3.7W Whitelight Ion Laser $1500

[300EVIL]

Not mine but looks good for the price in working condition with PS...

My financial timing is peccable.

My financial timing is peccable.

You and me both... Now watch, as soon as we are flush with cash deals like this won't be available.

Go ahead...smake a card! I would...but trying to beat them down a bit.

What wavelenght(s) light does it put out? What can you use it for? what is its divergence like?

John

Typically, with an ion laser like this, the wavelengths are many, you can use it for anything and the divergence is quite low, not to mention that there is no issue of beam convergence since everything comes out of the laser tube at once rather than post-optics with an RGB etc.

This is from Sam's Laser FAQ:
Argon ion visible lines (8 UV lines and 2 IR lines ignored):
454.6 nm, 457.9 nm, 465.8 nm, 472.6 nm, 476.5 nm, 488.0 nm, 496.5 nm, 501.7 nm, 514.5 nm, 528.7 nm.

Krypton ion visible lines (4 UV and 8 IR lines ignored)
406.7 nm, 413.1 nm, 415.4 nm, 468.0 nm, 476.2 nm, 482.5 nm, 520.8 nm, 530.9 nm, 568.2 nm, 647.1 nm, 676.4 nm.

... and here's a link to that specific page.

I wasn't able to find data on that specific laser just yet.

Realistically, you'll get the 647 red from the krypton, plus 6 or 7 of the argon lines. For sure you'll get 514 green, 488 blue, 496 blue, and the 457 blue.

To put this to good use, you'll need an 8-channel PCAOM. (Plus access to 3 phase power of course.)

For those of you that went to see the Pink Floyd Laser Spectacular back in 2007 in Lakeland, Florida, they had two of these same Coherent Purelights running the show.

Purelights usually do some yellow as well.

676, 647, 568, but not 575. And the main argon lines, and there is a possible 520 or 530.

And while the PCAOM rules, there are other ways to do color control, many of them forgotten in this age of solid state, but I am a old geek.

You mean like a prism on a servo with a pinhole?
