Abstract

By two-photon pumping covering a wide wavelength region of 720-740 nm in potassium vapor, yellow stimulated diffuse-band radiation corresponding to the transition 23∏g → a3∑u+ of molecular potassium is generated. The excitation mechanism is discussed in detail.

Blue (455.0-465.0 nm) and violet (407.0-418.0 nm) diffuse-bands of stimulated radiation are generated via two-photon excitation of lithium dimer by pumping laser tuned to any wavelength in the region of 620.0-660.0 nm and via two-photon resonant excitation of atomic Li, respectively. The mechanisms involved are discussed.

UV and violet stimulated diffuse band radiation by two-photon pumping in Na2

Zugeng Wang, Kai-Chang Zhang, Xiao-Ling Tang +1 more

This paper reports the UV and violet diffuse band radiation generated by two-photon pumping in Na2 by focusing the pumping beam (~ 10 mJ) from a pulsed dye laser into a heat-pipe oven containing sodium. Measurable forward stimulated diffuse band radiation existed at 350.0-385.0 nm and 405.0-460.0 nm over the whole pumping region from 620.0 to 670.0 nm. The radiation corresponded to transitions from different high-lying triplet g states to the lowest triplet state. The signal intensity related to the pumping wavelength. The stronger signals were there where two-photon pumping was enhanced by singlet-triplet mixing levels. The weaker signals were assumed to relate to the collisions either transferring energy from the A ′ Σ u + to the b3Π g state after the first photon excitation and then pumped by the second photon excitation from the b3Π g state to a high-lying state, or were due to collisional transfer from a high-lying singlet to a nearby triplet state.
