Raman-based Distributed Temperature Sensors (RDTS) allow performing spatially resolved (1 m) reliable temperature measurements over several km long Optical Fibers (OFs). These systems are based on the temperature dependence of the intensities of both the Stokes and anti-Stokes components of the Raman back-scattered signal. One of the specific issues associated with RDTS technology in radiation environments...
We report on generation of strong-field-ionization induced free-space air lasers and explore their applications in remote sensing and molecular physics.
We experimentally investigate gain dynamics and temporal characteristics of a free-space nitrogen laser pumped by circularly-polarized femtosecond laser pulses based on the pump-probe scheme.
We report on the generation of coherent N2+ emissions in a plasma string driven by two-color laser fields and measure their temporal structures. It is confirmed that the coherent emissions originate from seed-injected amplification.
This paper presents an investigation on the fluorescent properties of semiconductor CdTe quantum dots (QDs) self-assembled on the surface of PVP (polyvinylpyrrolidone) capped silver nanoparticles (NPs) film by ligand field effect under the two photons excitation of 800nm femto second laser. A significant enhancement by 4.5-fold in the integrated fluorescence intensities, red shift of fluorescence...
