fill factor bars 40W 18FFx2mm TE 60W 18FFx2mm TE-Plus Bar Geometry 18FFx2mm 1 Wavelength specifications are based on testing of unmounted bars under low current, low duty cycle, short-pulsewidth test conditions. Contact factory for details. 2 <=80W CW bars are qualified on a Coherent conduction-cooled package (CCP) operated at full power and 25°C. Customers' results may vary as a function of packaging stress, packaging thermal resistance, operating power, and temperature. 3 >=100W CW bars are qualified on a Coherent water-cooled package (WCP) operated at full power and 25°C. Customers'...

5 300W and 500W QCW bars are qualified as half-bars on a Coherent conduction-cooled package (CCP) operated at half the rated full-bar power at the indicated nominal conditions and 25°C. Customers' results may vary as a function of packaging stress, packaging thermal resistance, operating power, and temperature. 6 Specifications listed here apply at beginning of life. Operating current at end of life is 120% the operating current at beginning of life. 7 Please consult the factory for any requirements not listed, including the following options: - Centroid wavelength and spectral width requirements...
