Abstract

The invention discloses a precise and adjustable multi-channel pulse synchronization triggering system, comprising: an input processing module, a precise delay module, a reset module, a coding and decoding module, and an output processing module; the input processing module performs preliminary processing on the input signal , send the preliminarily processed input signal to the precision delay module; input the delay value in the encoding and decoding module, and control the precision delay module according to the delay value, and control the precision delay module to The input signal is accurately delayed, and the precise delay signal is output; the output processing module enhances the precise delay signal; the reset module adjusts the reset time to adjust the signal width of the quasi-delay signal. The invention realizes that the synchronous trigger signal has the time interval jitter accuracy of the order of ns and ps, and simultaneously realizes the output of multi-channel synchronous trigger signals, and the output signal has steep front and rear edges of the trigger pulse, small jitter, and wide adjustable range of delay. feature.

Description

technical field [0001] The invention relates to the technical field of laser light sources, in particular to a precise and adjustable multi-channel pulse synchronization trigger system. Background technique [0002] For large-scale and high-power laser device light source systems, large-scale medical equipment, etc., the pulse delay trigger system is a very important and indispensable link. The time interval jitter accuracy of the synchronous trigger pulse will affect the operation efficiency and operation accuracy of these devices. . [0003] This type of laser device requires the trigger signal to be synchronized with the laser, so the us-level jitter accuracy is the basic requirement. Physically, the synchronization trigger signal is required to have a time interval jitter accuracy of the order of ns and ps. Since each trigger signal must have a relatively strict and precise time synchronization relationship, this requires the control system to have multiple synchronous ...

AI Technical Summary

Problems solved by technology

[0004] At present, the synchronous trigger delay device used in general laser systems not only has large jitter and poor delay adjustment accuracy; in addition, the delay time is adjusted by adjusting the length of the cable. Although the delay adjustment accuracy can be achieved, it cannot be continuously adjusted. And the volume is large, the adjustment range is small
