ABSTRACT:
A master oscillator power amplifier (MOPA) laser system includes a symmetrical master oscillator and an amplifier each having an optically pumped solid-state gain rod. An optical relay is located between the laser resonator and the amplifier gain rod. When the oscillator and amplifier gain media are equally optically pumped, the magnification and the distances from the optical relay to the resonator and the amplifier gain rod can be selected such that amplifier efficiency is maximized, independent of optical pump power, even if the diameters of the oscillator and amplifier gain rods are different.
