940nm 140W Laser Fiber Coupled Diode Module
Output from fiber
Diode laser single emitter chip from Germany and submount from Japan
Standard fibre adapters or bare fibers
Single wavelength with/without indicator light or some wavelengths combining
Features:
Low current and high voltage working mode
This way greatly simplifies the power supply design, and the small working current can well meet the requirements of the pulse mode.
Applications:
pumping fiber laser, DPSSL, illumination and scientific research

Operating the product outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with the device must be employed such that the maximum peak optical power cannot be exceeded. A proper heat sink for the Device on thermal radiator is required, sufficient heat dissipation and thermal conductance to the heat sink must be ensured.
