LightMachinery is the world's leading manufacturer of Transversely Excited Atmospheric Carbon Dioxide (TEA CO2) lasers. Our laser team pioneered the development of TEA CO2 laser technology and has been designing carbon dioxide lasers and laser marking and drilling systems for over 30 years.


The LightMachinery IMPACT Series high power lasers are designed for 24/7 materials processing and drilling of non-metallic materials. These pulsed lasers are optimized for precision processing and drilling of non-metallic materials.


The LightMachineary LaserMark Series is the ultimate in marking reliability, from beer labels and gelcaps to miniature electronics components. These lasers are designed for on-line marking and coding, creating perfect, crisp images on your products 24/7.


Coherent Diamond C-Series CO2 lasers offer reliability with more than 50,000 operating hours, along with superior beam quality and stability. These lasers are ideal for a wide range of applications from marking and engraving to material processing. They are a compact option with an integrated RF power supply. Maximum output power ranges from 20 to 40 watts, and can be controlled through pulse width modulation (PWM).


In the manufacturing industry, engineers are constantly developing solutions made possible by high-power lasers. They are mainly used to mark, clean, texture, weld, and cut materials faster and meet short cycle times in production lines.


Different types of lasers are needed for different applications. Based on their gain medium, lasers are classified into five main types: gas lasers, solid-state lasers, fiber lasers, liquid lasers (dye lasers), and semiconductor lasers (laser diodes).


The main difference that determines the type of materials each laser can process is the wavelength. A fiber laser usually has a wavelength of 1,060 nm while CO2 lasers have wavelengths in the 10,600 nm range. In general, fiber lasers have many advantages over CO2 lasers.


Fiber lasers are best suited for high-contrast markings like metal annealing, etching, and engraving. They produce an extremely small focal diameter (resulting in intensity up to 100 times higher than a CO2 system), making them the ideal choice for permanent marking of serial numbers, barcodes, and data matrix on metals. Fiber lasers are widely used for product traceability (direct part marking) and identification applications.


One big plus is fiber lasers are maintenance-free machines, and they have a long service life (our lasers have a minimum of 100,000 operating hours). They are also smaller than CO2 lasers. Plus due to the high electrical efficiency of fiber lasers, they use significantly less power than CO2 lasers, resulting in huge cost savings for cutting applications.


The cost of a fiber laser system will greatly vary depending on your applications. Industrial fiber lasers systems for demanding environment like we do usually start at $40,000 and can go up to $1,000,000 for high-power laser-cutting machines. The power usually ranging from 20 W to 6,000 W will have the largest impact on price.


CO2 laser marking is ideal for a wide range of non-metallic materials including plastics, textiles, glass, acrylic, wood, and even stone. They are used in pharmaceutical and food packaging as well as the marking of PVC pipes, building materials, mobile communications gadgets, electrical appliances, integrated circuits, and electronic components.


Unfortunately, CO2 lasers use significantly more power than fiber lasers, resulting in a higher cost of operation. For instance, a high-power CO2 laser and chiller will consume roughly 70 kW when operating on maximum power. A similarly powered fiber laser consumes approximately 18 kW.


The cost of CO2 lasers tends to be less than fiber lasers. The price for CO2 laser marking systems usually ranges between $35,000 and $80,000. Again, the power (which usually ranges between 20 W to 150 W) will influence the cost.


Although each laser does have its strengths and distinct use cases, CO2 is an older technology and fiber lasers are gaining market fast as the technology advances. With the speed benefits, almost half of the operating costs and three to four times greater throughput than CO2 lasers, the financial gains that can be got from using fiber lasers can be game changing.


The latest Mira 7 and Mira 9 professional benchtop CO2 lasers include the safety of a fully interlocked case and keyed ignition, thus transforming the Mira into a Class 1 laser, the highest safety rating possible. The new design preserves the best features from the previous generation, such as the Clean Pack Design and cutting edge high speeds, while adding some finishing touches, like a fire resistant tempered glass lid, gas shocks and rubber seals.


Great emphasis was placed on improving the cutting capabilities and the various components required to do so. The entire work table has been overhauled and replaced with a motorized blade table that is fitted with a downdraft exhaust system similar to what you would find in our Nova Pro Series. The exhaust fan and air assist pump have also been upgraded to help with improving airflow and increasing cutting efficiency. Equipped with a built-in fan cooled water chiller (Mira 7) or a vapor compression water chiller (Mira 9), the Mira Pro models are ready to take your laser engraving and cutting abilities to the next level.


High-speed linear rails help to harness the full cutting potential that comes with having a larger laser tube; while traversing when the laser is off can reach speeds of up to 1500 mm/sec, resulting in a significant reduction in cycle times.


Flying optics (fig 2) is the most common and recognized option for beam delivery. By mounting small mirrors on a movable X and Y axis, a laser beam can be transferred across a very large plane. However, this reduces processing speed significantly as the X and Y movements are no where near the initial speed of light you start out with.


Plano-convex is the simplest, least expensive lens shape and is typically what comes standard in most CO2 lasers. They are used in applications where achieving the smallest spot size is not critical, or at relatively long focal lengths when more complex shapes would not be beneficial.


Focal lenses are usually referred to by their focal distances. As the focal distance is increased, so does the distance from the laser head to the work surface and the tolerance in which the the laser beam remains concentrated enough to burn effectively. Focus tolerance is particularly important for cutting applications.


Conversely, as the focal distance is decreased so does the diameter of the spot size. The smaller the spot size, the higher the resolution you can achieve and the greater the intensity of the laser beam becomes. Smaller focal distances are most often used for detailed engraving and fine cutting applications where having a high focus tolerance is not as important.


Venting your CO2 laser outdoors is certainly the least expensive route to take. However, there is a lot more to it than just sticking a hose out the window. You must decide a number a things like where to install the exhaust fan, how to run the ducting, how to replace the air being sucked out of the room, how to maintain the desired temperature in the room and finally where to point the end of the exhaust duct.


A good laser exhaust system is one that is quiet, removes smoke and odors, helps in reducing sparks and flaming and creates a safe working environment. The result of having such a system will be an improvement in engraving and cutting quality, with both a decrease in smoke residue on your work pieces and the need for cleaning inside the laser system.


The simplest and most responsible way to ventilate a CO2 laser is with a fume extractor. Fume extractors are basically tightly sealed cabinets containing an exhaust fan and a series of various filtration media divided into stages. The fumes are sucked out from the laser, pushed through each of the filtration stages and then spit back out into the room where they are once again safe for the environment and for everyone in it. There is no need to worry about ducting, replacement air, temperature control or harming the environment.


However, the cost of replacement filters now becomes a consumable item that will add to your cost of ownership. Therefore, it's important that you choose the proper fume extractor for your CO2 laser. The exhaust fan in the fume extractor will need to remove a certain volume of air (CFM) from the CO2 laser's cabinet. In addition, the combination of filter layers and types of chemicals used, will determine how effective and how efficient your fume extractor will operate. Matching your fume extractor to your laser's cabinet size and to your unique application(s) is fundamental to maximizing the performance of the laser and the life of your filters. 041b061a72
