  • Abstract
    A passive Fraunhofer-wavelength atomic filter in the spectral region of minimum seawater attenuation is reported. Signal light at 460.7 nm is strongly absorbed by strontium atoms contained in a heated vapor cell. Collisions with rare gases transfer population into the Sr(5 p3Pj) level, which subsequently emits 689.3-nm photons. Up to 45% photon conversion efficiency was recorded. The strontium filter exhibits a 50-μs decay time and a single noise passband
