High stability PM YDFA

BACKGROUND:

NIST research is focused on developing next-generation optical tools for laser frequency comb spectroscopy.

PURPOSE:

The work in the generation of optical frequency combs requires state-of-the-art high-power optical amplifiers capable of amplifying broadband optical signals from 0-10 mW up to 2000 mW.  In addition, it requires high stability and pulse fidelity and a short optical path length with high path-length stability as well as linear polarization.

To achieve the needed stability for the NIST application, a set of specific construction specifications are laid out.
