This is a full video on how I assemble another powerful laser. Sorry if I used bad explanations, Any questions please ask. I used a DVD dual layer laser from an Asus Light scribe capable burner. The laser diode can do about 300 mw peak, its driven to 200 mw or so now. the lens in the video is not the right lens, it is for a DVD burner and not a pointer, this means that the laser cannot evenly produce a beam at range without rings and a fogging effect ” loss of laser output power ” when I get the correct lens I will mount it in and shoot a demo video on this laser. I also used a laser driver from a 5 mw green laser. Since it runs a pump diode at much higher mw it really put out some power for the red laser diode, the driver is at stock settings, no need for pot modding the driver before use on a dvd laser ” be careful when trying this all drivers are NOT the same.
