Has anyone attempted to build a maser before?

What makes you affraid of microwaves? They arent more dangerous than light at equal power levels, and usually not that easy to focus on a small area due to the larger wavelength.

From Biological Effects of Radiowave Transmissions (condensed) :

the main objectively measurable hazard of microwave radiation is injury to the eyes, especially damaging at frequencies above 800 MHz. Since the lens of the eye does not have an adequate vascular system for the exchange of heat, even a slight rise in temperature can cause protein coagulation, and opacities in the lens may form. This may already be defined as a cataract, however in clinical practice the term cataract is normally not used unless the opacity has progressed so much as to interfere with visual acuity. Experimentally cataracts in animals develop after exposure to power densities above 100 mW/cm². Missing was exact information on duration. It is safe to assume a short pulse was sufficient , since most researchers feel strongly that repeated exposure of the lens to lower doses of radiation can result in accumulation of injury.

well i just so happen to have a book on 'masers and lasers' <---actual title
i will read through and post any useful information here for mfo and everyone for that matter. expect delay , as i am house-sitting for next week, but i will get to it.

i know microwaves enough to not want to play around them in high power beams form (not without a complete shielded suit, at least :p

well HIMNL9, its a good thing you listen to your intuition. i would be willing to bet that you use a cell phone, don't ya' ? if you would like to know how microwave radiation is effecting you and everyone else around.....

lets start with cellular phones , info here
on to the findings from OSHA ,FCC , EPA here
more analytical evidence from spain here
if any of you get to play around with masers , do it in a SAFE and CONTROLLED manner. :scared:
