| Popis: | Laser Assisted Molecular Beam Deposition (LAMBD) is a pulsed laser ablation technique which utilizes a train of gas pulses to precisely control the chemistry and transport of species to be deposited on a substrate. The LAMBD technique has been used to grow films on a variety of substrates and to ablate a variety of target materials including: metals, metal oxides, metal halides, Si, C and SiC. In addition, a variety of more complex composite films such as Cu embedded polymers, Yba2Cu3O7-x and organic doped TiO2 and Al2O3 have also been produced. These films have been analyzed by Raman scattering, SEM, EDX, FTIR, ESCA, NMR, mass spectrometry surface profile measurements to determine film structure and composition. Recently a successful program has been undertaken to show the potential of LAMBD to generate photonic films. Work done on up-conversion of IR light into the visible using LAMBD generated composite TiO2:APSS films will be described. These results demonstrate the potential of using LAMBD sources as a means of depositing a variety of high quality photonic films.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
