Web28 jul. 2024 · To obtain interesting concentrations for final applications, it is necessary to exploit high-energy lasers, which are quite expensive. In this review, we discuss the pros and cons of the use of laser ablation synthesis for the production of Ag antimicrobial colloids, taking into account applications in the food packaging field. WebDisadvantages of Diode Lasers Diode laser beams are highly divergent, meaning “wedge-shaped,” instead of straight and parallel, and have shorter coherent distances, which makes for inferior quality in optics performance. They are not as well-suited as helium-neon lasers for high-quality holography. The gain medium of the laser, as suggested by its name, is a mixture of helium and neon gases, in approximately a 10:1 ratio, contained at low pressure in a glass envelope. The gas mixture is mostly helium, so that helium atoms can be excited. The excited helium atoms collide with neon atoms, exciting some of them to the state that radiates 632.8 nm. Without helium, the neon atoms wou… lg arrowhead\u0027s
