Techniques are described for phase locking two or more lasers using phase-conjugating mirrors. Any changes in the optical cavity length or in the spatial mode structure of the optical beams are automatically compensated. Two argon-ion lasers were locked using a photorefractive crystal of BaTiO3 acting as a self-pumped phase-conjugating mirror.

    Abstract. We demonstrate phase conjugation and dynamic holography by degenerate four-wave mixing in a continuous-wave diode-pumped Nd:YVO[sub 4] laser tot the first time. A phase-conjugate reflectivity of 1.4% is obtained with a 12 W diode power. The experimental results and the optimizing...

    Continuous wave (cw) phase conjugation of a HF laser beam has been observed using resonant degenerate four-wave mixing in a HF gas absorption cell. A HF laser was operated in the P1(8) transition to provide total (forward plus backward) pump beam and probe beam intensities of about 400 and 30...

    A method is described for transmission of images through a distorter. The technique uses the principle of phase conjugation and employs two holograms. The conjugate of one of the reference beams acts as a carrier for the signal through the distorting medium.

    An experimental investigation is made of the influence of strong self-interaction of the reference waves on phase conjugation in four-wave mixing of cw radiation in a medium with a thermal nonlinearity. It is shown that the thermal lens formed by the Gaussian reference beams reduces the...

    The graded index (GRIN-like) medium generated by gas inside a heated steel pipe when rotated about its longitudinal axis has the ability to focus a laser beam. While the effective focal length of such a system has previously been studied, there is little information on optical phase aberrations...
