  Laser Molecular Beam Epitaxy (Laser-MBE)[1] inherits from Pulsed Laser Deposition (PLD) and conventional Molecular Beam Epitaxy (MBE).
    Laser-MBE is designed especially for high melting point oxide with complex chemical structure and multi-elements.

Reflectance High Energy Electron Diffraction (RHEED) and other in-situ techniques are adapted for real-time control and growth mechanism study. Good RHEED intensity oscillations and almost perfect HRTEM pictures are obtained. 
    We adapt optical oblique-incidence reflectivity difference
(OIRD)technique [2] to the epitaxy chambe, which provide a new method to study the oxidation reaction[3] on the substrate surfaces.
