“…But a system for BEFWM becomes complicated because of the phase mismatch among the four waves. A reflectivity greater than 10 4 was reached for gain saturation [8], but a decrease in reflectivity due to the intense pump beam occurs [9][10].…”

We investigate the tracking ability of an optical phase conjugator using a commercial CCD array and a projector LCD panel. This system allows one to use two separate laser oscillators for capturing interference patterns and generating phase conjugate light. Since a long coherence length is not required for the latter part, amplification of the phase conjugate light can be easily attained by using a laser oscillator for high-power applications such as machining. The wavelengths of the two laser oscillators can be independently chosen. For our experimental configuration an amplification factor of 7.8×10(4) is theoretically possible. Also, a formula for the maximum tracking range is derived. The proposed system is particularly suitable for power transmission by light.

“…Holographic lasers, four-wave mixing, and phase conjugation in laser crystals and holographic oscillators have been demonstrated in YAG, vanadate, and Ti:sapphire crystals that use gain gratings as holographic elements. [17][18][19][20][21][22] Semiconductors can also have optical gain when they are optically or electrically pumped. Typical laser gain in GaAs is near g ϭ 300 cm Ϫ1 .…”

Dynamic holography in a broad-area optically pumped vertical GaAs microcavity

A broad-surface-area vertical GaAs microcavity was operated as an adaptive holographic film. The cavity mirrors were transparent to high-energy (millijoules per square centimeter) hologram writing pulses at a wavelength of 730 nm that generated optically pumped gain gratings in a 1-m-thick active layer of GaAs. The gain gratings were probed with a low-intensity (mW) tunable laser at wavelengths near the GaAs band edge in the high-reflectance bandwidth of the cavity Bragg mirrors. When the structure was designed with low mirror reflectances ͓(R 1 R 2) 1/2 ϭ 90%͔ to operate below the lasing threshold, the cavity resonance bandwidth was sufficiently broad to permit homogeneous hologram readout over a large (several square millimeters) area. Diffraction efficiencies of approximately 10% were predicted and approached experimentally. These results represent a first step toward the realization of a holographic vertical-cavity surface-emitting laser structure.
