Laser Cutting

Amada Miyachi America Inc. announces the availability of the updated LMWS pulsed fiber laser welding system, a highly configurable, compact unit designed for lean manufacturing. The system features a versatile high-power, high-speed laser, available in 20- to 70-watt (W) powers for welding metals and plastics.

Laser Institute of America (LIA), the professional society for laser applications and safety, announces its release of the LIA Guide to High Power Laser Cutting. In the guide, students, engineers and scientists alike will gain a more in-depth understanding of the science behind laser cutting. Written by a team of specialists led by industry experts Dr. John Powell and Dr. Dirk Petring, this 136-page guide is a comprehensive resource that touches on all features of laser cutting machines and materials.

A 1 kW (average power) pulsed fiber laser from Coherent | Rofin offers a high beam quality for this power level, thus enabling high throughput, precision ablation for a variety of industrial and solar applications. Specifically, the FP 010 delivers a maximum pulse energy of 100 mJ, at pulse widths between 10 ns and 100 ns, and with repetition rates ranging from 10 kHz to 30 kHz.

A full line of ZnSe (zinc selenide) focusing lenses that are optimized for use with steel cutting lasers up to 4 kW and suitable field replacements by users is available from Laser Research Optics. Laser Research Optics CO2 Laser Lenses come in plano-convex and –meniscus configurations in 1” to 2” OD sizes with thicknesses ranging from 0.250” to 0.380”.

A new 120W CO2 laser from Coherent offers a 30 percent better power/volume ratio than most competitive lasers in this class, enabling the construction of more compact laser-based systems for space-constrained, industrial applications. Additionally, the Cx-10 offers a unique combination of performance and reliability features to deliver both superior processing results and lower total cost of ownership.

MidOpt announces the availability of three new imaging filters primarily intended for blocking unwanted near-infrared light. Filters include: SP635 Absorptive Visible Shortpass/Near-IR Block Filter, SP644 Near-IR/Mid-Red Dichroic Block Shortpass Filter, and AB555 Acrylic Absorptive Near-IR/UV-Block Visible Bandpass Filter.

Amada Miyachi America Inc. announces the availability of the LMF70-HP, an addition to its LMF series of lasers. The 70 watt (W) LMF70-HP is ideal for welding small components and thin metals up to 0.01-inch (0.25 mm) thick. It is particularly well suited for welding battery tabs to cans (two thin sheets of metal), but can also weld thin wires (thermocouples, guidewires, etc.). In addition to welding, the unit is capable of engraving, deep engraving and cutting of metal, plastic welding and general-purpose, high-speed marking.
