摘要

我们报道了一种含杂质原子晶体中二次谐波产生的类孤子体制的研究,该晶体具有量子跃迁,相对于基频激光脉冲是准谐振的。考虑了相速度和群速度的不匹配。结果表明,准谐振杂质一方面会导致产生效率的降低,另一方面,它们能够为双频孤子状态的实现创造条件,这在没有它们的情况下是不可能实现的。

Soliton Regime of Second Harmonic Generation in the Presence of Quasi-Resonant Impurities

We report a study of a soliton-like regime of second harmonic generation in a crystal containing impurity atoms with a quantum transition, which is quasi-resonant with respect to a laser pulse at the fundamental frequency. Mismatches of phase and group velocities are taken into account. It is shown that quasi-resonant impurities, on the one hand, lead to a decrease in the generation efficiency, and, on the other hand, they are capable of creating conditions for the implementation of a two-frequency soliton regime, which is impossible in their absence.
