【 摘 要 】

New approaches to cavity enhanced absorption spectroscopy are presented. They are based on precise measurements of shape of cavity modes broadened and shifted in the vicinity of the absorber placed inside the high-finesse cavity. The usefulness of both techniques to accurate line-shape study is demonstrated on an example of a weak (3 → 0)13C16O transition.
