Paper Abstract

TO utilize the mother lines to be perpendicular to each other in front and rear groups of cylindrical lenses, diffusing beam 44 degrees X 13 degrees from the window of semiconductor laser are compressed as 'parallel rays' to emerge into +/- 0.0025 rad. The sizes of the laser window are 0.1285 mm X 3.239 mm. The front focal points of cylindrical lenses in two groups are superimposed on the center of the window, and its types of second surfaces are hyperbolic and oval.
