There are two questions I wanted to ask. The first is what substances are used in a maser? The second is how can the wavelength of a laser using a certain substance be determined without physical testing?
I'm digging up some 30 year-old memories here, and I'm not sure that they're right, but I seem to recall that the original masers were ammonia-based. If someone wants to do the math for bandgaps and whatnot, they can confirm or deny that.newbie7.07 said:There are two questions I wanted to ask. The first is what substances are used in a maser?

I certainly remember uvaser in the "Star War/SDI" days.Distinct names have been proposed for devices that emit in each portion of the spectrum, including grasers (gamma ray lasers), xasers (x-ray lasers), uvasers (ultraviolet lasers), lasers (visible lasers), irasers (infrared lasers), masers (microwave masers), and rasers (rf masers). Most of these terms never caught on, however. All but maser, laser, and raser are now obsolete, and the latter is uncommon.
