    Notes: Abstract. A pentagon-shaped undoped BaTiO3 crystal was used to construct a high-quality mutually pumped phase conjugator. It yields two very stable phase-conjugate outputs (±1.7% fluctuation in intensity) with high reflectivity (the highest ≈45%) when the two incident beams are of equal intensities. The response time of the conjugator is rather fast (≈3 s) and the tolerance of the acceptance angle is large too (≈100°). Fine structures (35 μm) in an image, after passing through a phase aberrator, can be recovered by the conjugate waves yielded by this conjugator.

    Nonlinear capillary-gravity waves under an edge condition (2000)

    Notes: Abstract The objective of this paper is to investigate the forced motion of nonlinear capillary-gravity waves in a waterfilled circular basin by a harmonic vibration applied to its side wall under Evans's or Hocking's edge condition at a contact line. The forcing frequency is near a resonance frequency under the classical edge condition of the basin. Two complex-amplitude equations for the excited eigenmode at the resonance frequency corresponding to these two edge conditions are derived. The solutions to these equations display quite different behavior and an edge condition indeed has a great influence on the excited surface waves.
