Abstract

A novel type of photo-acoustic Raman spectroscopy with no tuning device is used for trace gas detection in the atmosphere. The scheme can be applied to many other Raman-active gases and is suitable for long-term monitoring of the atmosphere. The system is simple and reliable. Sensitive detection of inflammable gas such as H2 and CH4 is also useful as a gas-leak monitoring system in the chemical plants and gas pipe lines.
