Description

technical field [0001] The present application relates to the technical field of lasers and adaptive optics devices, in particular to a piezoelectrically driven deformable mirror for multi-beam incoherent spatial synthesis and an assembly method thereof. Background technique [0002] The output power of solid-state lasers is affected by various factors such as thermal effects, nonlinear effects, and surface quality of optical components. Combining the output beams of multiple lasers can obtain high-power laser output. The beam combining methods can be mainly divided into three categories: coherent combining, spectral combining and non-coherent combining. Incoherent spatial combination is one of the main methods of incoherent combination. Incoherent spatial combination is to combine the lasers emitted by multiple lasers for output through a series of beam shaping and transformation. This combination technology can increase the total laser output power, but it will affect th...
