On an ESFADOF edge-filter for a range resolved Brillouin-lidar: The high vapor density and high pump intensity regime

Optics in Remote Sensing

“…But an especially promising approach is an excited state Faraday anomalous dispersion optical filter (ESFADOF) [20][21][22]. Basically, an absorption cell containing an atomic vapor is placed between crossed polarizers and in a strong magnetic field.…”

Comparison of three technique of Brillouin lidar for remote sensing of the ocean

“…It can be used for the real time measurements of sound speed in the water [4,9], temperature of the water [2,3,10,12], salinity of the sea water [3], and attenuation coefficient of the water [13]. Also, it can be used for detecting submerged object [6].…”

Electrodeless-discharge-vapor-lamp-based optical atomic filter

“…1). In the past two decades, much effort has been focused on improving the transmittance of the ESFADOF, and there is limited progress on how to simplify the system effectively [7][8][9][10].…”
