Data Sheet LBA-02 806nm Macrochannel Cooler Based Lateral Laser Diode Bar Arrays LBAxxxC-806-02 The Bookham LBA-02 macrochannel cooler based lateral laser diode bar array series has been designed to provide the high output power and high reliability required for side pumping of Nd:YAG solid-state lasers. 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 macrochannel package providing very high reliability in CW and pulsed (1-Hz type) applications. Features: • Horizontally arranged laser diode bars • Active macrochannel cooler (water-cooled) • 20W operating power per bar • Highly reliable single quantum well MBE structure • Telecom-grade AuSn mounting technology • Custom assembly options available • RoHS compliant Applications: • Solid-state laser pumping • Direct applications such as material processing • Illumination 1 Data Sheet Characteristics Parameter Symbol Typical Unit Pop 60 120 140 W Center Wavelength  λc 806 ± 3 nm Spectral Width (FWHM) ∆λ 3 nm Beam Divergence Parallel to Junction Perpendicular to Junction θ// θ⊥ 10 34 deg Polarization – TE Slope Efficiency ηD=Pop/(Iop-Ith) 1.1 W/A Conversion Efficiency H=Pop/(Vop×Iop) 45 % Operating Current Iop <30 A Operating Voltage per Bar Vop 2 V Operating Temperature Top 25 ± 5 °C Water Flow Qw 1 l/min Differential Pressure Drop per Bar Pw 0.1 bar CW Output Power LBA60W LBA120W LBA140W  Wavelength window / extended range available on request (780-1060nm).
