Abstract
Techniques for stabilizing a laser ( ) at a selectable frequency include splitting an output beam from an electrically adjustable laser into a first beam ( ) and a second beam ( ). The second beam is transmitted through a modulator ( ). Then the second beam is transmitted through a spectral hole burning material ( ) onto a detector ( ). The laser is electronically adjusted in response to a detector output from the detector which senses the changes in the modulated second beam after it passes through the spectral hole burning material.
