Mitsubishi Laser (Wood Dale, IL) has expanded its line of CO2 lasers with the LV laser series. The LV laser system is offered in three sizes: 2512 (4 x 8), 3015 (5 x 10) and 3718 (6 x 12). Features include enhancements to the company's patented cross-flow resonator, full network and automation capability and a single-piece, ultra-rigid Dianite cast machine system. The new AC smart servo direct-drive system provides improved cutting accuracy and high-speed positioning. The programmable high assist gas pressure automatic function eliminates the need to make manual settings. Dross reduction control command uses real-time advanced NC program "look ahead" technology to determine maximum processing speed based on material, thickness and part geometry. The minimal warm-up time, 45 seconds from resonator off to full output power, increases optimization and productivity. The 20 CF (cross-flow) resonators offer 2000 watts of output power and the 35 CF offers 3600 watts. Also new with this series is the company's Diamond Path beam delivery system, which automatically adjusts the beam path to create a consistent beam travel distance from the resonator to the processing head.

Therma-Vent heat sinks from Thermacore International Inc. (Lancaster, PA) utilize enhanced fin technology to increase the heat sink surface area and create turbulent airflow to disperse heat more efficiently. The company's new rolled and slit fin technology maximizes surface area, thus increasing the flow of heat from the chip into the local ambient air. Brazed attachment of the fins to the base ensures mechanical and thermal joint integrity and minimizes the chance of cracks forming over time, as can happen with an epoxy bond.

FAP diode laser
Coherent Inc., Semiconductor Division (Santa Clara, CA) has introduced a line of high-power 40W fiber array packaged (FAP) bars in the 780 to 815 nm wavelength range. The products are intended for direct-diode thermal applications and as a pump source for neodymium-doped solid-state lasers. The laser energy from the fiber-coupled diode laser is efficiently coupled into an 800-micron multimode fiber bundle, terminated with an SMA 905 connector. Typical drive current for the 40W FAP is less than 55 amps. Spectral width is typically less than 4 nm FWHM, and beam divergence is less than 0.14 NA, encompassing 90 percent of the energy.
