The present invention provides systems and methods using a temporal-frequency sensitive receiver to detect laser light that is scattered by an oscillating object, thereby allowing remote monitoring of the object's position and movement.

Laser frequency stabilizer using transient spectral hole burning

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.

Programmable frequency reference for laser frequency stabilization, and arbitrary optical clock generator, using persistent spectral hole burning

The present invention provides a means to generate a Raman-shifted output from a pump laser source. Multiple embodiments all provide a manner of producing an off-resonant, continuous wave, Raman laser by using a pump laser source having a low power. This is accomplished by using a Raman medium within a cavity having a high finesse.
