laser cutting types

General Foam Laser System Considerations. Laser cutting words with counters makes text less legible. The laser is placed on one side and transmitted to the laser cutting … The gas mixture is usually carbon dioxide, nitrogen, hydrogen and helium. Gas laser cutting uses gases such as carbon dioxide or nitrogen. Crystal laser cutting is a process that uses lasers made from nd:YAG (neodymium-doped yttrium aluminium garnet) and nd:YVO (neodymium-doped yttrium ortho-vanadate). The neodymium (Nd) laser – used when high energy and low repetition are required. Broadly speaking, laser cutting can be divided into two types: laser fusion cutting and ablative laser cutting. Types of Lasers There are many types of lasers available for research, medical, industrial, and commercial uses. While working with thin materials, fiber lasers are the ideal solution. When you want a laser cutter and engraver that will look right at … Wavelength – The 10.6 micron wavelength is the best choice for laser cutting … More reflective metals like aluminium are more difficult to cut. One sub-type of fiber laser system is the MOPA, where pulse durations are adjustable. It is made a viable by electrically stimulating said carbon dioxide mixture. 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.  There are 3 types of lasers: CO2 (gas lasers), Fiber lasers and Nd:YAG or Nd:YVO (vanadate crystal lasers). We feel that these benefits make it the perfect solution, hence the reason that this is the approach that we take at SPI. Usually, higher power lasers are used on the industrial scale to cut out large sections of sheet metal or plastics, while lower power lasers … In those instances, fibre lasers … One of the mirrors is fully reflective and the other is partial, letting some of the light through. Failure to do this can cause the metal that you are working with to be oxidised. This makes the MOPA laser one of the most flexible lasers, which can be used for multiple applications. It is made a viable by electrically stimulating said carbon dioxide mixture. 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. Consequently, depending on the various structure of the laser cutting … The biggest benefit that a fiber laser provides is that it has a much longer service life than that of the previous two cutting types, coming in at around 25,000 hours. Your power, speed and other laser settings are going to vary depending on things such as thickness and the type of wood you are cutting. Their general wavelength is 1.064 micrometers, producing an extremely small focal diameter. We have covered these in more detail here: You are offered total control of the beam of your laser when you use one of our fiber lasers. Engraving is very similar to marking, with the difference being that the aim here is to create a deep, engraved mark, often used for applications such as creating barcodes. While leather is obviously one type of textile, … It can generally cut thin sheets aluminum and other non-ferrous metals. 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. It has many features when applied in the cutting process. Each use a different base material to stimulate the laser either electrically with a gas mixture or passed through physical diodes. These crystals are part of the solid state group, and the crystals allow for extremely high powered cutting. Specialize in CNC machining, 3D printing, urethane casting, rapid tooling, injection molding, metal casting, sheet metal and extrusion. Crystal laser cutting uses crystals made from nd:YAG or nd:YVO.
