19 January 2004 Madison, WI Lightwave -- Alfalight, Inc. has expanded its portfolio of fiber-coupled laser products with its 20-W Combined Power Module (CPM-20). The CPM-20 produces a high-brightness multimode output beam by combining the output of seven high-power emitters.

The compact, easy-to-integrate package operates from a standard, low-current power supply. The modular CPM-20 provides a bright, reliable optical power source that is ideal for industrial, marking, defense, telecommunications and medical laser applications, according to the company.

"The innovative package design for this multi-emitter module provides operational redundancy, making the CPM-20 extremely reliable and long-lasting," said Tom Earles, chief technical officer of Alfalight. "In combination with available specialty optical fibers, the CPM-20 forms the foundation of a modular fiber laser. It is the ideal optical engine to power laser applications that include fiber and DPSS laser pumping, laser soldering, marking, and welding."

The CPM-20 provides over 20 W of fiber-coupled 915-nm light with exceptional brightness as well as beam uniformity; the output fiber has a 125-micron core with a 0.45 numerical aperture (NA). The rugged package incorporates the laser sources, fiber combiner, and protection circuitry, and is designed to mount easily to a system heat sink or chassis. The unit requires a current of 5 A at approximately 15 V.

The CPM-20 (part number ALC1-915) is currently offered at a wavelength of 915 nm for $5,000 in 1-5 piece quantities; wavelengths of 808, 955, and 976 nm are available upon request. The CPM-20 will be available to ship in volume quantities at the end of Q1 2004. Contact the manufacturer for volume pricing.
