Long Optical Path Lengths by A Compact and Robust Chaotic Optical Multi-Pass Cavity

Princeton Docket # 08-2414 Typical optical gas sensors utilize multipass cells to probe molecular species by absorption spectroscopy. Existing multipass cells are usually costly, large, and lack robustness, which limits their use for portable systems. Princeton researchers have designed and fabricated a highly compact and robust optical cavi...
