Abstract
The extraordinarily large thermal refractive index gradient of a nematic liquid crystal is employed for transverse self‐phase modulation of a cw CO2 laser. The observed optical intensity limiting and switching are in good agreement with theoretical expectations and provide useful guidelines for infrared‐beam‐limiting applications.Keywords
