Abstract
The stability of polarization, areas, and number of
self- induced transparency (SIT)- solitons at the output from
the LaF3:Pr3+ crystal is theoretically studied versus the
polarization direction and the area of the input linearly
polarized laser pulse. For this purpose the Vector Area Theorem
is rederived and two- dimensional Vector Area Theorem map is
obtained. The map is governed by the crystal symmetry and takes
into account directions of the dipole matrix element vectors of
the different site subgroups of optically excited ions. The
Vector Area Theorem mapping of the time evolution of the laser
pulse allows one to highlight soliton polarization properties.
