Abstract
The results of investigations into the suitability of condensed-phase parahydrogen as a Raman-shifting medium for infrared cavity ringdown laser absorption spectroscopy were reported. The conversion of ∼10-ns pulses of 532-nm radiation into first-, second-, and third-order vibrational Stokes radiation in bulk liquid and solid parahydrogen after a single 11-cm pass was observed. It was found that the liquid H2 yields more efficient conversion than solid H2 with certain focal geometries, and in case of the solid, a collimated or loosely focused pump geometry was more efficient than a tight focus.
