The design of the Bystronic (Hauppauge, NY; www.bystronicusa.com) Bylaser 6000W resonator now incorporates advanced mirror detection systems; End Mirror Sensor (EMS) and Output Coupler Sensor (OCS). These new features will automatically monitor the conditions of the two most important mirrors in the resonator and will shut down the resonator in the case of a fault. This is a key feature of maintaining continuous process safety, especially when running an automated lights-out operation. The system also now incorporates a Magnetic Blower (MAG), which provides a wear-free and maintenance-free turbine blower which requires no lubrication or other maintenance tasks.

Horizontal stacked arrays

DILAS (Mainz, Germany; www.dilas.com) offers a broad range of horizontal stacked arrays, from two through thirteen bars available at 808nm and 940nm. In a compact and easy-to-integrate package, the linear arrays deliver high-power output while offering simplified water-cooling requirements. The low thermal resistance of the package and efficient cooling permits CW operation at highest output power levels, or QCW operation at up to 50% duty factor. These arrays can be arranged in either a side-by-side arrangement or any other custom pattern, in order to deliver maximum power density needed for the application.

Digital laser scanner for welding

Meta Vision Systems (Oxfordshire, UK; www.meta-mvs.com) has launched a 3D digital laser scanner for use in automated welding equipment. Designated DLS300, the sensor uses triangulation, but is based on a scanning spot rather than a stripe, solving the two main problems of stripe-based triangulation. First, it is easy to implement effective automatic gain control to compensate for reflectivity changes. Second, imaging is via a linear charge coupled device, which only looks at the region of interest and is not affected by reflections. Additional benefits of the scanning technology include a programmable field of view and independence of the sensor's depth of field from the width of field.

Regenerative amplifiers

High Q Laser's (Hohenems/Bregenz, Austria; www.highQlaser.at) new series of ultra compact pico- and femtosecond regenerative amplifiers were designed to meet a maintenance interval of 12 months and a life time of 5 years. The available power of the all-in-one amplifiers is 30 W for the picoREGEN UC-INDUSTRIAL with a pulse duration of 12ps and 8 W for the femtoREGEN UC-INDUSTRIAL with a pulse duration of 350fs. These ultra-fast amplifiers are well suited to be integrated as OEM products, due to their compact size with a footprint of 78 cm x 34 cm, their all-in-one controller, and their ability for full remote control and signal read out. Combining high power and high repetition rates these products are perfect tools for a wide range of applications in nano- and microprocessing such as solar cell structuring and scribing, thin film ablation, hole drilling, and precision cutting.

Optomechanical design software

TracePro 5.0 optomechanical design software from Lambda Research Corp. (Littleton, MA; www.lambdares.com) provides an all-new interface for modeling optical sources. The user is now able to define and manage spectral data for each unique source and to combine different source types in a single ray trace. This yields significant time savings to any design process that involves multiple sources or source alternatives and fluorescence. New analysis capabilities include flux versus Optical Path Length (OPL) or Time of Flight (TOF). New simulation advances include reverse ray traces and luminance ray traces with blackbody and gray body sources. And new add-in utilities assist in quickly and accurately creating and optimizing properties. Inputs can include data from physical measurements, manufacturers' data, and industry standards.

IPG Photonics Corp. (Oxford, MA; www.ipgphotonics.com) announced a new line of cost-effective fiber lasers specifically designed for cladding, brazing, and annealing applications in the automotive, aerospace, oil, and heavy industries. The new YLS-CL series are available operating at 2, 3, or 4 kilowatts, feature a choice of round or square fiber deliveries with various output fiber core sizes and beam shapes, come with a three-year full warranty, and are extremely compact. According to the company, the process fibers are much more flexible and reliable in comparison to delivery fibers typically used in direct diode systems.

Designed for heavy duty industrial needs like welding, soldering, or cutting, the 300W laser 9xx nm from Lumics GmbH (Berlin, Germany; www.lumics.com) is based on individual, hermetically sealed diodes, single emitter technology. These diodes are carefully packed in an industrial sealed housing on a small footprint to work in an integrated system or machine. The overall design is fiber based. The laser is actively cooled by tap water. Red pilot beam, monitor diodes, and thermistors provide all necessary process feedback info. The output fiber is 800µm and is terminated by a high power connector. This robust and reliable laser head is designed to provide flexibility for various industrial tasks.

Controllers for galvanometer scan systems

SCANLAB's (Puchheim,Germany; www.scanlab.de) RTC 5 is available as a PC interface board and as a PC/104-Plus module. Compared to its RTC 4 predecessor, the RTC 5 supports a 16x higher positioning resolution of 20 bits with the new SL2-100 data transfer protocol. “Processing on the fly” users will appreciate the 16x expanded virtual working field with 24-bit vector coordinates. The inclusion of short list commands enables users to access peripheral interfaces without interrupting polygonal traversal (while the laser remains on). Freely configurable list memory has been increased to one million positions, a portion of which is write-protectable. Innovative commands for automatic laser control enable the implementation of automatic (position/speed/vector-dependent) laser-power readjustment during execution of vector and arc commands. This can produce more consistent line widths, or be used to intentionally vary the power applied along a vector in welding applications. Multiple RTC 5 boards can be used in a single PC and multiple applications can reciprocally access the boards (multiprocessing). Moreover, multiple RTC 5 boards can be synchronized in master/slave mode.

2W laser marking system

The UM-1 ultra-compact, 1064nm laser marking system from RMI Laser (Lafayette, CO; www.rmilaser.com) is intended for cost effective permanent marking and engraving applications. Priced less than $20,000, this 2-watt, diode-pumped, Nd:YAG laser marking system is easily integrated into existing operations and is ideal for small-scale production environments. The UM-1 is air-cooled and requires no consumables making it energy efficient and maintenance free. The unit delivers consistent, clean marks on metals, plastics, silicon, graphite, carbide, ceramics, composites, and electronic parts. Applications include high-resolution bar codes, UID, Data Matrix, alphanumerics, batch numbers, 2D symbols, text, logos, and photo quality images.
