Full characterization of a semiconductor laser beam by simultaneous capture of the near- and far-field
Conference poster, 2010
We present a new measurement technique for fully characterizing a semiconductor laser beam. The reflections from both surfaces of a planoconvex lens are used to simultaneously capture the near- and far-field. The optical phase is then retrieved using the Gerchberg-Saxton algorithm with improved numerical operations.
