Single and multiple element 4-pass phase conjugate master oscillator power amplifier using diode lasers
Scaling laser diodes to high optical powers demands large emission apertures. Simple broad-area structures or laser diode arrays suffer from degradation of both the spectral and spatial mode as the emitting aperture increases in size. In addition, when multiple elements are combined, proper phasing is a difficult and sometimes impossible task.
