Abstract: Optoacoustic and luminescence methods were used to investigate nonlinear absorption and multiphoton dissociation of monosilane in single- and two-frequency laser fields by tuning in the region of the emission lines of ¹²C¹⁶O₂ and ¹³C¹⁶O₂ lasers. For several lines in the 11-μm lasing region, discovered by single-frequency excitation, the efficiency of these absorption and dissociation processes was a factor of 3–10 higher than that in the traditional 10-μm region. The multiphoton dissociation efficiency of SiH₄ was increased further by two-frequency excitation.
