Abstract

Trace of CO₂ gas of 1% was detected utilizing absorption spectroscopy with an incoherent broad band light source. The light source was the amplified spontaneous emission of the ⁵I₇→⁵I₈ transition from a Tm⁺³/Ho⁺³ co-doped silica fiber pumped near 800nm. Vibrational bands of CO₂ in the range of 1.9-2.1 μm was detected in an absorption cell of 1.1 m path length.
