Double-front-end strong-field laser system with fast switching time sequence control device and method

The invention discloses a double-front-end strong field laser system with a fast switching time sequence control device and a method. The two front-end amplification systems are adopted, a front-end backup is provided for high-energy laser, when one front-end amplification system breaks down, the other front-end amplification system can be utilized, and therefore it is guaranteed that the whole laser system can still be used continuously; under the condition that the laser pulse and the pump are pulse, a certain time sequence requirement exists between the amplified laser pulse and the pump pulse, so that the pump pulse, the amplified laser pulse and other electronic devices needing to be synchronized with the pulse on a laser light path are required to be synchronized in time; a timing sequence needs to be provided to the devices through an external clock, so that the laser can be amplified, and a timing system is a very important system of the laser. According to the invention, time sequence control laser i
