Various ambiguities in re-constructing laser pulse parameters

The key parameters for a light pulse are (i) carrier frequency, which cannot be described or imagined without its state of undulation expressed as its (ii) phase, (iii) carrier envelope that provides the temporal boundary of the field amplitude strength of the undulating E-field. The final parameter is the (iv) state of polarization or the unique plane along which the strength of the E-field gradient undulates. None of these filed characteristics are made self-evident by the fields themselves. We present various experimental results to illustrate our arguments
