Laser Diodes
Linear Array CW Bars
970 t o 990 n m B a r s
Conduction-cooled, continuous wave (CW) laser diode bars, based on our aluminum-free technology give you high power and long-life performance in the 980nm range. The low beam divergence and narrow emission bandwidth of these devices allow you to use more of the laser emission efficiently. And standard wavelength options, matched to laser pumping requirements, make these bars easy to integrate.
As an added feature, an AR-coated, fast-axis collimating lens can be included on each linear array. The lens collimates the fast-axis beam divergence from to <1°FWHM.The lens makes applications in optical pumping and illumination, or integration into more complex optical systems easier.
Our diode growth and manufacturing facilities are equipped for highly reliable product and on-time delivery. That’s our commitment to you: High-performance devices featuring high reliability and delivered when you need them – whether it’s one device or 10,000.

OPERATING NOTES
•ESD precautions must be taken when handling unit.
•Negative current transients greater than 25 µA, and/or reverse voltages >3V, can destroy the unit.
•Unit requires an adequate heat sink. Failure to supply an adequate heat sink will destroy the unit.
•A dry environment should be provided when storing or operating a device with an open laser diode facet at temperatures below the ambient dew point. Failure to do so will cause condensation on the unit and can destroy it.
•Output powers in excess of specification will accelerate device aging.
•Operation at higher temperatures will accelerate device aging, increase threshold current and lower slope efficiency.
These components do not comply with the Federal Regulations (21 CFR Subchapter 1) as administered by the Center for Devices and Radiological health.Purchaser acknowledges that his/her products must comply with these regulations before they can be sold to a customer.
