Graded-reflectance mirrors for beam quality control in laser resonators.
Several types of small-dimension graded-reflectance mirrors deposited through rotating masks are compared. Multilayer mirrors provided with single-variable-thickness layers have limitations that are avoided when all the layers in the system are shaped. High-reflectance mirrors of the latter type are demonstrated. Numerical and experimental results are given.
