Line Plot from Scientific Research

Self-induced intensity change as a function of CW optical signal, due to optically induced deformation of liquid film of initial thickness of ~1 μm. The increment steps were of ±1 mW and with relaxation time between successive power levels ~3 s to allow sufficient relaxation into stable configuration. The dashed lines ( P n l ) represent nonlinear output response obtained by subtraction of the corresponding input power ( P l ) defined by Eq. ( 1 ).
