Master Oscillator Techniques for 10 micron Radar.

Abstract

The objective of this program was to investigate the feasibility of using electro-optical coupling modulation of a CO2 waveguide laser to obtain a frequency chirped optical signal for application in 10 micron imaging radar. This AM technique combines the advantage of a relatively high modulation efficiency with a wide bandwidth, independent of the gain profile and the free spectral range of the resonator. The use of a wideband waveguide system is for the purpose of displacing the oscillator spectrum relative to the active line of a post-amplifier such that one chirped AM sideband is effectively isolated.
