Carrier-envelope phase of an elliptically polarized mid-IR light bullet

For the first time, the formation of a mid-IR single-cycle light bullet during propagation of a femtosecond laser pulse with an arbitrary initial polarization ellipticity of the light field has been experimentally and numerically investigated. It is established that the polarization ellipticity determines the effect of the carrier-envelope phase on the nonlinear-optical interaction of the light bullet with the medium.
