Paper Abstract

A device is proposed which is based on the phenomenon of dependence of polarization state of a neodymium laser ((lambda) equals 1.06 micrometers ) passively Q-switched with a Cr4+:YAG crystal upon relative orientations of the switch and an intracavity partial polarizer. It is shown that such a device operates as an all-optical transistor. One of the main parameters (polarization) of the powerful neodymium laser can be controlled by the relatively weak signal delivered from a cw laser or laser diode, wavelength of which falls into the Cr4+:YAG crystal resonant absorption band (0.8 - 1.2 micrometers ).
