Product Overview:

830nm Laser Diode Module from Lumentum

The new high-brightness 2486-L4 series laser diodes offer up to 2 W from a 60-μm fiber into 0.22 numerical aperture (NA)—ideal 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, also enables new technologies such as flexography, illumination, and several material processing applications.

Continuous Design Evolution Delivers A Highly Reliable Device

The L4-Series fiber-coupled laser diodes are the natural evolution of the highly successful L2 and L3 laser module packages. These devices were designed to be cost effective a wide range of applications. Key applications include computer-to-plate printing, flexographic printing, and graphic arts.

Heat Sinking for Lumentum L4 Packaged High Power Lasers
The L4-2486-006 package was designed to allow the use of either air cooling or water cooled thermal management. To avoid device degradation due to run-away heat build-up, the case temperature should be actively controlled and kept in a safe operating temperature window. A proper heat sink for the diode laser on a thermal radiator will greatly enhance the life of the laser.

Laser Lab Source offers a pre-configured heat sink which has been optimized for the L4 package. It comes pre-drilled with the correct mounting hole placement and has a TEC based cooling plate with a small fan to remove the waste heat. In addition to the mount, the current source and TEC controller unit which is compatible with the 12W laser is also available. Please contact us for more information on controlling and cooling high power Lumentum laser diodes.
