Abstract
A method and apparatus for illuminating a Bragg cell employ a laser which is directed at the Bragg cell with the focus of the laser beam being disposed outside of the Bragg cell, such as immediately preceding the leading edge of the Bragg cell or the crystal containing the Bragg cell. A spectral analyzer with a Bragg cell disposed therein and operated in this manner has a significantly lower noise background thereby decreasing the lower dynamic limit of the analyzer.
