heres stage one of my home made red did not know it was such a bitch to line up four lasers but its done now took me all day to get them right they are set up like this # but square through a pbs cube no other optics used other than the axiz glass three element ones on the diodes ,did not want to ruin the divergence, so i now have a 5x5mm output @0.4mrad cant check the output power as i dont have a meter but may make it to uklem2 and hope somone can help with that,any advice is welcome to have i done this right to get best power out i dont know if the hash configeration is good or nothave left room on it to expand to six lasers at the moment i am drive mitsubishi at 300ma so am hopeing for at least7/800mw output,its all going in a rgb i am making should have brought a blue from bridge but my laptop broke to the funds went into replacing that but i did get a cni 200mw green one month old of ebay for £150 ,saving hard for blue hope to have it by the winter .
