Abstract

Increase of the emission bandwidth of a high-pressure CO2 laser up to 1.5 cm−1 increases the multiphoton absorption cross-section of SF6. Comparison with the previously found [9] increased absorption for shorter pulses suggests that this is also a bandwidth effect. Spectral structures as narrow as 1 cm−1 above the 10th absorption step are invoked to explain the observations. The temperature effect, which disappears in the broad-band case, confirms this view.
