Nonlinear refractive index and "DC" kerr constant of liquid CS2at 10.6 µm

The "dc" Kerr constant of CS
2
has been measured at 10.6 μm and found to be
(2.9 \pm 0.8) \times 10^{-8}
statvolt
^-2
cm. This yields a value of
(2.1 \pm 0.7) \times 10^{-11}
statvolt
^-2
cm
²
for the nonlinear refractive index.
