Abstract

This application relates to a laser pulse shaping device and its method, pulse shaper, and optical system; the optical pulse shaping device includes: the pulse shaper is set on the optical path of the equipment connected to the laser light source, and the laser detection device is set on the actual object of the laser pulse position; the laser light source is used to generate laser pulses, which are transmitted through the optical path of the device and then emitted to the target; the laser detection device is used to measure the optical parameters of the laser pulses emitted to the target and send them to the control device The control device calculates the phase compensation parameter according to the optical parameter, and controls the pulse shaper to compensate the phase of the laser pulse passing through the optical path of the equipment according to the phase compensation parameter, so that the optical parameter of the laser pulse emitted to the object reaches the target value . This solution reduces the measurement complexity and can realize closed-loop testing. The pulse shaper can improve the accuracy of pulse compression compensation and enhance the effect of laser pulse use.

Description

technical field [0001] The present application relates to the field of laser technology, in particular to a laser pulse shaping device and method, a pulse shaper, and an optical system. Background technique [0002] In the laser pulse transmission process of the optical system, due to the dispersion in the optical path, especially the existence of second-order and higher-order dispersion, the laser pulse will produce a "time-domain broadening" effect when passing through the optical path, so that the laser pulse in the time axis The width on the time axis will increase with the propagation in the optical path, especially the femtosecond laser pulse. After the femtosecond laser pulse passes through the optical path, the width on the time axis even changes from femtosecond level to picosecond level. As a result, the peak power of the femtosecond laser pulse is greatly reduced, and the characteristics of the femtosecond laser pulse are lost. [0003] At present, optical system...
