New Diode Laser Product Line
SANTA CLARA, Calif., April 13 -- Coherent Inc. has introduced DuraLite, its first in a series of new diode laser products and the latest in its family of field-proven diode laser bars. The first available DuraLite product is an 810-nm, 50-W bar, an environmentally sealed and lensed conduction-cooled package (CCP), ideal for integration into graphic arts and direct-diode materials processing applications.
   DuraLite is housed in a sealed package to prevent contamination, and it is mounted on an industry-standard, conduction-cooled platform for ease of integration. The device also features several die attach enhancements, resulting in long, reliable operation. The company said it plans to develop a variety of DuraLite products to give customers several options for wavelength and output power.

Typical drive current and compliance voltage for the 50-watt device is less than 63 amperes and less then 1.8 volts. Spectral width is typically less than 4.0 nm, FWHM. Fast axis can be collimated to less than 5 mrad FWHM with near-diffraction-limited side lobe performance.

Coherent diode lasers are MBE-grown and feature an aluminum-free active area design, which nearly eliminates dark-line and spot defects, sudden failures and gradual degradation typically found in MOCVD-grown AlGaAs diode lasers. And since there is no aluminum in the active region of the device, there is no oxidation in the facets -- the leading failure mechanism with AlGaAs diode lasers.
