Abstract

Liquid phase epitaxy (LPE) is a suitable technique to produce diode laser-pumped solid state lasers with a planar waveguide structure. The thin films of Nd³⁺, Ga³⁺ and Lu³⁺ doped YAG have been grown form a supercooled molten garnet-flux high temperature solution on undoped YAG substrates by the standard LPE dipping technique. The emission spectra and fluorescence lifetimes have been measured for Nd:YAG layers with different concentration of Nd³⁺ ions. Additionally, the films were investigated versus concentration of neodymium, gallium and lutetium using ESR, x-ray diffraction and micro interferometric techniques. According to above measurements it can be concluded that the obtained epitaxial structures are of good quality.
