    Default home made 800mw red

    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 .

    Nicely done. Do you have a photo of the dot, and do you plan on reducing the beam diameter?

    Also, can you please write in sentances, with punctuation?

    i flunked english at school due to being very ill as a kid and just did not catch up,you want to see the state of my writing its bad,but i make up for
    it with other skills , (so dont be to hard on the lad), lol. i dont plan on reducing the beam size the galvo mirrors can just cope with it, and using a lens to reduce it just ruins the divergence. hi dave bigger is better i might make another and combine the two, i have only basic hand tools to build this with and have had a lot of trouble getting beams lined up far field,its my first attempt at somthing like this and very happy so far, and yes they are robin's drivers ,they work very well ,more pics coming soon as i put it back together again, pulled it apart as i want better beam line up ...........

    please line me out on your red laser solution, supplier or parts and pieces I am looking around and combining 2 650 nm 70-110mw diodes is not quite giving me quivers I just bought 3 25-50 watt 808nm fiber pump lasers and have big plans for them red seems a biotch to produce cheaply green no problem with right crystals mounts optics heating cooling and power supply concerns. also I have a tested 176 IQ but am a serious OCD run on sentence writer and seriously dyslexic but I fix most my transpositions and edit out so do not let anyone run you down your setup speaks wonders about your skill set!!!!!!!!!!!!
