Infrared radiation generation at forced combination scattering

Infrared Edge Radiation Beamline at Aladdin

An infrared beamline has been constructed at the 800 MeV electron storage ring, Aladdin. The beamline is located downstream of a short straight section, where it collects edge radiation produced by electrons exiting and entering the bending magnets at the ends of the straight section. Measurements at wavelengths of 1–5 μm suggest that the edge radiation is brighter than standard synchrotron rad...

I . Tunable infrared generation by Raman scattering 1 1

Parametric generation of tunable infrared radiation in ZnGeP2 and GaSe pumped at 3 I.Lm

Traveling-wave parametric generators with angular tuning with the use of ZnGeP2 and GaSe crystals pumped by 100-ps pulses from an actively mode-locked Er laser (A 3 ,m) are reported. The continuous-tuning range achieved was 4-10 /im (ZnGeP2; length, 12 mm) and 3.5-18 ,um (GaSe; length, 12 mm) in a type-I interaction, with a quantum conversion efficiency of a few percent. In the case of ZnGeP2 (...

Generation of coherent and tunable ultraviolet radiation by scattering processes

Tunable, coherent radiation in the ultraviolet region has been generated by stimulated Raman scattering, by anti-Stokes Raman lasers, and by frequency-mixing processes based on nonlinear polarizabilities of atomic and molecular systems. Present progress in the development of these laser-driven sources is reviewed, with examples of available systems and their characteristics. Applications in spe...

Scattering reduction at near-infrared frequencies using plasmonic nanostructures.

Novel fabrication, detection and analysis approaches were employed to experimentally demonstrate scattering reduction by a plasmonic nanostructure operating at 1550 nm. The nanostructure consisted of a silicon nanorod surrounded by a plasmonic metamaterial cover comprised of eight gold nanowires and was fabricated by a combination of electron beam lithography, focused ion beam milling and dry a...
