Thus, fiber lasers have a far longer lifecycle than the other two types and they can produce strong and stable beams. One can enhance the power of the CO2 beam by boosting the oxygen content, however this can be risky in inexperienced hands or with a machine unsuitable for such enhancements. The laser beam is focused to form a light spot with high energy density. Laser cutting has been around since the 60’s but now it’s as relevant as it has ever been due to its growing usage within industrial processes. Solid state lasers have lasing material distributed in a solid matrix, e.g., the ruby or neodymium-YAG (yttrium aluminum garnet) lasers. There are three main types of lasers used for cutting, we have explained these in greater detail below: Gas laser cutting, most often known as C02 laser cutting, is completed using a carbon dioxide mixed laser. The term “Laser” is an acronym for “Light Amplification by Stimulated Emission of Radiation”. The best woods for laser cutting are Basswood, White Pine, Alder, Cherry, Oak, Baltic Birch Plywood, Balsa and Cork. More reflective metals like aluminium are more difficult to cut. The neodymium-YAG laser … There are 3 types of lasers: CO2 (gas lasers), Fiber lasers and Nd:YAG or Nd:YVO (vanadate crystal lasers). The biggest drawback to a crystal laser machine is that it is an expensive piece of kit, made up from just as expensive pump diodes. The drawback of these machines is that they can be expensive, not just because of their initial price but also because they have a life expectancy 8,000 to 15,000 hours (with Nd:YVO4 being having a typically lower one) and the pump diodes can net a very hefty price. This makes the MOPA laser one of the most flexible lasers, which can be used for multiple applications. Laser cutters can cut all types of metals, from mild steel to stainless and also non-ferrous metals. Drilling is another common process that can be used with a fiber laser. Since laser cutting … Cut off other non-metals. When comparing the two Nd:YVO exhibits higher pump absorption and gain, a broader bandwidth, broader wavelength range for pumping, a shorter upper‐state lifetime, a higher refractive index and lower thermal conductivity. The first type of laser used in cutting sheet metal, the CO 2 laser generates a beam of energy within a mixture of carbon dioxide, helium, and nitrogen gas. Crystal laser-based cutting also has roots dating back to 1964, being created in the same laboratories as gas lasers; Bell Labs. While leather is obviously one type of textile, … Laser cutting textiles is a newer option. With a wavelength of 1.064 micrometres, it’s useful for a huge range of applications, from medical and dentistry to military and manufacturing.  There are 3 types of lasers: CO2 (gas lasers), Fiber lasers and Nd:YAG or Nd:YVO (vanadate crystal lasers). However, this is less so the case for materials over 20 mm although, a more expensive fiber laser machine that can work with over 6 kW could do the trick. Each use a different base material to stimulate the laser either electrically with a gas mixture or passed through physical diodes. It has several similarities to the crystal process, in the fact that optical fiber also belongs to the solid state group, and it also has a wavelength of 1.064 micrometres. Laser cutting is a kind of non-contact machining with high energy and density control. Narrower kerf widths 4. Laser cutting is one of the most main process to make sheet metal parts. However, Nd:YVO does not allow for pulse energies as high as Nd:YAG and the laser life lasts for shorter periods. A CO2 laser runs electricity through a gas mixture-filled tube, producing light beams. The CO 2 laser is suited for cutting, boring, and engraving. Laser cutting words with counters makes text less legible. These crystals are part of the solid state group, and the crystals allow for extremely high powered cutting. The kind of material that a laser can cut depends on the type of laser and the specific machine’s power. The type of laser defines what type and thickness of material it can cut through, because different laser types have different power ranges. Due to the similar sizes, yttrium, gadolinium or lutetium ions can be replaced with laser-active rare earth ions without strongly affecting the lattice structure needed to produce the beam. Crystal laser cutting uses crystals made from nd:YAG or nd:YVO.

This type of laser is capable of cutting thicker materials at higher speeds than other laser types, such as fiber lasers, and produces less of a micro-burr along the cut … Most laser cutters prefer soft woods that do not have a distorted, … Marking is one process that can also be completed with a fiber laser, and involves the melting of a surface layer of a material to leave a mark behind. Fiber Laser cutting equipment can cut stainless steel below 4mm, and can cut up to 8 ~ 10mm thick stainless steel in laser beam if add oxygen. A laser cutter is used to cut a sheet of metal. The Nd:YVO4 crystal has been incorporated with high NLO coefficient crystals (LBO, BBO, or KTP) to frequency-shift the output from the near infrared to green, blue, or even UV which gives it a ton of varying functions. Gas laser cutting, most often known as C02 laser cutting, is completed using a carbon dioxide mixed laser. It uses a large amount of energy generated by a laser, concentrated on a very small area, in order to cut or engrave a material. When gas laser cutting was first invented in 1964, it wasn’t powerful enough to cut metals. A crystal laser machine has a shorter life expectancy than other machines on the market, at around 8,000 to 15,000 hours, meaning it could cost you more over a longer period of time, not to mention if you have to replace the expensive pump diodes should they break. As with any process or type of technology, laser cutting has developed over the years not only as an alternative process to other conventional forms of cutting, but to also include several types and techniques itself. There are several different types of lasers typically used in industrial cutting systems: CO 2 or Nd lasers being the most common. Using Stencil fonts that have bridges connecting counters to the exterior of the type solves this issue, but the number of Stencil … We mainly talk about CO 2 lasers, fiber lasers and vanadate lasers. The final type of cutting is with fiber lasers, the process that we use here at SPI with our Continuous Wave Fiber and Pulsed Fiber Lasers. They can manage intensities 100 times higher than that of CO2 lasers with the same amount of average power. Fiber lasers can be in continuous beam, quasi- or offer pulsed settings giving them different functionalities.
