Abstract:

In most substances which exhibit the stimulated raman effect under high intensity laser excitation, the presence of self-focusing makes quantitative measurements almost impossible. It is shown that in hydrogen gas, which has a very high self-focusing threshold, the stimulated raman effect in an amplifier behaves according to the simple parametric theory. The frequency sharpening in the stimulated emission is used to make a quantitative study of the line shift of the Q1 vibrational line of H2 as a function of pressure, temperature and foreign gas admixture. Some of these results are then used to measure the line width of the Q1 line in a raman amplifier. Results are presented of these experiments and other cases are discussed in which the stimulated raman effect can be used to yield information about the scatterer. Author
