Paper Abstract

Dependence of the negative nonlinear absorption effect (NNA effect) on modulation frequency was investigated in an erbium-doped lutetium aluminum garnet (Er:LuAG) crystal at the wavelength of 787.8 nm. When the intensity of the incident laser irradiated on Er:LuAG and Er:YAG crystals was wavy, those crystals were observed NNA effect that the transmitted laser intensity shows opposite phase of the incident laser at the wavelength of about 788 nm. The transmitted waveforms changed to the opposite phase of the incident waveform for modulation frequencies up to 1 GHz. For 1 GHz, the peak of the reversed-phase waveform was shifted by approximately 250 ps.
