System integration

Integration and compatibility

Use these checks to connect FL-618-LN-L to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Fiber delivery interface
Fiber connector: FC/APC
Match the listed connector and fiber mode exactly; SMA905, FC/PC and FC/APC are not interchangeable, and a single-mode launch requires mode-field as well as numerical-aperture matching.
Thermal management
Cooled method: Air cooled or Water cooled · Operating temperature (℃): 15-30
Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
Beam parameters at the output
Transverse mode: TEM00 · M2: <1.1
Size the downstream optics from the stated beam diameter and divergence rather than from the aperture of the housing, and confirm the polarisation state before specifying isolators or polarising optics.
