Saturable X-ray Absorption
Saturable absorption has been demonstrated for X-rays. In one study, a thin 50 nanometres (2.0×10−6 in) foil of aluminium was irradiated with soft X-ray laser radiation (wavelength 13.5 nanometres (5.3×10−7 in)). The short laser pulse knocked out core L-shell electrons without breaking the crystalline structure of the metal, making it transparent to soft X-rays of the same wavelength for about 40 femtoseconds.

Famous quotes containing the word absorption:
“The symbolic view of things is a consequence of long absorption in images. Is sign language the real language of Paradise?”
—Hugo Ball (1886–1927)
