紧凑型准混沌光腔

Compact Quasi-Chaotic Optical Cavity

Jonathan A. Fan, Evgenii E. Narimanov, Claire Gmachl

摘要:

提出了一种新型的三维凸多程光腔,它具有部分混沌光线动力学特性。光被定位在由腔支持的稳定的长路径长度轨迹附近,并且光束衍射被通常存在于部分混沌系统中的规则和混沌射线动力学区域之间的相空间屏障抑制。对于一个厘米大小的腔,该设计支持米级的光程长度,表明在痕量气体检测的未来应用。示例性腔体已经由中空的、镀金的丙烯酸外壳制成。我们的测量使用氦氖激光器和脉冲红色二极管激光器的腔光束图案和光程长度的表征,分别确认理论预测的光学动力学和腔的能力,以支持米级的路径长度。

英文摘要:

A novel, 3-dimensional, convex, multi-pass optical cavity with partially-chaotic ray dynamics is presented. The light is localized near stable, long-path length trajectories supported by the cavity, and beam diffraction is suppressed by the phase space barriers between the regions of regular and chaotic ray dynamics that are generally present in partially-chaotic systems. For a centimeter-size cavity, the design supports meter-scale optical path lengths, suggesting future applications in trace gas detection. An exemplary cavity has been fabricated from a hollow, gold-coated, acrylic shell. Our measurements using a HeNe laser and a pulsed red diode laser for characterization of the cavity beam pattern and optical path length, respectively, confirm the theoretically predicted optical dynamics and the ability of the cavity to support meter-scale path lengths.
