Abstract

The extraordinarily large thermal refractive index gradient of a nematic liquid crystal is employed for transverse self-phase modulation of a cw CO ₂ laser. The observed optical intensity limiting and switching are in good agreement with theoretical expectations and provide useful guidelines for infrared-beam-limiting applications.
