Standing the Test of Time - The Great Wall of China and Laser Marking


In manufacturing, items made of metal often require engraving or markings for proper identification. Before the development of a commercial laser marking system, this identification process was usually achieved with labels, stamping, machine engraving, acid etching or ink printing. Then, in the mid-70s, advances in technology made it possible to create these markings using a focused beam of laser light.Before long, rapid refinements resulted in lasers that could be used with such accuracy that they could engrave not only letters and numbers, but even graphical images like company logos. Next came the ability to etch readable data such as barcodes and alignment marks or rulers, often critical components in manufacturing. It was hardly a surprise, then, when fiber laser marking machines gained a foothold in those instances when laser marking provided a clear financial and/or quality advantage over increasingly outdated methods of engraving and marking.

For decades, the only practical way to produce the 1.06 micron laser light (the precise wavelength required to etch metal) was with the YAG (Yttrium-aluminum-garnet)laser. But since YAG lasers are generally large, expensive, difficult to maintain and worst of all, require large amounts of energy to run their pre-requisite cooling systems, they are less than ideal for most commercial applications.
Then, about thirteen years ago, metal marking lasers underwent a revolutionary change. Fiber lasers, a relatively new technology, emerged as a viable alternative to YAG lasers for producing that high quality, 1.06 micron laser light critical to etching. Manufacturers were eager to source the best laser marking system to replace their outdated, often inefficient machines. Interestingly enough, of all the manufacturing centers using laser marking Los Angeles became one of the earliest adopters of this exciting breakthrough.

Fiber laser marking machines continue to offer sign if I can advantages in comparison to YAG lasers including smaller size, lower cost, reduced maintenance requirements, longer life and, you guessed it, lower electrical consumption. While a YAG laser requires 6000 to 8000 watts of electricity to produce 1.06 micron laser light, a fiber laser can achieve a comparable beam with only 200 watts of electricity (or roughly the power it takes to light up a couple of incandescent light bulbs). Equally impressive, while the YAG laser has a maximum output of twenty watts of high quality laser light, modern fiber lasers can produce up to 200 watts of high quality light, plus thousands of watts of slightly lower quality light as well.

And when you consider that fiber lasers can run off of any standard 115 Volt power outlet found in both commercial and residential sites, it is easy to see it was just a matter of time before Fiber Laser marking systems became relevant far beyond industrial applications.Asdemand began to increase, and more marking system manufacturers emerged, these systems became an even better value resulting in even more users, and so on. In short, fiber laser marking systems have become more of a commodity product and less of an overpriced, oversized industrial tool. 




Today the market for customers investing in product-marking laser systems spans from the home user to businesses of all sizes, including startups, and often those who never in a million years would have considered this type of purchase. In terms of market size, whereas total sales of YAG laser systems was in the hundreds of units per year, annual sales of Fiber Laser Marking systems is currently in the thousands of units. Innovative entrepreneurs, near and far,are using fiber laser marking systems in ways that were just not feasible or cost effective even ten years ago. 

Case in point; as first-time visitors to China a few years back, my wife and I set out to experience the iconic Great Wall. At one of the entrances stood a small booth selling souvenirs, including engraved pendants. Instantly I knew that these engravings could only have been made by laser and managed to convey this acknowledgement to the shopkeeper. With a smile, she led us behind the booth and proudly revealed the laser engraving machine which was, even at that moment,producing more pendants with which to restock her supply.And powering her laser marking system?A single, thin extension cord winding its way to an outlet positioned twenty yards away. Understanding how impossible this would have been if not for the advances in laser marking technology instilled in me a whole a new appreciation of just how far we’ve come from the days of the YAG not so long ago.

My company, Jimani, represents the culmination of a career in and passion for lasers; from working for the company that produced the first commercially-available lasers back in 1972 clear through to today, and at a time when demand for this technology only continues to grow. It is my privilege to offer the bestlaser marking system Los Angeles has to offer.
