This is a 50mW 680nm laser built in a custom Ehgemus host. Great for wavelength collectors who want something close to that Ruby line! The really nice part is that the host is a custom job by Ehgemus with a black and gold color scheme. The gold accents are brass rings. Let no one say I sold them something claiming it was actual gold lol. With that said I believe this is a very elegant laser and would be a great fit for anyone's collection. I don't have a 660nm laser at the moment but I should be making one soon and I can try to get a comparison shot between them. This laser looks different than 660nm though no doubt about it.

My asking price is 150 shipped! If you think that is too high PM me with a reasonable offer. Also if anyone wants to buy this WITH my 520nm laser I have for sale PM me because I want to work out a deal with you so you get a good price for both.

Why am I selling this? Well my super secret project is expensive. So I need to sell what I have to make way for what I don't.

Re: 30mW 685nm Laser For Sale! Uncommon Wavelength!

Itty Bitty Bump! Whoever buys this I will throw in a 660nm diode also. Lots of red :)

I always loved this diode.

Good luck on the sale!

This truly is a wavelength that you need to see in person to respect its "dry" color.

Interesting wavelength for sure! I haven't seen anything past 660nm before...

Yes it is, and thanks for saying 680, I have corrected the title to reflect this....not sure why I thought 685. Also of note: I LPM'd it and it does 47mW STABLE. Like after hitting 55 or so it falls slowly to 47mW and SITS there. So I have updated that as well.

It is a great little laser and the only red laser I own.

yeah, they made it into a 9mm to make it have as large a surface area as possible, to give it better cooling/a higher equilibrium temp. it also has a microlens in front of the emitter to help with the divergence and beam core. its a nice little laser. I'm driving mine more modestly, but I rigorously tested that one. they're pretty tough for old style single mode lab diodes.

With it being 50mW I might try to just have two more of these hosts made and make some output 635's and 660's.

You may have thought 685nm because that's what is says in your signature. Plus, free bump:beer:

Where did you find a 50mW diode? Thorlabs?

I'm interested as I've only seen the 35mW 685's on eBay.

It's a 30mW diode. It's overdriven just a bit by the driver.

If I recall it was a 109mA LM1117 driver and it's rated at 90mA typical for the diode. I cherry picked two based on their test specs. It's a really tough cookie. It's an awesome lab quality diode for those who like deep red.

It is 50mW with 3-element. With Acrylic it should be even higher :beer:
