Stimulated emission in multiple-photon-pumped xenon and argon excimers.

A pumping process involving the multiphoton absorption of laser radiation at 3547 and 2660 A is employed in the investigation. Typically, about 25% of the incident pumping radiation is absorbed and effective in producing excimer fluorescence. The four cases studied include 2660-A-pumped argon, 2660-A-pumped xenon, 3547-A-pumped xenon, and 3547-A-pumped argon. Results concerning the on-axis and off-axis fluorescence obtained from the excimers are presented in a graph.

Third-harmonic generation in phase-matched Rb vapor.

The generation of 0.3547-micron radiation was performed by tripling 1.064-micron radiation in a phase-matched mixture of rubidium vapor and xenon. A third-harmonic nonlinear susceptibility in Rb vapor is confirmed. It is about 100,000 times greater than that of He. This large susceptibility is due to the large oscillator strengths and resonant enhancements resulting from Rb transitions in the near infrared, visible, and UV.
