Abstract

The present invention provides an optical detection system comprising an illumination unit and a detection unit. The illumination unit comprises two laser beams of two different wavelengths. One beam is used to excite targeted molecules in a sample to their excited states. The other beam is used to induce the excited molecules in the sample to generate a stimulated emission signal. The stimulated emission signal can be used for long-distance detection due to its coherent property. Its extraction from the detection unit can be realized by demodulating the second beam's intensity change.
