Abstract
A LIDAR system may include a laser diode that emits a beam having a slow axis and a fast axis so that a cross-section of the beam has a width substantially greater than a height. A first three-element lens may be optically aligned with a photodetector of the LIDAR system. A second three-element lens may be optically aligned with the diode laser. The second three-element lens may include at least one lens having a predetermined astigmatism that reduces the width of the beam with respect to the height.
