Power is restricted in most jurisdictions not to exceed 5 mW. The forumula for depth of field is DOF = 2.5 x wavelength x ( focal_length / beam_diameter ) 2 for the G100 laser it calculates to: DOF = 0.027 * (focal_length / beam_diameter) 2 The optics for the laser The beam delivery system is composed of a bend mirror, a processing head, a cut quality enhancer and circular polarizer, and a beam expander.

Depending on the machine you are considering you will have power options for your laser source that range from 30-120 watts for CO2 laser tubes. The differences in the operating cost are based on the maintenance and the efficiency of the style of laser being used. Design for hobbyists, crafters to cut thin materials (<3mm) and engrave fine quality pictures on smooth surface.Our TruCUT 90W CO2 Laser is suitable for laser marking, laser cutting and laser engraving which is the ideal choice of laser cut on thin plates include perspex, softwood etc, Our TruCUT 100W CO2 Laser is suitable for leather carving and hollowing-out or embossing, Our TruCUT 120W/130W CO2 Laser is suitable for the cutting of die-cutting plates, Our TruCUT 150W - 180W CO2 Laser, which outputs between 150W and 180W of power, #1 Laser Generating Device is mounted on Gantry on Flatbed model, therefor the length of cutting table won't effect the cutting efficiency.

The final piece of the puzzle for laser processing is the cutting speed.

Disclaimer: the above data is gathered from various sources which may not be accurate, please contact us for correction. There is no simple answer on the thickness a laser system can cut. For beams that are not 100% uniform, the peak power/energy density will be higher. Notes: Tophat calculations are for ideal tophat laser beams. This is only a very basic estimate. We have compiled this guide for the laser system that we sell, which gives you a good idea of all kinds of materials that a laser can mark, engrave, drill and cut from … #2 There is no absorption problem of laser light from either a Nd:YAG (1.06 microns) or CO2 (10.6 microns) laser in nitrogen, or in air without contaminants. The longer of the lens' Focus Length the longer the Depth Of Field ( DOF ) which increases the cutting thickness. Please note, laser device size increases as power increases, Silicon Mirror Plated with Multi-layer Dielectric Film K9 Crystal Glass Gold-Plated Laser Reflecting Mirror
Please be sure to refer www.epiloglaser.com for a sample list of some of the materials that can be cut/not cut.These values will not be true for all materials.

Chart #3 illustrates the different efficiencies for the various cutting lasers.

A laser pointer or laser pen is a small handheld device with a power source (usually a battery) and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light. The power of the laser source is measured in watts. Although the MPE can be exceeded, the risk of injury is low. With a material like anodized aluminum, for example, you would run your 30watt machine at 100% speed, so having a higher power laser tube in this case would not yield any additional benefit in this material.

Generally speaking, lower power CO2 laser tubes will be able to process the same materials, with the same detail and quality as higher-power laser tubes, but higher-power laser tubes will allow you to 1) cut deeper in a single pass, and 2) engrave faster in These values can vary significantly due to different types of materials, different focal lenses, alignment of optics, etc.
