摘要：

A femtosecond KrF excimer laser is focused into molecular hydrogen to generate a multifrequency laser beam, consisting of many vibrational and rotational lines, in a transient Raman regime. The intensity distribution is unchanged from 5 to 13 atm, in contrast to the case of nanosecond laser pump. The efficiency for generation of the rotational lines is improved by increasing the peak power, especially at longer wavelengths, indicating power-dependent and wavelength-dependent behavior of this Effect, as expected from theory.
