Abstract

We investigate Nd:YAG master-oscillator power amplifier arrangements with an infrared-sensitive rhodium-doped BaTiO(3) photorefractive phase-conjugate mirror. In these setups the phase-conjugate mirror is simple to implement, compact, passive, and completely self-contained. We demonstrate a reasonable extraction efficiency (~50%), response times in the range of several minutes with our experimental conditions and an excellent ability of the phase-conjugate mirror to compensate for severe phase aberrations.
