Laser Cutting Machines

Coherent Inc. has expanded its AVIA family of lasers with new models having green output and which reportedly offer an unmatched combination of power, reliability and compact size for a range of precision materials processing applications. The new AVIA NX products are q-switched, diode-pumped, solid-state lasers that deliver up to 65W of average power at 532 nm from a laser head that measures less than two feet (587 mm) in length.

Electro Scientific Industries Inc. (ESI), Shanghai, China, recently introduced the Garnet adaptable laser micromachining platform for high-volume cutting, marking, drilling or engraving applications, according to a Feb. 16 company news release. The Garnet platform is said to compliment ESI's current micromachining portfolio delivering lower cost of ownership—specifically to meet the need for larger format materials among manufacturers in China.

Coherent Inc., Santa Clara, Calif., recently enhanced its series of large-area, high-speed PowerMax-Pro laser detectors to enable power measurement of laser beams of up to 375W continuously, 600W for shorter durations, and modulated peak powers as high as 15 kW in intermittent (long-pulse) operation, according to the company. The PowerMax-Pro detectors, introduced in 2014, are based on Coherent's proprietary thin-film sensor technology that combines the broad wavelength sensitivity, dynamic range and laser damage resistance of a thermopile with the response speed of a semiconductor photodiode.

FOBA Laser Marking + Engraving's Y-Series ytterbium fiber lasers are for marking parts made of metal, plastic and other materials. A scan head vision system for in-process imaging combines validation and verification prior to and directly after laser marking. The system's modular platform consists of nine compact, flexible, fiber marking lasers that offers a range of power from 2w to 50w and pulse widths from 1.5 to 200 nanoseconds.

Optodyne Inc., Rancho Dominguez, Calif., a maker of laser measurement, calibration and compensation systems, recently introduced a new and improved laser calibration system—the MCV-500H and MCV-5000H. The MCV-500H and MCV-5000H laser calibration system is a basic system for linear displacement measurement, the company said in a news release issued Dec. 17, 2015.

The new TruPrint 1000 LMF 3D printer works like a selective laser melting 3D printer, using a powder bed process to build 3D parts by laying down a thin layer of metal powder materials onto the build surface while a 200-watt laser fuses the layer of powder along the contour of the part being printed.

Custom fabricated zinc sulfide (ZnS) optics that are water-clear with minimum scatter and provide high transmission capabilities across a broad wavelength spectrum for a variety of military applications are being introduced by Laser Research Optics.

Coherent Inc. announces new, higher power, higher brightness 780-830 nm and 975 nm diode laser components for industrial applications.

MC Machinery Systems says the new eX-F Series fiber laser combines the best of both worlds: the top notch construction of the popular eX Series CO₂ lasers and the power and reliability of a Mitsubishi's finest fiber resonator.

The new affordable laser named thePico series, designed and manufactured by Bright Solutions, has novel pulsewidths and SLM output for micromachining, ablation, scribing, lidar, non-linear optics and many other industrial, medical, military and R&D tasks.

Coherent Inc. has expanded the company's fiber laser offering with an all new platform capable of delivering output powers to 4 kW and beyond.

A new generation of carbon monoxide (CO) lasers from Coherent Inc. promise enhanced processing characteristics for materials processing applications ranging from glass cutting and via drilling, to fractional skin resurfacing.
