensate laser wavefront distortion, use Fabry-Perot etalon to narrow line width technology to squeeze laser line width, and use binary optical technology to improve laser spot distribution; optical shaping module is used to process the pump source The final laser is optically shaped to obtain a laser beam with a flat top distribution, and the shaped laser beam is expanded; the frequency conversion control module is used to adjust the placement angle of the OPO crystal in the OPO module; the OPO module is used to use the OPO The crystal performs wavelength conversion on the laser beam processed by the optical shaping module, and outputs a mid-infrared tunable laser. The invention can take into account both high peak power and tunability, and can achieve wider application in mid-infrared laser interference.

Description

A high peak power mid-infrared tunable laser emitting device and method technical field The invention relates to the technical field of photoelectric countermeasures, in particular to a high peak power mid-infrared tunable laser emitting device and method. Background technique There are two main types of existing low repetition frequency mid-infrared laser emission technology: one is non-tunable 10MW mid-infrared laser emission technology; the other is tunable 1MW mid-infrared laser emission technology. Among them, the peak power of the tunable 1MW mid-infrared laser emission technology is low. In the application of mid-infrared laser interference, the interference efficiency cannot reach the level of laser blinding, and there is a problem of short interference distance and poor effect; it is not tunable The mid-infrared laser emission technology of the 10MW level can reach the level of laser blindness in terms of interference efficiency, but because its wavelength is not...
