英文摘要	The diode laser having an elliptic beam and a Gaussian intensity distribution is transformed by graded index lenses and beam shaping prisms to a circular beam of small diameter and then focused to a point. The focused beam is then magnified by a compound meniscus lens and a collimating lens, producing a collimated flat beam of uniform intensity having negligible loss of the energy of the diode laser radiation. The design is easily implementable using all spherical surface lenses and industry standard glass types, producing a collimated, diffraction limited output beam.
