The work of this program is divided broadly between two main activities. The first is to obtain a more complete understanding of the physics governing the operation of the FM and super-mode lasers. The second is concerned with improving the techniques for coupling the modes of the FM laser and finding more efficient means for full power supermode conversion of the FM signal to a monochromatic output. An FM modulator was designed and built for incorporation into the laser cavity which is approximately twenty times as efficient as the modulator used successfully in all previous FM experiments. This modulator will permit work with lasers having many more oscillating modes than was previously possible. An external modulator was designed to be used for supermode conversion. This modulator is expected to have ten times the modulating capability of the previous super-mode modulators, allowing work with much higher power lasers. Attempts were made to find alternate techniques for obtaining substantial power at a single frequency.
