Abstract

The divergence angles of the single-mode Gauss beam generated by GaAlAs SDL-5400 LD laser in the perpendicular directions are not equal,and there is astigmatism in the beam.In order to obtain the circular light spot with common beam waist,a collimating and shaping module with two semi-cylinder perpendicular lenses and a pair of prisms was designed according to the complex parameterand ABCD-law.The far-field divergence angle of the collimated and shaped LD laser beam,which was calibrated with CCD,was 0.53 mrad in the sagittal direction and 0.64 mrad in the meridional direction.
