Military uses of nonlinear optical materials range from laser beamsteering and control of beam quality to eye-protection and guided-wave photonic devices and components. Materials for optical phase conjugating are important for correcting laser beam aberrations to near diffraction-limited beam quality, for combining a laser array into a single coherent beam and for imaging through atmospheric turbulence. Materials for eye-safe optical sources and electro-optic sensor and eye protection are also important for battlefield applications. Materials for other military applications include guided-wave modulators and switches for photonics, optical correlators for automatic target recognition, 2-D spatial light modulators for high-speed parallel processors and metrology of surface motion and strain or air turbulence near an aerofoil surface. Nonlinear optical NLO techniques are also finding new applications in the generation and control of microwaves and millimeter waves.
