Measurement of the nonlinear refractive index of air constituents at mid-infrared wavelengths
, 2015 We measure the nonlinear refractive index coefficients in N$_2$, O$_2$ and Ar from visible through mid-infrared wavelengths (\lambda = 0.4 - 2.4 {\mu}m). The wavelengths investigated correspond to transparency windows in the atmosphere. Good agreement is

A Power Efficient Audio Amplifier Combining Switching and Linear Techniques [PDF]
, 1998 Integrated Class D audio amplifiers are very power efficient, but require an external filter which prevents further integration. Also due to this filter, large feedback factors are hard to realise, so that the load influences the distortion- and transfer
