We are expecting that optical frequency comb are adopted in dilute-special-molecule’s gas-sensor systems. Before this work we had demonstrated narrower-than-two-MHz linewidth of each of the 10-GHz-spaced optical-frequency-comb components, the frequency control method of optical-frequency-comb frequency position. In this work, we propose a new method of dilute-special-molecule’s gas-sensor system using our original all-optical-gate output optical frequency comb. This comb have < 2 MHz linewidth components and sweeping comb’s spacing and frequency position, we are able to high resolution detects and divide absorption spectrum lines. In the result of the test acetylene as an object, because17 times of comb spacing was matched frequency space between objective two absorption lines (173.7 GHz), we successfully have detected two absorption line of acetylene. |
