Abstract :
Since 1995, MEECO Inc., in collaboration with Princeton University, has been developing cavity ring-down spectroscopy (CRDS) for trace gas measurement. This work provided the first demonstration that CRDS could be used with highly attractive continuous wave (CW) semiconductor diode lasers. CW single-mode semiconductor diode lasers make CRDS commercially viable, thanks to their small size, low power requirements, long lifetime, monolithic construction, and modest cost.
