Cascaded Optical Kerr Gate for Fluorescence Measurement With High Signal-to-Noise Ratio

Zhenqiang Huang;Zhen Kang;Wenjiang Tan;Jinhai Si;Xun Hou

IEEE Photonics Technology Letters
Year: 2024 | Volume: 36, Issue: 1 | Journal Article |
Traditional optical Kerr gates (OKG) often suffer from leakage fluorescence background when sampling and measuring fluorescence spectra due to the limited extinction of the polarizers used in optical Kerr gates. In this letter, we propose a cascaded optical Kerr gate (COKG) for measuring fluorescence spectroscopy with a high signal-to-noise ratio by suppressing this leakage fluorescence background...Show More
