Abstract:
Calculating steady-state optical limiting characteristics of nonlinear Fabry–Perot resonators, we noticed that
the input-output characteristic shape does not depend on any resonator parameter. The intracavity medium
was assumed to have either third-order nonlinear refraction or absorption. In a double logarithmic diagram the
input-output characteristic can be divided into two regions, linear and nonlinear, which are both almost straight
lines with a relatively short curved section between them. The only dependent variable is the position of that
curved section (limiting threshold). Simple relations between resonator parameters, nonlinear coefficients and
the limiting threshold, enabling one to easily get nonlinear characteristics of such resonators whithout doing
nonlinear calculations, are presented.
