np i also thought about taking apart the ir headsets that they mention on that page and maby trying it with 2 of them. a data system would work also i was just trying to get some sortive laser communications system that i can build for not much money even if i have to use one that is already built but have to modify to do it.

I have a Heathkit/Zenith laser and receiver from 1985 that did exactly what you describe. Also have the manual and instructions from the guy who built it at home. Still works fine.

nice if you are selling i might be interested at some point down the road. im a little strapped for cash right now. does everything still work correctly?

I dug out my copy of the laser cookbook to double check the information you need is in it...

http://www.amazon.com/Laser-Cookbook.../dp/0830693904

It was released in 1988 but it has the relevant circuits and information. Although I would probably substitute a modern diode driver. It noted even a red led (with clear shell) can be used as a receiver for red wavelengths. The audio amplifier after that.

I doubt Bob was interested in selling his, I look forward to seeing it in his Museum some day.

Adam's right, not for sale. But the circuit is simple and cheap. I recommend the "Laser Cookbook" as described above.
