Title: Stable, narrow spectral linewidth, fiber-delivered laser source for spin exchange optical pumping

Abstract

Disclosed herein are example embodiments for providing high power, narrow linewidth, high-stability laser sources. Particular embodiments are adapted for use in spin exchange optical pumping (SEOP). One example system comprises an array of laser diodes; a beam twister positioned to receive individual beamlets from the array of laser diodes, the beam twister being configured to rotate the individual beamlets from the array of laser diodes and produce rotated beamlets; one or more collimating lenses positioned to receive the rotated beamlets produced by the beam twister and produce substantially collimated beamlets having a divergence angle; a spectral-line-width-reducing element positioned to receive the substantially collimated beamlets from the one or more collimating lenses and produce spectral-line-width-reduced beamlets; an optical fiber; and one or more focusing lenses positioned between the optical fiber and the spectral-line-width-reducing element and configured to receive the spectral-line-width-reduced beamlets and focus them into the optical fiber.
