<p>H:/dxl/Interwovn/NRPortbl/DCC/DXL/5I 18895_l.doc-2/05/2013 A system and method for controllably chirping electromagnetic radiation from a radiation source includes an optical cavity arrangement. The optical cavity arrangement enables 5 electromagnetic radiation to be produced with a substantially linear chirp rate and a configurable period. By selectively injecting electromagnetic radiation into the optical cavity, the electromagnetic radiation may be produced with a single resonant mode that is frequency shifted at the substantially linear chirp rate. Producing the electromagnetic radiation with a single resonant mode may increase the coherence length of the 10 electromagnetic radiation, which may be advantageous when the electromagnetic radiation is implemented in various applications. For example, the electromagnetic radiation produced by the optical cavity arrangement may enhance a range, speed, accuracy, and/or other aspects of a laser radar system. - ~ 122 114d -- 116 -- ,4--- 124 - 11 4c FREQUENCY SHIFTER OPTICAL -- 12612 H 11 4b 1* ------------- ------------------------- 11 4a 12 RADIATION 112 SOURCE</p> |
