So you can test out this one , no gamedata.txt needed , if you want to adjust the BeamPosition search for this and after changing compile it yourself:
if(TR_DidHit(trace))
{
TR_GetEndPosition(vecPos, trace);
vecOrigin[0] += 0;
vecOrigin[1] -= 0;
vecOrigin[2] -= 0;

or try sm_advanced_laser , it uses differant Beams....
