Abstract
We report a novel optoacoustic detection scheme which is suited for use with low‐power radiation sources. The improved detection capability is demonstrated for SO2 with a frequency‐doubled dye laser of 1 mW uv output power, allowing the detection of SO2 concentrations as low as 0.12 ppb.Keywords
