【 摘 要 】

Interaction of few-cycle pulses counter-propagating in an optical fiber is studied numerically via solution of equations for bi-directional fields that are equivalent to the full scalar wave equation. It is simulated how 3-cycle optical pulse of the Ti:Sa laser is gained as it propagates through the field of the pulse on the second harmonic with higher intensity in the telecommunication type single-mode optical fiber. Rise of sixths harmonic is also observable under considered conditions.
