Abstract

An LD collimator was constructed, using an aspheric lens configuration for the transmitter of an optical intersatellite link. The design results show that the 5 mm diameter circular LD output beam whose rms wavefront aberration is better than (lambda) /100 is available in a two-or three-lens configuration. The first fabrication trial of the three-lens configuration achieved an rms wavefront aberration of better than (lambda) /16. This result proves that it is possible to obtain high wavefront performance, while reducing the required number of lenses when an aspheric lens configuration is adopted.
