The other main application of fiber lasers is for telecommunication.. While very efficient on metals, fiber lasers have low effect on most plastics and organic materials due to their lack of absorption at the current wavelengths light is emitted.. Excimer/UV Lasers.. Excimer lasers are pulsed gas lasers that use a mixture of gas to generate laser ..

Types of Lasers There are many types of lasers available for research, medical, industrial, and commercial uses.. Lasers are often described by the kind of lasing medium they use - solid state, gas, excimer, dye, or semiconductor.. Solid state lasers have lasing material distributed in a solid matrix, e..g.., the ruby or neodymium-YAG (yttrium aluminum garnet) lasers.. The neodymium-YAG laser emits ..

Method #1: Direct generation of ultraviolet laser (Excimer lasers) Noble gases typically don’t interact with other elements.. However, if they are excited (by an electrical discharge for instance), they can bind to other atoms to form a very short-lived molecule called an excimer.. Excimers emit photons of UV wavelength to release excess energy ..
The fiber laser engraver utilizes a similar power source as the fiber laser cutting machine, requiring less power.. While a fiber cutting machine requires a minimum of 300W, a fiber marking machine requires a maximum of 120 to 150W.. For Example, the fiber laser cutting machines have power supplies ranging from 300W to 8000W..

Traditional excimer lasers have pulse lengths in the range of 10 to 20 ns.. In a study on the effect of the pulse length on the efficiency and quality of drilling, Schoonderbeek2 used a XeCl laser to drill 125µm-thick aluminum and found that long pulses (104 ns) with high peak power (15 kW) gave the best hole quality (see Figure 1)..

In fiber lasers, the gain medium is an optical fiber (silica glass) mixed with a rare-earth element.. The light guiding properties of the optical fiber are what makes this type of laser so different: the laser beam is straighter and smaller than with other types of lasers, making it more precise.. Fiber lasers are also renowned for their small ..

UV Lasers.. UV lasers work a little differently to their CO2 or Fibre based siblings as they do not damage the materials surrounding surface, using a far lower power form of marking.. This makes them the best of the bunch when it comes to “marking”, suitable for anything from fruit, to glass, teflon, diamond, silicone, plastic and precious ..
Fiber Bragg gratings are produced by exposing a step-indexed, germanosilica fiber to intense ultraviolet (UV) light, typically from a krypton fluoride (KrF) excimer laser (at 248 nm) or frequency-doubled argon-ion laser (at 244 nm).. Absorption of this light in the germanium-doped core causes a permanent change in the refractive index of the ..
