Time division multiplexing-based multiplexed output high-power laser device front-end system with high signal-to-noise ratio

The invention relates to a time division multiplexing-based multi-output high-power laser device front-end system with a high signal-to-noise ratio. The system comprises a laser seed source, a multi-path beam splitting unit, an optical fiber amplifier, an electro-optical modulator, an arbitrary signal generator, a 1 * N radio frequency switch, a radio frequency amplifier and a digital delay generator, the digital delay generator sequentially triggers the laser seed source, the electro-optical modulator, the arbitrary signal generator and the 1 * N radio frequency switch. The 1 * N radio frequency switch distributes and outputs a plurality of electric signals output by a single channel of any signal generator to multiple paths under the control of the logic circuit, and the electric signals are loaded to a plurality of electro-optical modulators, so that any shaping output of multiple beams of light pulses is realized. According to the invention, the requirement that a high-power laser device generates multipl
