Hi! Here you can find what happened with my 405nm laser.

After some time collecting the parts, I finally was abble to assembly a 650nm laser within this host and driver!

I don't know the current of the driver, but I put a LOC on it and is very powerfull.

----------

Here you can see the housing, originally it was made for 3.3mm LD, so I drilled a new 5.6mm hole into it.



Here, the LD press fitted in the place, It's a long open can LD.



And the housing + driver assembled. See a enameled wire, that's the '+' of the driver, since the driver is case positive and the LD is case negative, it's needed to isolate one from another.




Here the empty host, is a standard "(SD)Laser 303".




And now, the host assembled and working!




Since I got the lens from a 1mW red key chan, it's a terrible lens, so here is the "dot":



And, unfocused:



Melting insulation tape:



A beam shot:



And the laser besides with my 250mW red:




The worst thing was lock the module insyde the host, with the switch perfectly alligned!

Thanks! :thanks:
