Spurious sidebands observed in the noise spectrum of colliding-pulse mode-locking dye lasers result from coupling of the longitudinal mode beating modulations of the (argon-ion) pump laser with the dye laser. We achieve a 50-dB amplitude noise reduction at the mixing frequencies by inserting a single-frequency étalon in the argon-laser cavity. Furthermore, we find the amplitude noise of the col...

Introduction The aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (APPJ) and interactions of this technology with double-stranded DNA using the polymerase chain reaction (PCR) and single-strand conformation polymorphism (SSCP) techniques. Materials and Methods The plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...

This paper presents results that show the effect of hydrothermal carbonization and subsequent cold plasma jet treatment with helium argon on structure sorption properties a material—spent brewery grain. Treatment activated carbon, atmospheric jet, was used comparatively. The activation pore materials carried out by volumetric method at low pressure (N2, 77 K). specific surface area as well tota...

It is about the construction of a sputtering system, through use cold plasma reactor, for deposition metallic thin films. Basically, this system works by ejecting atoms material (target) bombardment argon ions. This process takes place ionization gas, which has its ions accelerated towards target and when they collide with material, ejection occurs, these separate are deposited on substrate, fo...
