Data Sheet 120W 9xxnm High Power Laser Diode Bar on Microchannel Cooler BAC120C-9xx-01/02 The Bookham BAC120C-9xx-01/02 50% fill factor laser diode bar on microchannel cooler series has been designed to provide the increased brightness and reliability required for pumping next generation solid-state disk and fibre lasers, and for direct applications. 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 CuW submount onto a water-cooled microchannel package providing very high reliability in CW and pulsed (1-Hz type) applications. Features: • Mounted 10mm x 2.4mm laser diode bar • Active microchannel cooler (water-cooled) • 120W operating power • Highly reliable single quantum well MBE structure • Telecom grade AuSn mounting technology • Assembly option with Cu base and cover • Standard wavelengths at 915nm, 940nm, and 980nm (others available on request) • RoHS compliant Applications: • Solid-state disk and fiber laser pumping • Direct applications such as material processing • Printing • Medical 1 Data Sheet Characteristics Parameter Symbol Typical Unit Pop 120 W λ c915 λ c940 λ c980 915 ± 10 940 ± 10 980 ± 10 nm ∆λ 3 nm dλc/dTop 0.3 nm/°C θ// θ⊥ 7 26 deg Polarization – TE – Threshold Current Ith 14 A Slope Efficiency ηD=Pop/(Iop-Ith) 1 W/A Conversion Efficiency H=Pop/(Vop×Iop) 60 % Series Resistance Rs 5 mΩ Operating Current Iop 140 A Operating Voltage Vop 1.5 V Operating Temperature Top 25 ± 5 °C Microcooler Flow Qw 22 ± 4 l/hrs Microchannel Cooler Differential Pressure Pw 0.7 bar CW Output Power Center Wavelength  BAC120C-915-01/02 BAC120C-940-01/02 BAC120C-980-01/02 Spectral Width (FWHM) Wavelength Shift with Temperature Beam Divergence Parallel to Junction (90% of Power) Perpendicular to Junction (FWHM)  Reduced wavelength window / extended range available on request (900-1060nm).
