Coherent Molectron Introduces Large-Area, Multi-Kilowatt PowerMax(TM) Laser Energy Probes



Santa Clara, Calif., February 27, 2003 - Coherent Molectron (Portland, OR) introduces several new additions to its PowerMax(TM) family of laser energy probes-the PM1K-100, the PM3K-100, the PM5K-100, and the PM5K-200. As the largest area, multi-kilowatt, water-cooled probes on the market, these new devices are ideal for measuring the energy output of diode laser bars, large cross-section laser beams, large diode laser arrays and high-divergence laser beams.

PowerMax probes measure the output of lasers ranging from 0.19 to 11 µm. The PM1K-100, PM3K-100 and PM5K-100 feature a 100-mm-diameter surface area; the PM5K-200 features a 200-mm-diameter surface area. PM1K-100 measures power levels as high as 1 kW with maximum intermittent power of 1.5 kW. PM3K-100 measures up to 3 kW with maximum intermittent power of 4 kW. PM5K-100 and PM5K-200 measure power levels as high as 5 kW, or intermittent power as high as 7.5 kW. Each device exhibits 1W power resolution. PowerMax devices also feature a maximum average power density of 26 kW/cm2 and a maximum pulse energy density of 0.6 J/cm2.

"Our new PowerMax probes provide a broad range of power measurement capabilities combined with the largest surface areas available today," said Burt Mooney, director of sales for Coherent Molectron, "This makes them a unique solution for measuring multi-kilowatt output of very large laser beams. And they're compatible with Coherent Molectron's PowerMax, 3sigma(TM) and EPM(TM) power and energy meters."

PowerMax probes feature Coherent Molectron's proprietary damage-resistant broadband coating. This provides significant performance improvements over large-area, black-painted probes. They're faster, more sensitive, and more resistant to scratches and laser damage across the spectrum, yet they maintain the desirable features of black paint-including broad, flat spectral response, low reflectance, and good spatial uniformity.

Originally founded in 1985 Molectron Detector Inc. was acquired by Coherent Inc. in December 2002. Coherent Molectron designs and manufactures custom and standard detectors, electronics and instruments for measuring laser power and energy. The acquisition further enhances Coherent's instruments and components portfolio, providing customers with the broadest range of laser measurement and control solutions.
