Product Specifications
785nm Single Mode 14-pin
Butterfly Laser Diodes
Description
High brightness, high quality, and high reliability are the foundation of oursingle mode product line. Sheaumann’s785nm single mode laser modules
are available with up to 70mW of continuous output power from a 14-pin
butterfly packaged fiber. All chips are mounted on a 2.1mm COS within thepackage and come standard with an internal thermistor, TEC, andphotodiode. Sheaumann’s trademark laser chip design offers un-measurable
degradation and long lifetimes that make our chips among the most reliablein the industry today. Our 785 nm single mode line serves a broad range ofapplications including Raman Spectroscopy and optical data storage.
More options are available upon request. Please view our website formechanical drawings of our module packages.

SafetyESD Caution

ContactCaution: Laser light emitted from any diode laser
is invisible and may be harmful to the human eye.
Avoid looking directly into the diode laser aperturewhen the device is in operation. Note: The use of
optical instruments with this product will increase
eye hazard.

Always handle diode lasers with extreme care toprevent electrostatic discharge, the primary causeof unexpected diode failure. You can prevent ESD
by always wearing wrist straps, grounding all
applicable work surfaces, and following extremely
rigorous anti-static techniques when handlingTo request additionalinformation please

Operating Considerations

sales@sheaumann.com
Phone: (508) 970-0600

Operating the diode laser outside of its maximum ratings may cause device failure or a safety hazard.
Power supplies used with the component must be employed such that the maximum peak opticalpower cannot be exceeded. CW diode lasers may be damaged by excessive drive current or switchingtransients. When using power supplies, the diode laser should be connected with the main power onand the output voltage at zero. The current should be increased slowly while monitoring the diodelaser output power and the drive current. Device degradation accelerates with increased temperature,and therefore careful attention to minimize the case temperature is advised. A proper heat-sink for thediode laser on a thermal radiator will greatly enhance laser life.
