    Abstract

    This paper describes laser spectroscopy using a photonic bandgap fiber as a gas cell. The photonic bandgap fiber has an air hole core about 10μm in diameter at its center. After passing the test gas and a laser beam through the core simultaneously, the absorption spectrum is measured by laser spectrometry. The new method has the following features compared with the conventional gas cell method or the white cell method: 1. Extremely small amounts of gas can be measured. 2. Stable and highly-sensitive measurement that is less subject to environmental fluctuation is possible. This paper confirms the effectiveness of the new method by measuring the absorption spectrum of ammonia gas.
