Thorlabs offers a full line of fiber pigtailed laser diodes using either single mode or multimode fibers. Our high quality alignment process includes multiple test and inspection points that ensure that the coupling efficiency is maximized. In addition, the input end of the fiber is cleaved at an 8° angle in order to minimize back reflections that can cause the output intensity to fluctuate. Single mode pigtails provide coherent fiber-coupled output from a laser diode. Multimode pigtails deliver higher power from the diode than single mode pigtails, but coherence is not maintained.
Please contact Technical Support if you would like a quote on custom pigtailed laser diodes or for a volume order.
Fiber Pigtailed Laser Diode Selection Guide
The table below lists basic information for each pigtailed laser diode, including a compatible mount and driver. See our Excel spreadsheet for a full list of compatible drivers. Please note that the compatible drivers listed also include a TEC controller (Thermo Electric Cooler). The TCLDM9 has a TEC element, while the SR9 series mounts do not. TEC control is recommended for pigtailed laser diodes as it stabilizes the output power and wavelength by keeping the diode at a constant temperature, which helps prolong the life of the diode. More information is available by clicking on the Specs tab above.
