DPSS Industrial Laser Modules - Laser Pointers and Solid State Diode Lasers

DPSS laser modules are the most used types of lasers for both industrial applications as well as personal enjoyment. The term DPSS, diode pumped solid state, refers to the state of the laser diode as it produces its laser beam through its collimated laser crystal. The complexities of designing and modding lasers of this nature have pushed scientists and light engineers to design brighter and more powerful solid state lasers, from hand held pointers to large box laser units.

There is clear value in the use and application of certain laser products, no more so than in the use of industrial laser modules. Lasers are relatively new technology, and for this reason, there is constant advancement and improvement of both the design and performance of lasers for their specific said use. The most common forms of industrial laser use include laser engraving, laser cutting, laser burning, and more. The versatility of condensed laser light allows for a broad spectrum of valuable scientific and industrial based applications. Various laser beam color frequencies can be utilized, as each different wavelength will produce a different color, visible or invisible, that can then be tuned to be geared towards a specific use.

But what is the real difference between DPSS laser modules and your average laser pointer? There are clear differences both in design and in performance capabilities. For instance, dpss laser diodes require an external power source and must therefore be plugged directly into a walls electrical source or be attached to a laser "battery" for ignition. This poses a few problems if you are looking to perform any experiments in the outdoors or in the field, where plugging the laser in is impossible. The industrial laser diodes are usually far larger than laser pens as well, because many of them require internal thermoelectric cooling because of the heat produced by the solid state laser beam.

Laser pointers, on the other hand, are extremely convenient in size and shape, but may lack the same performance consistency as large boxed diodes. Also, industrial laser applications are nearly impossible for a laser pointer because the high-tech device must be manually engaged and even held in one's hand. This can make cutting and engraving all but impossible, not to mention most laser pointers are not capable of producing enough mW (milliwatt) power to complete the desired industrial task. Pointers are more geared towards laser presentations, astronomy, and even just simply laser pointer fun. There is no question that industrial dpss laser modules have found a strong standing amongst many industrial professionals around the globe, be sure that you are working with certified laser modules from a reputable dpss industrial laser retailer. You would not want to sacrifice a few dollars to buy a laser online that simply won't accomplish what you are looking for.

James has been utilizing DPSS industrial lasers since they first began to be mass produced around the globe. He has developed unique laser use methods and prefers DPSS industrial laser modules from certified laser provider thinklasers.com

Laser Metal Cutting

Laser cutting is a modern technology in which a high-powered laser is directed at the desired surface to cut different shapes and forms. The material usually burns or melts, leaving a high-quality surface finish. Since there is no direct contact between the laser and the surface in use, the level of precision and accuracy in the laser cutting process is much more as compared to conventional methods.

Due to its accuracy and efficiency, laser cutting is used to cut a wide variety of materials. Metal is one such common application. Since ancient times, metals have been widely used for a number of purposes. From weapons and ornaments to construction and packing material, the importance of metals in our day-to-day lives cannot be denied. Today, with the development of fiber optics and information technology, metals have gained a highly specific role. Since conventional processing methods cannot suffice all these modern requirements, laser cutting is being extensively used in metal processing.

Apart from the normal CO2 laser used in most processes, metal cutting employs the use of three other processes, namely Oxygen cutting, Nitrogen cutting and Sublimation cutting. The oxygen process creates more heat on account of the reaction between the metal and the gas. The extra heat assists in the cutting process. On the other hand, when an inert gas like nitrogen is used for cutting the metal, additional power is required.

Since metals are good conductors and reflectors of heat, the intensity of the laser needs to be altered, depending upon the nature of the metal. The laser beam is guided around the metal surface to get the desired shape.

Laser metal cutting offers several advantages over the other processes such as plasma cutting, water-jet cutting and flame cutting. The laser process is not only faster than the other methods, but also offers unparalleled levels of accuracy and quality. The chances of damaging the surface being cut are also reduced.

Laser Plastic Cutting

Laser-aided cutting has brought about a revolution in the manufacturing industries. These high-powered optical beams are used to cut through a variety of materials such as metal, wood, glass and plastic. The laser is directed at the required surface and moved around to cut the material in the desired shape. Laser cutting gives a finer finish to the end product as compared to conventional cutting methods.

A typical laser beam is about 1/5th of a millimeter in width and has an intensity of 1000 to 2000 watts. Most laser cutting machines are integrated into a CAD/CAM system that helps the user design the end product on a computer before implementing it on the work piece.

Laser cutting devices are proving beneficial in a wide array of industries. The plastic industry is no exception. These optic powered devices are used to cut precise shapes into plastic or acrylic sheets. The lasers can be used to cut plastics of varying thickness by simply altering the intensity of the beam. Lasers are not only used to cut through plastics but also help engrave on various surfaces.

Laser plastic cutting machines bring precision and accuracy to the entire process. Since most machines are fully automated, they can perform complex cutting operations at high-speeds. The laser plastic cutting machines can also be used to cut polymers, polycarbonates and other synthetic materials such as polyesters and rubbers.

The laser cutting method uses a non-contact approach when cutting the material. Due to this, the wear and tear associated with conventional methods is absent, preventing the product from any damage and deformation. The laser process also delivers a finish quality unmatched by any other process.

When using laser plastic cutting machines, care should be taken to avoid the use of flammable plastics such as PVCs. These materials cannot cope with the heat generated by the laser and get damaged easily.
