Figure 3.

Absorption coefficient (colored lines) as a function of photon energy. Solid lines are for α1(ω). Dashed lines are for α3(ω,I), and dotted lines are for α(ω,I) = α1(ω) + α3(ω,I). The results are for R1 = 10 nm, R2 = 20 nm, L = 20 nm, F = 0, and I = 2×104W/cm2. Several values of the hydrostatic pressure have been considered.
