Tis gonna be a dual 445nM laser thing (I dont even know it should be called, laser spotlight? rifle? mess?)
That part is the battery holder (6V 12A/H sealed lead acid), there is a steel bushing and a 5/8" rod along with 1/4" rods as supports, they will connect the battery to a laser head (not made yet), reason I made it as it is, is because the battery compartment wieghts 12LB total, and the head will wieght around the same, so I didnt want it loose and squirming around. Its far from done though.
the head will have 2 rods, each housing a 1.5W 445nM laser. Ill post more pictures when I finish building it.

can we be blessed with a pic of your silicon die or laser tube itslef, 1.5 W @ 445nM is too cool...
Eh.. I dont know if my camera can zoom that well onto the chip itself, but heres a shot at it: seems the bond wires came up okay, the die is ontop of that brass plateform inside.
Diode running without collimating lens:
It is a 5.6MM can diode, (InGan die probably) a projector was released with 24 of these things inside, they where meant for under a watt, but they have no problem handling exess power (some people even pushed them to 2W) these are 445nM multi mode diodes. lots of power in such a small package, so they need heavy heatsinking for any decent run time.
google A-140 diodes Patrick, there is quite a bit of information on them, they are indeed powerfull.

One of them days, Tater.
Spent yesterday at this massive 6 alarm industrial fire. It destroyed a city block and damaged houses on adjacent blocks on all sides. 24 hours later, there are still firefighters on scene.

EDIT: I'm going to find a screen capture later on, but the fire was so hot that it appeared the zinc on the outside of the galvanized steel siding was beginning to burn in big patches, resulting in areas of blinding yellow/white flame on the siding.
