摘要：

Nonlinear absorption and amplification of a probe laser beam can be controlled by adjustment of the intensity-modulation frequency and the wavelength of a pump laser beam. A demonstration of this effect in Er3+-doped fluoroindate glass is presented. The results show maximum amplification of the probe beam (similar to 12%) when a pump laser emitting 16 mW of power is modulated at similar to 30 Hz. In the limit of low modulation frequencies, or cw pumping, induced absorption of the probe beam is the dominant nonlinear process. (C) 1999 Optical Society of America [S0740-3224(99)02811-8].
