Er:YGG is a promising candidate for greenhouse-gas LIDAR due to fortuitous transitions around key absorption lines of carbon-dioxide and methane. We present growth of crystal films by pulsed-laser-deposition, their spectroscopy and initial characterization as amplifiers. OCIS codes: (310.0310) Thin films; (220.4610) Optical fabrication; (230.7390) Waveguides, planar; (130.0130) Laser materials;...

In this research similar joining of NiTi shape memory alloy was studied. For this purpose, NiTi alloy in the form of wires with circular cross section possessing martensitic phase structure at room temperature was used. By utilizing Nd:YAG pulsed laser welding method followed by optimizing its technical parameters, a defectless joint in terms of appearance and metallurgical properties was obtai...

Polydimethylsiloxane (PDMS) is a silicone-elastomer that owes its large application in the field of stretchable electronics to chemical and thermal stability, transparency, flexibility, non-toxicity, compatibility, low cost. PDMS versatile material because it can be used both as an elastic substrate and, after functionalization, active for design electronics. One possible route functionalizatio...

Thin films of ZnO have been deposited on glass and silicon substrates by the pulsed laser deposition technique employing a KrF laser ~l5248 nm!. The influence of the deposition parameters, such as substrate temperature, oxygen pressure, and laser fluence on the properties of the grown films, has been studied. All the films grown over a rather wide range of deposition conditions were found to be...

Thin films of poly (lactide-co-glycolide) (PLGA), a biodegradable polymer, were deposited on Si wafers by both conventional pulsed laser deposition (PLD) and matrix assisted pulsed laser evaporation (MAPLE) using chloroform (CHCl3) as a matrix solvent. This research represents an initial study to investigate the deposition characteristics of each technique at comparable conditions to gain insig...

Pulsed laser deposition (PLD) has been proposed several years ago as a suitable technique to deposit a pure Mg film over a radio frequency (rf ) gun Cu backflange in order to obtain a high efficiency photocathode surface for the generation of high brightness electron beams. In this paper we report preliminary experimental results on the emission properties of a PLD grown Mg film within the high...
