The circular-polarization phase-meter

The circular-polarization phase-meter.

A new method to measure the carrier-envelope phase (CEP) of a strong few-cycle laser pulse is introduced. The new concept relies on above threshold ionization (ATI) in circularly polarized laser fields and allows for CEP tagging every single laser pulse generated in few-cycle laser systems at multi-kHz repetition rates. The implementation of the new method is described and discussed quantitativ...

A New Circular Polarization Metamaterial Ferrite Phase Shifter

In this paper, a new X band Metamaterial (MTM) based ferrite phase shifter is presented. The phase shifter is excited by circular polarized wave base on combination of TE10 and TE01 modes in a square waveguide. In order to synthesize negative refractive index metamaterial (NIM), negative permeability of ferrite slabs in extraordinary mode is mixed with the negative permitivity of printed period...

Anisotropy-dependent circular polarization spectroscopy

We have experimentally investigated the anisotropy-dependent circular polarization spectra of the Cs 6sS1/2→6p P3/2→10s S1/2 double-resonance transition in the presence of Ar. Satisfaction of doubleresonance condition, achieved by use of a two-photon two-color pulse laser excitation scheme, was monitored by measurement of the intensity of the 9pP1/2→6s S1/2 cascade fluorescence at 361.73 nm.
