Abstract

We present experimental intracavity absorption measurements carried out in a commercial Ar+-ion laser with a modified resonator. The samples were aqueous solutions of Rhodamine 6G. The smallest detectable concentration was 1 × 10−13 mol/L for λ = 488 nm. This is equivalent to an internal absorbance of 3.5 × 10−9. Similar measurements were performed with λ = 514.5 nm, but time- and space-periodic intensity fluctuations, particularly at lower light levels, reduced the sensitivity of the absorption detection.
