New 2w 808nm Handheld Laser

[billg519]

The weather was lousy on the weekend, so I decided to make up a nice 2 watt handheld using a snoctony c-mount diode that I had not yet done anything with. This laser is 6 3/8 " long by 1" diameter. It is machined from 6061 aluminum stock. I fluted the barrel to give it a different look from my usual cylindrical barrel. I then gave the aluminum parts a clear anodize, providing scratch resistance and a smooth feel. An aixiz glass lens is fitted into my own brass lens holder and focusing assembly. The beam will collimate to a tiny burning point about 2" from the laser. (Adjustable, but without adding slow axis collimation the output is bar-line at 12" distance.) This laser is a great little close range burner.

Diode : Snoctony 2w 808nm c-mount from ebay
Regulator : 2 x DX 1400ma regulators
Battery : 1 x 18650 lithium
Host : C-mount head and barrel machined from 6061 aluminum rod stock, lens assembly is brass.

Here is a photo of the laser.

Nice, how much did this cost to build?

thats so awesome! ;D i want one!

Thats extremely beautiful!

Very impressive. [smiley=tekst-toppie.gif] How long did it take you to make it. [smiley=cool.gif]

I need about 3 hours on the lathe and mill to make the parts, the another 1 1/2 hours to anodize the aluminum parts. Then I take it home and spend another 2 hours putting it all together and testing it.

Diode is $95 USD on ebay. Total cost of parts is about $110 USD.

I am quite happy with how this laser came out. It is an agressive burner.

Very impressive. I like when people use C-mount, TO-3, HHL and others to fabricate their homebuilts. It requires ingenuity to use these types of diodes.

Would you possibly be interested in selling one of the beauties? :

would you consider building again? (for me lol) also you can get 3W c-mounts for $70 on ebay now ;D

awesome! take some videos of its burning power if you can!

 

[Ace82]

NICE!

That's quite awesome.  I especially liked the woodburning clip; that's a heck of a lot easier than using a woodburning iron.  

How effective were those glasses? With 2W of power, it seems as though they would need to be spectacular.
