Wavefront correction by a low-cost deformable mirror group in a small-aperture-beam fiber laser.


A low-cost deformable mirror (DM) group for wavefront correction in a small-aperture-beam fiber laser is reported in this paper. The DM group consists of nine single-actuator DMs and could act as a "virtual" 9-actuator DM arranged in a 3×3 array. The equivalent distance between two adjacent actuators could reach as small as 3 mm, which can lead to a… (More)
