Nonlinear Infrared Generation in Alkali Metal Vapors:Steady State Susceptibilities and Dynamic Behavior. Effective Relaxation Rates and Preliminary Raman Gain Predictions for the Cs System. Technical Progress Report July 1, 1986-December 31, 1986.

摘要

Effective relaxation rates for atomic cesium pumped by doubled Alexandrite radiation are presented. Laser radiation levels are 8S 1/2 and 9S 1/2; resonance levels 3 = 8P 1/2 and 8P 1/2, respectively. In addition, Raman gain is represented in two graphs which plot chi per atom (10 to the -13 power) at Raman peak versus the infrared wave number per centimeter and the corresponding doubled Alexandrite wave number. One graph covers resonance level 8P, the other 9P; in both cases cesium is pumped with a peak pulse height of 0.5 MW in a 200 micrometer diameter spot size.
