what's a 3392nm IR laser good for?






For a hobbyist, it's useless.

For a researcher who requires that wavelength for their experiment, it's very valuable ;)
 
Always keep in mind that lasers were never intended for the hobbyist. As such, novel laser systems will continue to be developed outside of the visible range to do things such as irradiate a target for thin film material deposition. You know...real science.

I find it very arrogant of anyone to question why a laser exists outside of their need to shine it around their room.

My two cents.

WHAT!!!!!!!




But I'm the center of the universe!





Aren't I?

YOU, my friend, have been replaced...say hello to my little friend, Mr. 3392nm laser.

Well that certainly puts a kink in my plans for world domination.

Imma go outside now, and lick a frog, and find my new identity, (or was that my secret identity?).

Peace,

a lot of those 'weird wavelength' IR diodes are used for gas detection of some sort. I was reading about it somewhere and now I cant find the link....

EDIT: didn't click the link to see that it's a HeNe. Pretty neat!
 
I had several of these IR hene lasers before. Pretty useless for the average joe laser geek. They are used in IR gas absorption spectrometers for industrial emission testing and IR optical lens testers mainly. Surprizingly, they went VERY, very high on ebay. As in over $500 each. Traded two of them for a coherent fieldmaster power meter and a synrad controller box

My buy it now was only $75 each for the first couple i sold too LOL
 
The long wavelength diodes are called quantum cascade lasers... They are rather powerful, but are meant to operate in temp controlled chamber. They can be operated at room temperature about 5um too, but wavelength is STRONGLY dependent on temperature. Here is a picture of one that came from an explosives sniffing tool prototype that never made it to market. The range of this one was 4 to 5um. Note the greenish AR coating and znse window.

How powerful? [smiley=evil.gif] What is the price?
