Near-infrared to visible upconversion imaging using a broadband pump laser

Autor: Demur, Romain, Garioud, Renaud, Grisard, Arnaud, Lallier, Eric, Leviandier, Luc, Morvan, LoÏc, Treps, Nicolas, Fabre, Claude

We present an upconversion imaging experiment from the near-infrared to the visible spectrum. Using a dedicated broadband pump laser to increase the number of resolved elements converted in the image we obtain up to 56x64 spatial elements with a 2.7

We demonstrate a robust and simple method for measurement, stabilization and tuning of the frequency of cw mid-infrared (MIR) lasers, in particular of quantum cascade lasers. The proof of principle is performed with a quantum cascade laser at 5.4 \mu

We report on the design, realization and testing in pulsed amplification regime of a double-cladding, large mode area, polarization maintaining, solid core photonic bandgap fiber with Yb-doped core obtained from a Sol-Gel -made material. A specific h
