Coherent introduces DuraLite, 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 810nm, 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 50watt device is less than 63amperes and less than 1.8volts.
Spectral width is typically less than 4.0nm, FWHM.
Fast axis can be collimated to less than 5mrad 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.
