Description
Technical field [0001] The invention relates to the field of engineering and civil initiation system design, in particular to a multi-channel pulse ignition laser initiation system. Background technique [0002] At present, engineering and civil initiating equipment and systems basically use electric explosive tubes as ignition devices. However, the wires used in the electric detonation tube and the electric detonation system may be coupled with high-frequency electromagnetic pulses to trigger the initiating device by mistake, and the electronic devices used in the electric detonation system have complex manufacturing processes, high costs, and reliability. In view of the above-mentioned safety problems of electric initiation systems, laser initiation systems, as a new type of initiation mode, have received increasing attention for their research and engineering. [0003] It can be seen from the current use situation that the multi-channel pulse ignition laser initiation system is...
