title: Two-photon absorption dispersion spectrometer for 1.53 μm eye-safe Doppler LIDAR.
abstract: Based upon resonant two-photon absorption within a rubidium cell and 780 nm pump light, a birefringent medium for 1.530 μm is induced that changes rapidly with frequency. The birefringence is exploited to build a spectrometer that is capable of measuring the Doppler shift of scattered photons.
