SANTA CLARA, Calif., Sept. 12, 2006 -- The new Matrix line of diode-pumped solid-state (DPSS) lasers from Coherent Inc. combines the performance and reliability of solid-state lasers with several design and manufacturing innovations. These new features deliver an optimum solution for cost-effective volume OEM integration, the company said. The infrared (1.06 µm) Q-switched lasers deliver 10 W of average power with excellent beam quality (M2 = 1.1).

CoherentMatrix.jpgSeveral models of the Matrix offer repetition rates, RMS noise levels and costs targeted at specific applications segments. Among these are a 10-kHz model optimized for engraving plastics, metals and other materials that are problematic for carbon-dioxide lasers. A 30-kHz version is designed for trimming active and passive circuit components (resistors, crystals, etc.) in microelectronics. A 350-kHz version combines the high repetition rate and extremely low noise (<1% RMS) required for precision, high-throughput applications, such as memory repair and disk texturing.

These factory-sealed lasers are designed for integration within specialized tools and equipment by OEMs. This integration is simplified by the small footprint of the Matrix platform, the laser's low power requirements and a choice of air cooling or closed-loop water cooling. Expected lifetimes of the pump diodes are in the 20,000-hour range, based on the use of the company's AAA (aluminum-free active area) diode material.

GLOSSARY
diode
A two-electrode device with an anode and a cathode that passes current in only one direction. It may be designed as an electron tube or as a semiconductor device.
matrix
With respect to television, that part of a color television circuit that combines the I, Q and Y signals, and changes them into single red, green and blue signals applied to the picture-tube grids.
