| Abstract: | The results of a study of nonlinear refraction and nonlinear absorption at a wavelength of 532 nm in an LGO (Li2Ge2O15) crystal by Z-scan methods are presented. It is shown that the nonlinear refraction is caused by self-focusing of the laser radiation, whereas the nonlinear absorption is three-photon in nature. The possibility of using an LGO crystal for producing the optical limiting of laser radiation of picosecond duration is demonstrated. |
