The system consists of the cutting head, fiber collimator, linear drive with position measuring, and an internal, low-noise height sense system that is insensitive to cutting plasma or piercing debris. The head works with all leading fiber-delivered laser systems up to 4 kW with wavelengths of 1064/1080 nm.
Rotary converting platform
Web converters and manufacturers who produce multi-layer construction packaging, parts, and components for the medical, pharmaceutical, electronic, label, automotive, electronic display, and RFID markets may want to consider Preco's (Somerset, WI; www.precoinc.com) Rotary Converting Platform (RCP) series. The RCP is a continuous process-step-independent, servo-driven system where each rotary station is electronically geared to allow adjustments for optimizing tension as well as making registration correction at every processing point. Preco's direct drive gearing into the RCP ensures greater die cutting accuracy by reducing the potential for backlash or swathing in the gearing.
Quasi-CW UV laser
Two new quasi-CW UV lasers from Coherent Inc. (Santa Clara, CA; www.Coherent.com) deliver the highest power currently available for products of this type, according to the company. Specifically, the Paladin Advanced 355-10000 and Paladin Advanced 355-16000 are mode-locked, frequency tripled, diode pumped, solid-state lasers that offer 10W and 16W of power, respectively, at 355 nm (at 80 MHz). In addition to high power, the lasers deliver a high quality, TEM00 beam (M2<1.2) with excellent stability and low noise characteristics (<1% rms from 10 Hz to 2 MHz). Additionally, both models offer improved operating efficiency over their lower power predecessors, resulting in a reduced cost per watt in terms of both purchase price and operating expense. And, because these new lasers share nearly all of the same mechanical and optical characteristics as the lower power models, there is a straightforward migration path for system builders looking to take advantage of their increased power and efficiency.

Q-switched 800W DPSS YAG laser
Lee Laser (Orlando, FL; www.leelaser.com) has demonstrated the performance of a new, 800W CW Nd:YAG laser that is capable of Q-switched performance well in excess of 600 W average output power at 10 kHz pulse rate. The compact optical resonator of this laser utilizes existing Lee Laser diode-pumped technology, plus some new technology that the company has developed internally. A major design feature of this laser is the short pulse width capability comfortably less than 70 ns at 10 kHz, without risk of damage to internal optical elements. Pulse instability less than 8% peak-peak has been demonstrated. This new high-power laser at 1064 nm will give both systems integrators and end users alike the high average power and high peak pulse power that is required for emerging micromachining technologies. Among the applications to be pursued will be deep marking and engraving, cutting of hard materials such as tungsten carbide and polycrystalline diamond for machine tool manufacture, flat panel display manufacture, and laser patterning for LCD manufacture.

In addition, the product combines the company's Ethernet-based LEC-1 Controller, a power supply, and interface hardware (laser extension and I/O boards) into a slim and lightweight 1U rack-mountable enclosure.
Laser marking station
Benefits of the TruMark 5000 NEW from TRUMPF (Farmington, CT; www.us.trumpf.com) include longer traverse paths and higher travel speeds in the linear axes, which are available as a complete module that can be installed by hand in just a few steps; a more powerful suction unit that enables marking processes with strong materials removal; and enhanced ergonomics for greater operator comfort and optimal efficiency. The system has a Z-axis travel path that is 200 mm longer than the TruMark 5000. Now 19.6 in (500 mm) long, the traverse path offers even greater flexibility in marking larger components in a variety of sizes. In addition, the laser system can be equipped with two linear axes (300 mm) as well as a rotating axis. This allows the TruMark Station 5000 to precisely adapt to each marking task. The linear axes have a fundamentally new control concept with an integrated motor driver, which facilitates retrofitting the workstation. The travel speeds of the X-and-Y axes are three times faster, which leads to less time between two marking cycles when the workstation is loaded with several workpieces at once. The axes can be correctly positioned manually with the push of a button. The stronger suction unit takes into account the increased laser outputs of the marking lasers in the TruMark Series 3000, 5000 and 6000, all of which can be integrated into the workstation.
