BROADBAND MID-INFRARED SOLID-STATE LASERS Broadband Mid-Infrared Lasers

A survey of broadband Co2+and Cr2+-based lasers is presented. These mid-IR sources, operating in the very interesting “molecular fingerprint” region between ∼1.6 and 3.5μm offer the broadest bandwidth from all solid-state vibronic lasers. The emphasize is made on Cr2+-doped lasers, which have not only the widest and the highest gain, but also operate at room-temperature and produce the shortest...

Broadband mid-infrared polarization rotator based on optically addressable LCs.

This work proposes a mid-infrared polarization rotator that incorporates a twisted nematic liquid crystal (TNLC) cell with a photo-controllable alignment layer. The TNLC device with a sufficient phase retardation can act as an achromic polarization rotation device over a wide wavelengths range and thus can rotate the polarization of a mid-IR laser beam. The photo-alignment technique enables TNL...

Intensity tunable infrared broadband absorbers based on VO2 phase transition using planar layered thin films

Plasmonic and metamaterial based nano/micro-structured materials enable spectrally selective resonant absorption, where the resonant bandwidth and absorption intensity can be engineered by controlling the size and geometry of nanostructures. Here, we demonstrate a simple, lithography-free approach for obtaining a resonant and dynamically tunable broadband absorber based on vanadium dioxide (VO2...

ISOGAL Survey of Baade’s Windows in the Mid-infrared

The ISOGAL mid-infrared survey of areas close to the Galactic Plane aims to determine their stellar content and its possible bearing on the history of the Galaxy. The NGC6522 and Sgr I Baade’s Windows of low obscuration towards the inner parts of the Bulge represent ideal places in which to calibrate and understand the ISOGAL colour-magnitude diagrams, which are more difficult to interpret in h...
