PCAOM With DPSS Lasers....

[300EVIL]

You know you can make one!

Get some clear gelatin and make it. Yes; with water!

Cut a 1 inch cube of it and place it on top of a plastic walky-talky speaker or a piezo electric disk (disassembled from a tweeter). Put audio into the speaker. Shoot the laser through the Jell-O. Have fun!

Hey James!
Huh, that's cool! Gonna have to try that one sometime. What kind if frequency input is needed into the gelatin?
Thanks!

I have no idea!

Be a pioneer dude!

Take lots of cool pictures and video!

I would suggest using sine waves; maybe more than one frequency. The freqs would depend on the size, mass and spring of the glob of Jell-O.

I'll try it tomorrow. Gotta get some Jell-O. What flavor do they suggest?

Good old cow protein!

Oh, good heavens! Don't tell that to the vegetarians!

Real vegeterians never eat Jell-O!

the origional AOs were 10 mhz quartz crystals immersed in water cells. It works, but I dont know about jello with audio unless your laser wavelength was like, a METER?
or very very low diffraction eff at best ?

I doubt you have anything there over 20 years old. Only the real old digital printers used AOM's. Digital copiers began to surface around 93 and by then they were using modulated diode lasers. I've been in the copier industry since I was 15 and have never seen a gas laser powered copier or printer. My guess is their all long gone.

They were the big 200 page a minute jobs for printing books, and a few early HP laserjets with henes.

OH COME ON!

It's worth a try!

You will at least get a lumia effect!

BTW if you cut a cube of Jell-O and set it on the transducer, the top will be a low pressure node. IOW, it will be able to vibrate more freely than anything below it. If you set a quarter or something like that on top of the cube, it will make a high pressure node, where motion is pretty much zero.

This will probably be a better way to get standing waves in the Jell-O!

How about integrating the Bragg cell into the laser module? This would greatly improve the performance of DPSS lasers without making them more complicated to the user.

The manufacturer would have to add driver circuitry for the AOM, but the diode driver could instead be simplified, as analog modulation through that route isn't needed anymore.

Since we have representatives from a few manufacturers here, perhaps some of them will snap the idea up. I think this kind of innovative thinking together with improved QA is exactly what the Chinese manufacturers need to put them on par with European and American companies.

What would be the cost of such a laser once they are produced in large quantities and how much more would we be prepared to pay for a green laser with analog modulation like a direct injection laser?
