Abstract
A phase conjugate mirror is formed of a compound semiconductor doped with DX centers, such as silicon doped gallium-arsenide, through which are passed three light waves of the same wavelength but in different directions for non-linear four wave mixing. The phase conjugate mirror is used as one mirror of a confocal resonator housing a laser medium to form a laser and light from such laser is used to form the three waves of the same wavelength used to pump the phase conjugate mirror.
