Nanocomposite thin films consisting of nanometer-sized Ag particles embedded in amorphous Ba0.5Sr0.5TiO3 matrix were prepared on fused silica substrates by an alternating pulsed laser deposition method. Their optical nonlinearities have been studied using the Z-scan method. The surface plasmon resonance (SPR) peak shifts to red and increases with the increasing the volume fraction of Ag in the nanocomposite films. The magnitude of the third-order nonlinear susceptibility of the nanocomposite with an Ag volume fraction of 3.3% was calculated to be ∼2 × 10−8 esu at the SPR wavelength.

Perovskite KTa0.65Nb0.35O3 (KTN) thin films were grown by pulsed laser deposition (PLD) on single crystal SrTiO3 (100) substrates. X-ray diffraction (XRD) analyses illustrate epitaxially grown of KTN thin films along the (100) orientation. The surface morphology of films observed by atomic force microscope (AFM) showed that, the surface of films was smooth and uniform built from regular, ordered and dense grains with the root mean square (RMS) roughness of 5.602 nm. Linear and third-order nonlinear optical properties of the films were investigated by using transmission spectra as well as the Z-scan technique with femtosecond laser pulses, respectively. The open-aperture and closed-aperture Z-scan curves of KTN thin films were obtained in the first measurement. The calculated nonlinear refractive index was , the nonlinear absorption coefficient is = , and the real part and imaginary part of the third order nonlinear susceptibility are and respectively.

AbstractUltra-fast pulsed laser deposition using high-repetition-rate short-pulse lasers has been shown to provide high optical quality, super smooth thin films free of scattering centres. The optimized process conditions require short ps or sub-ps pulses with repetition rate in the range 1-100 MHz, depending on the target material. Ultra-fast pulsed laser deposition was used to successfully deposit atomically-smooth, 5micron thick As2S3 films. The as-deposited films were photosensitive at wavelengths close to the band edge (≈520 nm) and waveguides could be directly patterned into them by photo-darkening using an Argon ion or frequency doubled Nd:YAG laser. The linear and nonlinear optical properties of the films were measured as well as the photosensitivity of the material. The optical losses in photo-darkened waveguides were <0.2 dB/cm at wavelengths beyond 1200nm and <0.1 dB/cm in as-deposited films. The third order nonlinearity, n2,As2S3, was measured using both four-wave mixing and the z-scan technique and varied with wavelength from 100 to 200 times fused silica (n2,Silica ≈3×10-16 cm2/W) between 1500nm and 1100nm with low nonlinear absorption.Encouraged by the Ultrafast laser deposition results, we have built a new specialized modelocked picosecond laser system for deposition of optical films and for laser formation of nanoclusters. The newly developed “state of the art” powerful Nd:YVO laser can operate over a wide range of wavelengths, intensities, and repetition rates in MHz range. A brief description of the 50W laser installation is presented.
