Abstract
The specification describes an improved seed laser source for high power MOPA applications. Improvement is obtained by modulating the seed laser with a broadband noise function, for example, a Guassian noise function. A broadband noise function is one in which, in contrast to a sine wave function for example, has an RF spectrum with a bandwidth comparable in value to the mean frequency. Use of a broadband noise modulator allows effective tuning of the output of the modulated laser.
