TITLE: Custom Beam Expander Requesting Lab/Division/Group: 68607 Requisition Number: NB686070-20-01809

Statement of Need The Fiber Sources and Applications Group (68607), NIST-Boulder, develops novel methods of optical time and frequency transfer and frequency-comb based spectroscopy that make use of fiber-laser frequency combs. As part of this work, the group develops fiber-optic based instruments that operate throught the near infrared.

The group requires customized beam expander as part of a free-space optical terminal that couples light between free-space and single-mode fiber and maximizes transmission of light across a free-space optical link. As part of our effort to operate over longer link distances, up to 300 km, we need a beam expander to increase the 1/e^2 Gaussian waist diameter of the beam launched from the terminal from 3 mm to 80 mm, with minimal power loss and minimal phase-front distortion in the launched beam.
