Up to 600 mW Fiber Bragg Grating Stabilized Uncooled Mini-Butterfly 980 nm Pump Laser Modules
The Lumentum uncooled M12 mini butterfly Series 980 nm pump laser module uses a
number of revolutionary design steps and the very latest material technologies to
significantly improve scalability of the production process. The module meets the stringent
requirements of the telecommunications industry, including Telcordia GR-468-CORE for
hermetic 980 nm pump modules.
The M12 Series pump module, which uses fiber Bragg grating
stabilization to lock the emission wavelength, provides a noise-
free, narrowband spectrum, even under changes in temperature,
drive current and optical feedback. Wavelength selection is
available for applications requiring the highest performance in
spectrum control with the highest power available.

Note: Absolute maximum ratings are the maximum stresses that may be applied to the module for short periods of time without causing damage. Stresses in excess of the
absolute maximum ratings can cause permanent damage to the device. Exposure to absolute maximum ratings for extended periods of time or exposure to more than one
absolute maximum rating simultaneously may adversely affect device reliability. Specifications may not necessarily be met under these conditions.

Note: The tracking ratio is a measure of the front-to-back tracking when the output power is varied. On a plot of optical power versus back-face photocurrent, a straight line is
drawn between the minimum power (30 mW) and the operating power (Pop) points. The tracking ratio is defined as the ratio between measured optical power (shown as data
points on the plot) to the value derived from the straight line.

Safety and Operating Considerations
The laser light emitted from this laser diode is invisible and may be harmful to the human eye. Avoid looking directly into the fiber
when the device is in operation.
CAUTION: THE USE OF OPTICAL INSTRUMENTS WITH THIS PRODUCT INCREASES EYE HAZARD.
Operating the laser diode outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with this
component cannot exceed maximum peak optical power.
CW laser diodes may be damaged by excessive drive current or switching transients. When using power supplies, the laser diode should
be connected with the main power on and the output voltage at zero. The current should be increased slowly while monitoring the laser
diode output power and the drive current. Careful attention to heatsinking and proper mounting of this device is required to ensure
specified performance over its operating life. To maximize thermal transfer to the heatsink, the heatsink mounting surface must be flat
to within .001” and the mounting screws must be torqued down to 1.5 in.-lb.
ESD PROTECTION—Electrostatic discharge (ESD) is the primary cause of unexpected laser diode failure. Take extreme precaution to
prevent ESD. Use wrist straps, grounded work surfaces, and rigorous antistatic techniques when handling laser diodes.
