Maser beams and absorbtion...
« on: 05/06/2004 13:01:32 »
I am very interested in maser beams and their qualities. Short sharp blasts are most interesting for my potential purposes. But absorbtion sheilds are needed and I don't know about what can repeatedly absorb them. Do you fellows know anything? I saw ads for laser guns for rabbits in the eighties. In an English mag.

Bren,
MASER is an acronym that sounds like LASER and is the same thing except the M stands for microwave.  In other words, it is a device that generates coherent microwaves.

I don't know much about them, but they are not small, and they are not cheap like lasers.  Absorption materials for microwaves are also more tricky than for light because of the nature of the waves.  Again, not small.

The only application that I'm familiar with (and I know there are others) was a research maser that shot pulses straight up and measured the returned signals in order to study atmospheric phenomena in the mesosphere and lower ionosphere.  It wasn't quite like radar, and I don't remember exactly why they had to use a maser.  I do remember that making sure there were no airplanes over the system was a big deal.

What do you have in mind?  Maybe I can help more if I know some details.  You can e-mail me directly if you would rather.
