THE NON-CONTACT PROCESS ELIMINATES THE RISK OF SHARP BLADES DAMAGING THE FIBER AND DOESN’T REQUIRE THE USE OF HAZARDOUS CHEMICALS.
I simply have HW. I got the essay from my friend. The only thing i need from you to revise the essay change the words and keep the same ideas and main concepts. I only need to make it look better with different words.
make it more professional as much as you can
it is only one page esaay !
Revise it and edit it.
Laser Materials Processing and Industrial Applications
At 7 P.M on Thursday, I went to the csun campus to attend the lecture which was presented from proffers Xie. It was full of benefits and lots of great new information. First topic that attracted me and make more focus on the lecture when he hit the slide that showed laser surface ablation and laser stripping. Also, I liked one more thing that was about laser surface treatment. From what I learned form that lecture I will briefly talk about these general information. There are several key parameters to consider for laser ablation. The first is selection of a wavelength with a minimum absorption depth. This will help ensure a high energy deposition in a small volume for rapid and complete ablation. The second parameter is a short pulse duration to maximize peak power and to minimize thermal conduction to the surrounding work material. This is analogous to a vibrating system where the mass is large and the forcing function is of high frequency. This combination will reduce the amplitude of the response. The third parameter is the pulse repetition rate. I will briefly explain what I understood from laser stripping. Laser stripping is the fast accurate way to remove acrylate and polyimide coatings from optical fiber. The laser process can be applied to fiber ends and can create windows of virtually any length and at any point along the fiber. The non-contact process eliminates the risk of sharp blades damaging the fiber and doesn’t require the use of hazardous chemicals. The stripped fiber is clean, residue free. Finally, I will talk about laser surface treatment. Laser surface treatment is claimed that laser surface treatment has the greatest growth potential in the field of laser materials processing. Laser surface treatments offer a wide range of possibilities to achieve desired surface properties. This is used to reduce wear and improve fatigue resistance of machine components especially where hard surface layers are required on tough and possibly cheap base materials and where no measurable thermal distortion is allowed.
