780 to 840 nm F-Packages Laser Diodes Fiber-Coupled Single-Stripe CW Devices Our high-power single-stripe laser diodes offer the simplest and easiest means to deliver laser light from a single stripe device to your application. With their compact and rugged design which feature a hermetic seal, they are the ideal choice for a host of industrial, thermal, graphic arts and scientific applications. Our fiber-coupled, single-stripe devices are available in a basic package, or with an integrated photodiode and thermistor assembly that monitors both the light output and the case temperature of the laser diode. These monitoring capabilities allow you to optimize laser performance and lifetime. A thermo-electric cooler (TEC) assembly is available as an external accessory. This `bolt-on' accessory lowers future replacement costs, while still offering the flexibility of temperature tuning.

Consult your Coherent representative. 3 FWHM. 4 The numerical aperture of the output beam is defined as the sine of the half-angle of the divergence cone that encircles 90% of the energy. 5 Values suggested are for operation of laser diode only. Operation of a TEC will require larger heat sink. 6 Momentary is defined as minutes. 7 780 to 840 nm 2 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. OPERATING NOTES * ESD precautions must be taken when handling unit. * Negative current transients greater than 25 A, 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 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. * Care should be taken to avoid back-reflections into the device. Failure to do so can destroy the unit. Coherent follows a policy of continuous product improvement. Specifications are subject to change without notice.
