Abstract
A device for emission of electromagnetic radiation comprises a source of atomic particles and a collector disposed to receive atomic particles from the source. The collector comprises an emission medium, the medium comprising a crystal having a spatial dimension in the range from about 10 nanometers to about 50 micrometers, wherein the emission medium has the capability to generate opposing charge pairs upon absorption of atomic particles from the source and to emit electromagnetic radiation upon recombination of the pairs. The emission may be via spontaneous emission or, in certain embodiments, by stimulated emission. A laser assembly comprising this device, and methods for making the device are also presented herein.
