非共振微波场驱动情况下的简并量子拍频激光器

Degenerate Quantum--Beat Laser Driven by a Non--resonant Coherent Microwave Field

本文讨论了被非共振微波场驱动的三能级原子系统在无粒子数反转时所表现的激光增益以及在无自发和受激辐射时所表现的光学吸收两种物理现象以及产生的条件。

A single lasing mode by a three-level atoms with two levels(closely spaced)driven by a non--tesonant coherent microwave field can show gain without popula-tion inversion or optical absorption without spontaneous or stimulated emission.In the paper the two physical phenomena and their conditions of generationare discussed.
