• 60 µm Step Index fiber
• Highly reliable
• Highly efficiency
The new high-brightness 2486 Series laser diodes offer up to 2 W from a 60 µm fiber
into 0.22 numerical aperture (NA) — perfect for thermal printing and other
applications that require high brightness and a long life. The dramatic increase in
output power, from the 60 micron fiber, will also enable new technologies such as
flexo and several material processing applications.
Taking advantage of the JDSU telecommunications design, the L3 package provides
the utmost in reliability and higher power handling capability required by the new
generation chips.
The L3 is available with convenient mounting plates and customer-selectable fiber
termination, including bare fiber, SMA, or ST connectors.

User Safety
Safety and Operating Considerations
The laser light emitted from this diode laser is invisible and may be harmful to the human eye. Avoid looking directly into the
diode laser or into the collimated beam along its optical axis when the device is in operation.
CAUTION: THE USE OF OPTICAL INSTRUMENTS WITH THIS PRODUCT WILL INCREASE EYE HAZARD.
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 optical power cannot be exceeded. CW diode lasers may be
damaged by excessive drive current or switching transients. When power supplies are used, the diode laser should be connected
with the main power on and the output voltage at zero. The current should be increased slowly while the diode laser output
power and the drive current are monitored.
Device degradation accelerates with increased temperature, and therefore careful attention to minimizing the case temperature
is advised. For example, life expectancy will decrease by a factor of four if the case is operated at 50°C rather than 25°C.
A proper heatsink for the diode laser on a thermal radiator will greatly enhance laser life. Firmly mount the laser on a radiator
with a thermal impedance of less than 0.5°C/W for increased reliability.
ESD PROTECTION - Electrostatic discharge is the primary cause of unexpected diode laser failure. Take extreme precaution
to prevent ESD. Use wrist straps, grounded work surfaces, and rigorous antistatic techniques when handling diode lasers.
