Abstract

The invention discloses a seed source spectrum broadening method, a seed source spectrum broadening device and a high-power continuous fiber laser system. The method comprises the following steps: outputting a polarization-maintaining narrow-linewidth continuous laser signal through a seed source; generating a pseudo-random bit sequence signal as a driving signal through the driving module, and outputting the driving signal to the power amplifier module, adopting the power amplification module for performing power amplification processing on the driving signal output by the driving module; adopting the phase modulator for receiving the polarization-maintaining narrow-linewidth continuous laser signal output by the seed source and the driving signal output by the power amplifier module, and broadening the polarization-maintaining narrow-linewidth continuous laser signal in a high-order phase modulation mode. According to the invention, the cost can be reduced while the structure is simplified, and the output power of the high-power continuous fiber laser system can be maximized.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a seed source spectrum broadening method, device and high-power continuous fiber laser system. Background technique [0002] Ultra-high power CW fiber laser has the advantages of high power, high reliability, high beam quality and convenient thermal management, etc., and has a wide range of applications in industrial processing, military attack and defense and other fields. In the military field, as the core part of laser weapons, high-power fiber lasers have the characteristics of smaller volume and lower energy consumption than solid-state lasers, which can solve the problem of fixed installation and expand their application to mobile carriers such as aircraft and ships. Therefore, many countries are advancing the development of laser weapons and increasing research efforts on high-power continuous fiber lasers, aiming to take the lead in this field.
