“…The ESFADOF is the approach that we are following. For completeness, we will briefly discuss the key ideas, for a more detailed characterization and discussion we refer to our earlier publications [10-12, 14, 15]. Briefly speaking Faraday anomalous dispersion optical filters (FADOFs) and their excited state counterparts ESFADOFs consist of an atomic vapor cell placed in a homogeneous magnetic field between two crossed polarizers.…”

“…As ESFADOFs exploit atomic transitions between two excited states, an external pump source populating the lower ESFADOF state is necessary. Specifically, we investigated the 5P 3/2 → 8D 5/2 transition in Rubidium as the ESFADOF transition [12, 14]. Our results indicate that an edge filter based on this transition is possible.…”

Temperature profiles of the ocean are of interest for weather forecasts, climate studies and oceanography in general. Currently, mostly in situ techniques such as fixed buoys or bathythermographs deliver oceanic temperature profiles. A LIDAR method based on Brillouin scattering is an attractive alternative for remote sensing of such water temperature profiles. It makes it possible to deliver cost-effective on-line data covering an extended region of the ocean. The temperature measurement is based on spontaneous Brillouin scattering in water. In this contribution, we present the first water temperature measurements using a Yb:doped pulsed fiber amplifier. The fiber amplifier is a custom designed device which can be operated in a vibrational environment while emitting narrow bandwidth laser pulses. The device shows promising performance and demonstrates the feasibility of this approach. Furthermore, the current status of the receiver is briefly discussed; it is based on an excited state Faraday anomalous dispersion optical filter.

“…Due to its high transmission, large field of view and fast response time, FADOF is useful for a lot of applications, such as freesapce optical communication and Brillouin lidar [4][5]. Ground-state FADOF (GSFADOF) has been widely used because that it is convenient to achieve very high transmittance.…”

An excited-state Faraday anomalous dispersion optical filter (FADOF) has been demonstrated, which utilizes a rubidium electrodeless-discharge-vapor-lamp rather than an external pump laser. When the lamp is turned off, the lamp-based filter can be treated as a ground-state FADOF. The compact lamp based FADOF holds promise for realing a frequency-fixed diode laser systems (such as a 1529 nm laser for optical communication application) and a multi-frequency filters.

Faraday anomalous dispersion optical filter with a single transmission peak using a buffer-gas-filled rubidium cell

et al. 2012

View full text Add to dashboard Cite

A Faraday anomalous dispersion optical filter (FADOF) with a single transmission peak is achieved by using a buffer-gas (argon, 2 Torr)-filled rubidium cell. At room temperature, the transmission is 0.2% and the bandwidth of the transmission peak is 0.65 GHz. At a temperature of 63° C, the transmission rises to a maximum of 30.6%, with a bandwidth of 1.41 GHz. This FADOF may replace the use of interference filters or virtually imaged phased arrays in imaging modalities.
