940nm L4S Laser Diode Module from Lumentum
These 940nm multimode pump laser diode modules from Lumentum are offered in a fiber coupled, high reliability L4S package.
Continuous Design Evolution Delivers A Highly Reliable Device
The L4S-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 pumps for the multi-mode pump market. Key applications include fiber laser pumping, materials processing and graphic arts.
Heat Sinking for Lumentum L4 Packaged High Power Pumps The L4S-94010-120E 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.
