描述了一种用于检测亚稳态的光-光双共振（OODR）激光诱导荧光（LIF）。OODR采用双激光激发A-B和B-C氮跃迁。本文提出了一种灵敏的高压放电检测方法。我们通过激发/探测方案测试了其相对于传统单光子LIF的灵敏度，其中所需的两个波长由临时单激光装置产生。其他单激光配置，可能允许灵敏度接近两个数量级比传统LIF提出。这种增益对于非平衡高压放电的检测特别有用。
An optical–optical double resonance (OODR) laser induced fluorescence (LIF) for the detection of the metastable is described. OODR employs the double laser excitation of A–B and B–C nitrogen transitions. Here it is proposed as a sensitive approach to detect in high-pressure discharges. We have tested its sensitivity with respect to conventional single photon LIF by an excitation/detection scheme in which the two wavelengths required are generated by a provisional single laser setup. Other single laser configurations that might allow a sensitivity close to two orders of magnitude larger than that of conventional LIF are proposed. Such gain can be particularly useful for the detection of in non-equilibrium, high-pressure discharges.
