title: Design and performance of a dual-laser instrument for multiple isotopologues of carbon dioxide and water.
abstract: A design and results for an instrument with a quantum cascade laser and an antimonide diode laser to measure simultaneously and with high precision seven isotopologues of carbon dioxide and water vapor. Methods and results for determining the effects that limit absorption noise at the level of 5x10(-6) are presented and discussed.
