本发明公开一种光谱合成的高亮度光纤激光放大器，光谱合成的高亮度光纤激光放大器包括多个激光放大器、整形装置及光谱合成装置。每个激光放大器用于将激光源进行多级放大以输出功率经过多级放大的第一光信号；整形装置用于对多个第一光信号进行准直及整形变换以输出多个第二光信号；光谱合成装置中入射端透射光栅结构及出射端透射光栅结构分别设置在波导片相背的两侧，入射端透射光栅结构用于将多个第二光信号耦合进波导片，波导片用于传输多个第二光信号至出射端透射光栅结构，出射端透射光栅结构用于使经过波导片的多个第二光信号合成为一个第三光信号并使第三光信号垂直于出射端透射光栅结构输出。

A fiber laser disclosed by the present invention comprises a plurality of laser amplifiers, a shaping device and a spectrum synthesis device. Each laser amplifier is used to carry out the multi-level amplification on a laser source to output a first optical signal of which the power is carried out the multi-level amplification, the shaping device is used to collimate, shape and transform the plurality of first optical signals to output a plurality of second optical signals, and an incident end transmission grating structure and an emergent end transmission grating structure in the spectrum synthesis device are arranged at the two opposite sides of a waveguide sheet respectively. The incident end transmission grating structure is used to couple the plurality of second optical signals in the waveguide sheet, the waveguide sheet is used to transmit the plurality of second optical signals to the emergent end transmission grating structure, and the emergent end transmission grating structure is used to synthesize the plurality of second optical signals passing the waveguide sheet into a third optical signal and output the third optical signal vertically with the emergent end transmission grating structure, so that the high-brightness and high-quality output of the fiber laser can be realized.
