Abstract
Proposed here is a convenient optical system to collimate the crescent shape blue laser beam radiated from a Cerenkov SHG in channel waveguide configuration. This collimation system makes use of the reflection of a parabolic mirror and has a very large tolerance to the mirror displacement. The anisotropy of the nonlinear crystal on which the waveguide is fabricated has been taken into account. The optimum mirror location to obtain a collimated blue laser beam is given in accordance with Marechal's Criterion. By using an object lens, the collimated beam can be focused down with the spot size less than 1 micrometers .
