Data Sheet 8W/7W 9xxnm High Power Single Emitter Laser Diode on Submount SESx-9xx-01 The Bookham SESx-9xx-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 • 8W/7W operating power (p-side down mounted) • Highly reliable single quantum well MBE structure • Standard wavelength at 915, 940, 960, and 975nm (other available on request) • RoHS compliant Applications: • Fiber laser pumping • Material processing • Printing • Medical 1 Data Sheet Characteristics Parameter CW Output Power SES8-915-01 SES8-940-01 SES8-960-01 SES7-975-01 Center Wavelength SES8-915-01 SES8-940-01 SES8-960-01 SES7-975-01  Symbol Typical Pop915 Pop940 Pop960 Pop975 8 8 8 7 λc915 λc940 λc960 λc975 915 940 960 975 ± ± ± ± W 10 10 10 10 nm ∆λ 4 nm dλc/dTop 0.3 nm/°C θ// θ⊥ 8 29 deg Polarization – TE – Threshold Current I th 400 mA ηD=Pop/(Iop-Ith) 1.0 W/A H=Pop/(Vop x Iop) > 50 % Series Resistance Rs 0.03 Ω Operating Current SES8-915-01 SES8-940-01 SES8-960-01 SES7-975-01 Iop915 Iop940 Iop960 Iop975 8.5 8.5 8.5 7.5 Operating Voltage Vop 1.9 V Operating Temperature Top 25 ± 5 °C Spectral Width (FWHM) Wavelength Shift with Temperature Beam Divergence (FWHM) Parallel to Junction Perpendicular to Junction Slope Efficiency Conversion Efficiency  Reduced wavelength window/extended range available on request (900-1070nm).
