Data Sheet Preliminary 80W 9xxnm High Power Very High Brightness Laser Diode Bar on Microchannel Cooler VAC80C-9xx-01/02 The Bookham VAC80C-9xx-01/02 laser diode bar on microchannel cooler series has been designed to provide highest brightness and reliability required for industrial applications. With the emission width only a third of conventional laser diode bars, the optimized angular power distribution is most suitable for applications requiring smallest spot size or lowest fiber core diameter. The proprietary E2 front mirror passivation process, developed at our Zurich site, prevents Catastrophic Optical Damage (COD) to the laser diode facet even at extremely high output powers. The laser diode bars are mounted on an expansion matched submount onto a water-cooled microchannel package providing very high reliability in CW and pulsed (1-Hz type) applications. Features: • Mounted 3.6mm x 3.6mm laser diode bar • Active microchannel cooler (water-cooled) • 80W operating power • Highly reliable single quantum well MBE structure • Telecom grade AuSn mounting technology • Standard wavelength at 915nm, 940nm, and 980nm (others available on request) • RoHS compliant Applications: • Solid-state and fiber laser pumping • Direct applications such as material processing • High-quality beam shaping applications • Printing • Medical 1 Data Sheet Characteristics Parameter Symbol Typical Unit Pop 80 W λc915 λc940 λc980 915 ± 10 940 ± 10 980 ± 10 nm ∆λ 4 nm dλc/dTop 0.3 nm/°C θ// θ⊥ 9 29 deg Polarization – TE – Threshold Current Ith 11 A Slope Efficiency ηD = Pop/(Iop-Ith) 1.1 W/A Conversion Efficiency H = Pop/(VopxIop) 60 % Series Resistance Rs 5 mΩ Operating Current Iop 84 A Operating Voltage Vop 1.6 V Operating Temperature Top 25 ± 5 °C Watercooler Flow Qw 22 ± 4 l/hrs Microchannel Cooler Differential Pressure Pw 0.7 bar CW Output Power Central Wavelength  VAC80C-915-01/02 VAC80C-940-01/02 VAC80C-980-01/02 Spectral Width (FWHM) Wavelength Shift with Temperature Beam Divergence Parallel to Junction (90% of Power) Perpendicular to Junction (FWHM) Notes:  Reduced wavelength window/extended range available on request (900-1060nm).
