In　order　to　meet　the　requirements　of　the　new　laser　radar　and　laser　active　lighting　for　the　miniaturized　line　light　source,　a　linear　laser　light　source　that　can　be　transmitted　over　long　distances　has　been　successfully　designed　and　prepared.　This　linear　laser　light　source　is　based　on　808nm　semiconductor　laser.　Firstly,　a　set　of　orthogonal　placement　plano-convex　aspherical　lens　is　used　for　collimating　the　laser　beam　of　gauss　distribution,　thus　the　parallel　beams　that　can　be　transmitted　over　long　distances　is　obtained,　and　then　through　the　Powell　prism.　Finally,　the　semiconductor　laser　is　shaped　into　a　laser　light　source　with　the　slender　and　uniform　intensity　distribution.　And　we　also　have　carried　out　an　example　design　simulation　with　the　Zemax　optical　design　software　and　built　an　experimental　system,　and　a　laser　light　source　has　been　successfully　prepared　with　the　divergence　angles　54　degrees　of　the　fast　directions　and　the　uniformity　23.5%　of　the　linear　spot.　The　experimental　results　can　match　the　Zemax　simulation　results　well,　which　proves　that　the　design　method　in　this　article　is　correct,　simple　and　useful.
