摘要 | Lasing at the edge of the reflection band or at a defect state within the reflection band of a thin one-dimensional feedback structure is used to create a large-area, thin-film laser source with transverse dimensions that can be much greater than the film thickness. Angular confinement of radiation propagating perpendicular to the layers leads to a spreading of the beam inside the medium which is much greater than the diffraction divergence. This enhances the spatial extent of correlation at the output surface of the thin film. When a pump source induces gain at the lasing threshold in a wide region, a spatially coherent monochromatic light beam is emitted perpendicular to the film surface from the entire gain region. Alternate embodiments of the present invention include a passive spatial filter and an active amplifier. |
其他摘要 | 在反射带的边缘处或在薄的一维反馈结构的反射带内的缺陷状态下,用于产生大面积的薄膜激光源,其横向尺寸可以比薄膜大得多厚度。垂直于层传播的辐射的角度限制导致光束在介质内的扩散,其远大于衍射发散。这增强了薄膜输出表面的相关空间范围。当泵浦源在宽区域中在激光阈值处引起增益时,从整个增益区域垂直于膜表面发射空间相干单色光束。本发明的替代实施例包括无源空间滤波器和有源放大器。 |
