Data Sheet 50W 806nm High Power Laser Diode Bar on Microchannel Cooler BAC50C-806-01/02 The Bookham BAC50C-806-01/02 laser bar on microchannel cooler series has been designed to provide the high output power and high reliability required for both solid-state laser pumping and 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 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 1.2mm laser diode bar • Active microchannel cooler (water-cooled) • 50W operating power • Highly reliable single quantum well MBE structure • Telecom grade AuSn mounting technology • Assembly option with Cu base and cover • RoHS compliant Applications: • Solid state laser pumping • Direct applications such as material processing • Printing • Medical 1 Data Sheet Characteristics Parameter Symbol Typical Unit CW Output Power Pop 50 W Center Wavelength λc 806 ± 3 nm ∆λ 3 nm dλc/dTop 0.26 nm/°C Beam Divergence (1/e2) Parallel to Junction Perpendicular to Junction θ// θ⊥ 10 34 deg Polarization - TE Threshold Current Ith 13 A Slope Efficiency ηD=Pop/(Iop-Ith) 1.1 W/A Conversion Efficiency H=Pop/(VopxIop) 45 % Series Resistance Rs 5 mΩ Operating Current Iop 60 A Operating Voltage Vop 2 V Operating Temperature Top 25 ± 5 °C Microcooler Flow Qw 22 ± 4 l/hrs Microcooler Differential Pressure Pw 0.7 bar Parameter Symbol Typical Unit Bar Width b 10 mm Resonator Length l 1.2 mm Number of Emitters n 25 - Emitter Spacing p 400 µm Emitter Width w 200 µm Fill Factor f 50 % Spectral Width (FWHM) Wavelength shift with temperature  Wavelength selectable, extended range on request (780-1060nm).
