Spatial phase control and applications of highorder harmonics

We present experimental results of control of high-order harmonic wave-fronts. We have reached a spatial phase with average distortions of ?/7 at 32 nm when controlling the fundamental laser beam wave front. We app...

Temporal-spatial dispersion analysis of finite element method in implicit time integration

is used as well as the consistentnmass matrix. The temporal-spatial dispersion relationships are derived in the closed form and analyzed due to errors in numerical wave speed of propagation of harmonic wave. Based...

Propagation and interference of thermal waves in turbulent thermal convection

We report investigation of thermal waves in harmonically modulated turbulent thermal convection in a Rayleigh-Bénard cell. We probe the thermal waves waves and describe their behavior in terms of models that explai...
