Anyone interested in 493nm 200mW single mode?

Lol imagine if you buy this diode and you accidently kill it due to static electricity :p then you are absolutely f**k*d lol:horse:

You could always buy 2 and send them off to a pro-builder and tell them that if they don't kill the first one the 2nd one is their reward :D

Such a pretty blue colour :drool:

Ahhh i see where we're going here ;)

So overdriven by company terms would yield ~493nm, overdriven by OUR terms... What a nice shade of cyan we'll have!

Edit: if they do go down, I'd overdrive one, and UNDERdrive the other, 483nm sounds pretty good to me, even in low powers.

About how much was the Argon 488?

I bought mine for ~$150. Check dave's sale, he seems to sell them at the best prices. Link

Dave's drivers are too big for me! :D

Here's the thing, if you go look at the prices of a 445 at Nichias site you will see similar prices, but an OEM manufacturer will get these very cheaply. Hopefully they will end up in a relatively inexpensive product that we can rip open and harvest.

Which products for" biotechnology and other applications for flow cytometry" should we start looking in? :can:
 
I wasn't aware that such products exist...

They are selling a BD diode at 5mW for 1.435.00€ (~1.700.00$) :wtf:

Thorlabs knows their demographic, which is university and general science laboratories. Scientists generally don't have a problem blowing their grant money on expensive parts, and Thorlabs doesn't have a problem collecting that grant money through inflated prices. They know that these same scientists are used to paying $$$THOUSANDS$$$ for a laser, no matter what type or manufacturer. That's just how it is in the world of serious scientific research.

OMG they stole the light from my argon and put it in that little diode!
 
Man... I winder if there is a way to make your own diodes. I know the actual light emitting part is less then... half a millimeter. Would having a bigger piece just not emit light?
 
slightly bigger would, sizes hobbyists work with however, they will not emit light. Plus the process of growing the crystals flawlessly and all... not many hobbyists can afford the machinery.
 
And then there is cutting the facets on the diode face... =p The whole process would probably be more expensive than an exotic diode :\
 
You have to grow the crystals first, doped eith the right chemicls. Then cut them to the exact size. I believe the length of the crystal determines the wavelength it lases at so has to be the right length to work and these things are less than a mm long.

Plus as Wolfman says the ends of the crystal need to be polished, i think they cleve them with a sheering action to do this and trim the length.

Then you need to make an electrical connection, they have gold foil on the crystal for this, i dont know it its vacuum deposited or what. Then they bond them to the die with gold plating using (i think) indium foil. And then you have to weld the wires to that.

In short, I doubt it's something anyone could do at home. It would be easier to get a boule from a ruby and grow a ruby laser crystal, you can get the boules to seed the crystal for a few hundred dollars off eBay.
