Measurment of whole field temperature using two-color LIF

Temperature Measurement of Air Flow Using Fluorescent Mists Combined with Two-Color LIF

This study proposes a two-color laser-induced fluorescence (LIF) technique for measuring the temperature distribution of an airflow by spraying a mist of a fluorescent dye. The mist is generated by using propylene glycol, the vapor pressure of which is much lower than that of water, as the solvent of the fluorescent dyes. A supersonic moisture chamber is used as the atomizer for seeding the tra...

Simultaneous whole-field measurements of velocity and concentration fields using a combination of MTV and LIF

A new technique for the simultaneous measurement of velocity and concentration fields is described. We describe here applications in liquid-phase flows, but the methodology can be extended to gas-phase flows with appropriate tracers. In this single-laser, two-tracer approach, molecular tagging velocimetry (MTV) based on the use of a phosphorescent compound is combined with laser induced fluores...

ROOM TEMPERATURE LASER ACTION AND Q-SWITCHING OF F-AGGREGATE COLOR CENTERS IN LiF

Numerical Simulation of an Intense Isolated Attosecond Pulse by a Chirped Two-Color Laser Field

We investigate theoretically the high-order harmonic spectrum extension and numerical generation of an intense isolated attosecond pulse from He+ ion irradiated by a two-color laser field. Our simulation results show that the chirp of the fundamental field can control HHG cutoff position. Also, these results show that the envelope forms of two fields are important factors for controlling the re...
