Data Sheet 50W 9xxnm 30% Fill Factor High Power Laser Diode Bar on Passive Cu Block Cooler BPC50C-9xx-01 The Bookham BPC50C-9xx-01 30% fill factor laser diode bar on passive cooler series has been designed to provide the high brightness and and reliability required for both collimated solidstate 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 diode bars are mounted on an expansion matched CuW submount onto a Cu block package providing very high reliability in CW and pulsed (1-Hz type) applications. Features: • Mounted 10mm x 1.2mm laser diode bar • Passive 1" x 1" Cu block cooler • 30% fill factor (150µm emitter / 500µm pitch) • 50W operating power • Highly reliable single quantum well MBE structure • Telecom grade AuSn mounting technology • Standard wavelengths at 915nm, 940nm, and 980nm (others available on request) • RoHS compliant Applications: • Collimated solid-state laser pumping • Direct applications such as material processing • Printing • Medical 1 Data Sheet Characteristics Parameter Symbol Typical Unit Pop 50 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⊥ θ⊥ 8 26 60 deg Polarization – TE – Threshold Current Ith 5 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 55 A Operating Voltage Vop 1.5 V Operating Temperature Top 25 ± 5 °C CW Output Power Center Wavelength  BPC50C-915-01 BPC50C-940-01 BPC50C-980-01 Spectral Width (FWHM) Wavelength Shift with Temperature Beam Divergence Parallel to Junction (90% of Power) Perpendicular to Junction (FWHM) Perpendicular to Junction (90% of Power)  Reduced wavelength window / extended range available on request (900-1060nm) Bar Dimensions 2 Parameter Symbol Typical Unit Bar Width b 10 mm Resonator Length l 1.2 mm Number of Emitters n 19 – Emitter Spacing p 500 µm Emission Width w 150 µm Fill Factor f 30 % Data Sheet Passive Cu Block Cooler Dimensions (mm) 24.9 Side 7.93 7.52 11.19 14.19 Front Beam Height .39 Ø4 Top 9 2-56 UNC 6.1 3 3.18 18.54 14.28 12.3 22 13.97 24.9 Ø2.7 Data Sheet RoHS Compliance Bookham is fully committed to environment protection and sustainable development and has set in place a comprehensive program for removing polluting and hazardous substances from all of its products.
