Publisher:Ohio State University
A novel two-photon absorption (TPA) laser system in cw single-mode operation vas built to demonstrate the feasibility of observing two-photon excitation spectra of gaseous molecules. A commercial cw dye laser was modified to perform the intracavity TPA work. The two-photon excitation spectrum of naphthalene (0.07 Torr) with superb signal-to-noise ratios is presented to illustrate the applicability of this new technique.
