This laser has a very fast axis and slow axis. It will always emit a "stripe" rather than a DOT or Gaussian type beam. 2 ways to correct this, anamorphic prism pair, or perfect cylinder lens mounted below focusing lens to slow down fast axis (LONG PART OF BEAM)
This is a problem for bar lasers too which emit the laser from a very, very fast axis or multiple facets. They usually couple with cylinder or glass ball lens.. So, yes, there are ways, but most people are just happy to get the beam out of it. The slow and fast axis are actually called parallel and perpendicular axis, it would show on a datasheet if we could ever find for sure who makes the diode for Casio.
