Abstract:Strong double-resonance signals are observed in silane pumped with a TEA-CO2 laser and probed with a tunable diode laser. The lineshapes of these signals have been modeled with an extension of three level density-matrix theory to the case of a large bandwidth pump laser. Up to 50% of the ground state population can be transferred to specific rotational levels of the dyad by CO2 laser pumping. Collision-mediated two-photon excitation to triad levels has also been observed.
