A Study on Structural and Optical Properties of Nanostructure MgxZn1-xO Thin Films Using Pulsed Laser Deposition
Published 2014-06-01“…For this paper, films have been grown under various deposition conditions in order to understand the effect of processing on the film properties and to specify the optimum condition, namely substrate at temperatures of 400°C, oxygen pressure (2×10-1) mbar, laser fluence 400 mJ, and with different Mg doping (x=0, 0.02, 0.04, 0.06), using double frequency Q-switching Nd:YAG laser beam (wavelength 532nm), repetition rate (1-6) Hz and the pulse duration of (10 ns), to deposit MgxZn1-xO films on glass substrates with thickness of about 200±10 nm for all MgxZn1-xO films at different deposition condition and the number of laser pulses was 100 pulses. The X-rays spectra revealed that the presence of diffraction peaks indicates that the polycrystalline of the films depended strongly on the Mg-content in the layers. …”

Accuracy of Ground Surface Interpolation from Airborne Laser Scanning (ALS) Data in Dense Forest Cover
Published 2020-04-01“…Using LiDAR data to collect ground surface data for forestry applications is a challenging scenario because the presence of forest vegetation will hinder the ability of laser pulses to reach the ground. The density of ground observations will be therefore reduced and not homogenous (as it is affected by the variations in canopy density). …”

Real-Time In-Process Evaluation of Spatter Area and Depth of Aluminium Surface in a Pulsed Laser Ablation Process Using Received Radio Frequency Power from Plasma Plumes
Published 2023-03-01“…In this paper, we describe a process for analysing the received radio frequency power (<i>RFP</i>) for an aluminium (Al) surface ablation process in atmosphere using picosecond laser pulses at a wavelength of 1064 nm. The analysis of the <i>RFP</i> was carried out on two sets of experiments, where two parameters of the laser (repetition rate of laser (<i>RRL</i>) and power of laser (<i>PL</i>)) were varied while other parameters remained constant. …”
