Coherent Launches New Diode Laser Product Line



DuraLite Products Feature Sealed Package, High-Power and Long Lifetime

Santa Clara, Calif., April 13, 2004 - Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) introduces DuraLite(TM), the first in a series of new diode laser products and the latest in its extensive family of field-proven diode laser bars. The first available DuraLite product is an 810 nm, 50W bar, an environmentally sealed and lensed conduction-cooled package (CCP), ideal for integration into graphic arts and direct-diode materials processing applications.

DuraLite features a combination of high-power output and unmatched reliability based on a proven design. The device 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 DuraLite also features several die attach enhancements, resulting in long, reliable operation. The company 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.

Founded in 1966, Coherent, Inc. is a Standard & Poor's SmallCap 600 company and a world leader in providing photonics-based solutions to the commercial and scientific research markets.
