Application context
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
MLL-III-975-SM: 975 nm emission can be matched to the absorption or excitation band used in Medical imaging. The stated stability or noise figure (<2%, <1%, <0.5%) helps keep measured intensity changes attributable to the sample rather than source drift.

Technical FAQ
Fiber type: SM fiber, PM fiber optional · DIODE LASER AT 975nm Fiber Core diameter: 4-9μm, 0.12NA. 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.
Cooled method: Conduction · Operating temperature (°C): 10-35. Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
Transverse mode: TEM00 · M2 after fiber: ~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.
Share wavelength, operating mode, output power or pulse energy, linewidth or pulse width, delivery, control, and safety requirements and we will qualify the matching configuration and lead time.
