Abstract：
 Present invention discloses photons crystal optical fiber probe transducer based on nano particle surface enhancing Raman spectra belonging to laser Raman spectra detection technique. Combining photons crystal optical fiber PCF and SERS spectral technique to obtain PCF-SERS probe transducer having SERS activity, PCF-SERS probe covered with cycle arranged airport, the inner wall of central light guiding air core on PCF-SERS probe end having SERS activity nano metal granule. Said invention can be used in gas and liquid molecule detection with low background noise and high sensitivity, and making exciting light and SERS signal light existing steady mode field in PCF to realize very transmission loss, thereby suitable for on line analysis, real-time analysis, living body analysis, and in situ detecting etc.
