Coherent optical pulses in crystals
- 120 Downloads
Polariton effects on the steady propagation of an optical pulse are studied. It is shown that pulse solutions exist even in the case where the pulse width is sufficiently long compared with the reciprocal of the polariton gap frequency. This suggests that the steady propagation may be realized also in crystals.
