6W Triple diode laser

Re: Build: Tri-Diode laser Est. 5.6W

For many optic applications, I use dental
UV cure adhesive. It cures using a 405 nm
laser and no fumes to coat lenses.

I should try that out next time! How much power does it take to cure it?

why do you have to use such old epoxies, its taking to long .. :na:

I have 24h epoxy, 1h expoxy and 5 min epoxy. 5 minutes is too short for this

so hows the build coming along now? waiting in anticipation :O

Alignment never gets easier

I thought it would be now that I know what I'm doing, but apparently not.

I have some large chunks on time this weekend when I can sit down and do some alignment for hours. Apparently this one is going to take just as long as the last one, it's really tedious work.

Wave plate has been aligned and glued down. Diodes have been aligned horizontally.

Pre-alignment dot. The bottom beam will me moved up to perfectly overlap onto the top dot.

Cube and mirror, you can also see how I mounted the wave plate directly onto the lens barrel to save space.

I like that close up shot of the PBS!

Yeah, you can even see the piece of lens paper fluff still on it

What kind of camera are you using?

Some photos were taken with a Nikon D5000 (with an 18-55 I think?), the cube photo was taken with a Nikon coolpix L110.

Those are some nice cameras! I cant wait until this laser is fully operational. What are you running those diodes at to align them?

Re: Build: Tri-Diode laser Est. 5.6W

What are you running those diodes at to align them?

200mA to do the dot alignment 1-2A to do the beam alignment (depends on time of day)

Where do you get your optics from?

 

[ARG]

Re: Build: Tri-Diode laser Est. 5.6W

I buy lots of cheap optics on ebay and use them in builds when I can. If you keep your eye open you can score some great deals, a while ago there was some NIB Edmund mirrors that normally sell for 50$ for 2$ each, the transmission on them is phenomenal.

For the things I don't already have (or have but not the best transmissions) I buy from Rob at Stanwax. Lots of budget optics and they perform amazingly for the price.
Stanwax Laser entertainment laser services, parts & laser projectors.
I highly recommend them, great service.

Aligned the cube today, just the mirror left on the blue diodes

Fantastic work you do. Would you have a parts list, for this and the dual diode blue, very specific with a vendor list for those of us that could buy a little at a time then ship to you for fine tuning?. Or is that a dumb idea?.

You can get the diodes/lens' from DTR, Optics are on ebay, drivers from lazerer, and the host is from Mrcrouse.
