论文摘要
由于在微型微米尺度定制蒸气电池中，我们研究了由于在rubidium-Hydryogen混合物中的多普勒脱离三级系统中的相干效应而无反转的增益。细胞微型化导致原子与细胞壁的碰撞。与氢缓冲气体的高碰撞速率结合在一起，使我们能够观察到吸收光谱中的增益。此外，我们分析了细胞微型化在增益曲线进化中的作用。除了基本的兴趣外，在我们的微型细胞中观察增益而无需倒置的增益铺平了用于应用程序的方式，例如无反转的微型激光器。
We study gain without inversion due to coherence effects in a Doppler-broadened degenerate three-level system of a rubidium-hydrogen mixture in a miniaturized micron scale custom vapor cell. The cell miniaturization gives rise to collisions of atoms with the walls of the cell. This, combined with the high collision rate with the hydrogen buffer gas allows us to observe gain in the absorption spectra. Furthermore, we analyze the role of cell miniaturization in the evolution of the gain profile. In addition to fundamental interest, the observation of gain without inversion in our miniaturized cells paves the way for applications such as miniaturized lasers without inversion.
