Abstract
A MASER (Microwave Amplified Stimulated Emission of Radiation) emitter is fabricated of thin film components, including a thin film of nitrogen-implanted, epitaxial crystal diamond. The MASER elements can also include a controllable Q-switching layer and be arranged in a thin panel, phased array to generate a single beam of coherent, mode-locked, continuous wave MASER radiation.

A MASER emitter capable of outputting coherent microwave energy, comprising:
- a first dielectric polymer resonator layer;
- a second dielectric polymer resonator layer;
- a gain medium comprising a thin film epitaxial layer of nitrogen-implanted crystal diamond,
- a Q-switch CCD controlled layer of nematic molecules located adjacent the gain medium, wherein the gain medium and the Q-switch are located between the first and second dielectric polymer resonator layers, said Q-switch being controllable between a high Q factor setting and a low Q factor setting;
- an LED layer that outputs light that passes through at least the first dielectric polymer resonator layer to pump photons into the gain medium at a level sufficient to cause coherent microwave emission from the gain medium in continuous wave mode when the Q-switch is set to the high Q factor setting.
