Abstract

A resonance Raman detection system (RRDS) is proposed in this paper. The system is composed of a miniature ultraviolet frequency sweep laser (UFSL) and a controller and data analyzer (CDA). The UFSL consists of a pulse semiconductor laser (PSL) module, a fiber laser module (FLM), and an ultraviolet frequency sweep module (UFSM). Among the molecules of the tested object, those molecules, whose resonance Raman excitation wavelength equals the ultraviolet sweep wavelength and Stoke Raman spectral intensity will then increase to 104 to 106 times due to the resonance Raman effect, can be detected in the case of extremely tiny content. The advantages of the RRDS include integral structure of electronics and optical fibers, miniature of UFSL, fast regulation of the ultraviolet laser wavelengths, elimination of fluorescence interference.
