The cascaded arc - a novel bright light source for sensitive broadband absorption spectroscopy

摘要

The development of a broadband photon source spanning the (V)UV range to the infrared is of general interest in many fields. Such a very bright and stable white light source is e.g. extremely useful to perform sensitive absorption spectroscopy. The total light absorption by a sample depends on the optical path length through the sample according to the law of Beer-Lambert.
