Laser technology caters to all the industry needs & demands of different types of consumers and in a great way. Today, it is a new buzzword all around the world. Its flexibility, reliability, cost-effectiveness, and innovative laser cutting techniques, such as marking and engraving, have made many things simpler. Today, we will read about laser technology in detail, its features, applications, advantages, how it is used, and beyond.
How is Laser Technology Being Utilized?
Today, lasers are the key elements of many of the products or commodities that we use in our day-to-day life. Some consumer products, such as DVD players or BluRay, depend on laser technology in order to read information from the disks. Plus, the barcode scanners depend on lasers for the processing of information. Laser technology is also utilized in various surgical processes, for example — LASIK eye surgery. In manufacturing industries, lasers are utilized for marking, engraving, cutting, and drilling a wide range of substances.
There are so many applications for laser technology, some of them are mentioned below:
→ Laser Surgery
→ Bar Code Readers
→ Laser Spectroscopy
→ Laser Range Finding
→ Holographic Imaging
→ Information Processing, i.e., DVDs and BluRay
→ Laser Material Processing such as Cutting, Engraving, Marking, Drilling, Surface Modification, etc.
We have discussed the applications of lasers in detail in the upcoming paragraphs.
Advantages Of Using Laser Technology
Technology and time together have propelled us into a world where laser etching, marking, and engraving procedures are coming to be better when it comes to the cost and quality metrics of so many industries. High in accuracy and precision, laser markings and engravings are being accomplished on different types of surfaces which include alloys, copper, gold, silver, brass, carbide, platinum, titanium, stainless steel, plastics, aluminium, and medical-grade alloys as well.
Here are a few benefits of laser technology that you must become familiar with:
➩ The laser engravings and markings do not fade away with time or become less discernible with time.
➩ Laser markings are known for their high-temperature assistance, reliability, durability, and micro-coded markings that don't use toxic solvents, acids, or inks on every bio-compatible base.
➩ The laser marking solutions are tamper-proof or contact-free, and they can surpass abrading, corrosion, and handcuffing in order to help the cause product tracking, forgery prevention, and beyond.
➩ With a wide range of applications, it helps in enhancing the aesthetics and monetary value of various products by making them look more attractive for higher market penetration.
Applications Of Laser Technology Explained In Detailed
➥ Food Industry
In the food industry, lasers are utilized to make markings related to brands, codes, and all types of information related to nutrition on food packages. It offers easy yet steady performance, continuous working ability, and fine lines. The laser applications are proving to be non-toxic, pollution-free, odourless, and have low processing cost techniques for extensive usage.
➥ Nuclear Energy
Nuclear power plants can be defined as a type of steam thermal power plant where they can produce heat steam inside the reactor furnace. The presence of an atomic furnace there requires an atomic radiation field and insulating wall. Laser technology helps the workers perform duties effectively and protect themselves in the power plant. Also, one of the most economical ways to enrich general uranium is laser isotope separation. Lasers also play a vital role in the search for a better way to track down the power of fusion.
➥ Garment Industry
The laser cutting technology helps garment manufacturers achieve standard-sized, minor deviation clothing substances with low prices and high-efficiency intakes in place. Graphics of distinct shapes and sizes can be curated with computer-assisted designs and engraved on clothes materials by utilizing laser machines.
➥ Signage Industry
There are different types of signs that are made from non-metals and metals bending towards the technology of laser engraving for developing the perfect impact on the mind of their viewers. In today's time, signs can be customized through laser software like Corel Draw and then transmitted to laser machines for generating high-quality signs or codes that pledge to make heads turn!
➥ Automotive and Aviation Industry
Laser technology is now being utilized for marking safety factor signs, production dates, serial numbers, texts, 2D digital barcodes, trademarks, and shift codes on various spare parts being utilized in this specific industry. It can be classified by its distinct features of rust prevention, anti-chemical agents, reliability, efficiency, and much more. These amazing features are establishing benchmarks for other industrial applications too.
➥ Healthcare Industry
In the healthcare sector, laser technologies are utilized in almost all areas. Its high-intensity & high-power laser beam is best suitable for tissue cutting; hence, a huge surgical instrument can surpass the conventional scalpel. In a routine manner, the laser is utilized for setting up the detached retina into the choroid. Many other serious eye conditions that are treated using lasers are diabetic rehabilitation and macular degeneration.
Few Special Characteristics Of Laser
(a) Uniform colour, this is so because the uniformity of its wavelengths is displayed in one colour.
(b) It is highly coherent as it does not spread in the surrounding atmosphere, for example - a light bulb. It has the ability to travel & cover long distances without getting affected or having reduced intensity.
(c) Tends to deliver spectral purity as the laser is intended that all the light wavelengths present in the beam are equal, which results in increasing the laser power.
(d) Over illumination because the laser light is much stronger than any general light as it is a mixture of radiation.
Now, the advancement in laser technology has completely changed the manufacturing industry in a better way. Lasers have contributed to revolutionising so many different regions of the manufacturing procedure, enabling accurate and precise manufacturing. Today, laser technology has taken considerable leaps from even just a few years back. In recent times, custom applications and advanced laser beams have allowed manufacturers to conduct & finish complex procedures more quickly and efficiently.
