Abstract

The applicability of a pyroelectric detector (PED) to multiphoton absorption measurements (MPA) under ir laser excitation of molecules was examined. The possibility of MPA measurement of SF₆ molecules in the pressure range of 10^-3÷10^-1 Torr with a time resolution of ∼ 7 μs has been shown. It has been demonstrated that the degree of vibrational relaxation of highly vibrationally excited molecules at PED surface does not depend on excitation level under the studied conditions.
