Data Sheet 9W 940nm High Power Single Emitter Laser Diode on Submount SES9-940-01 The Bookham SES9-940-01 single emitter laser diode series has been designed to provide the high output power, high coupling efficiency and high reliability required for pumping next generation fiber lasers and for other high power laser diode 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 single emitter laser diodes are p-side down mounted on an optimized submount providing very low thermal resistance. Features: • 3.6mm x 0.4mm laser diode • 90µm wide emitter • 9W operating power (p-side down mounted) • Highly reliable single quantum well MBE structure • Standard wavelength at 940nm (other available on request) • RoHS compliant Applications: • Fiber laser pumping • Material processing • Printing • Medical 1 Data Sheet Characteristics Parameter Symbol Typical Unit Pop 9 W λc 940 ± 10 nm ∆λ 4 nm dλc/dTop 0.3 nm/°C θ// θ⊥ 8 29 deg Polarization – TE – Threshold Current Ith 500 mA Slope Efficiency ηD=Pop/(Iop-Ith) 1.0 W/A Conversion Efficiency H=Pop/(Vop x Iop) > 50 % Series Resistance Rs 0.03 Ω Operating Current Iop 9.5 A Operating Voltage Vop 2.2 V Operating Temperature Top 25 ± 5 °C CW Output Power Center Wavelength  Spectral Width (FWHM) Wavelength Shift with Temperature Beam Divergence (FWHM) Parallel to Junction Perpendicular to Junction  Reduced wavelength window/extended range available on request (900-1070nm).
