Application context
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
MDL-XF-975: Measurement benefits from a stable, focusable source. 975 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (Multimode) informs waist size and propagation.
MDL-XF-975: 975 nm emission must sit inside the fiber-component passband used for Communication; connector polish, fiber mode, linewidth and back-reflection tolerance should be specified as one optical interface.
MDL-XF-975: 975 nm emission sets the excitation and detector-band choice for Spectrum analysis; linewidth and wavelength stability determine how cleanly weak spectral features can be separated from the laser line. The listed beam characteristic (Multimode) also controls focusing and collection geometry.

Technical FAQ
Cooled method: Air cooled · Operating temperature (℃): 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: Multimode · Beam divergence, full angle (mrad): <3.0. 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.
Dimensions of beam at the aperture (mm): ~5×8. Verify the housing drawing and bolt length before designing a mount. A laser head rarely carries a table thread itself, so the adapter between it and an M6 or 1/4"-20 grid is part of the specification.
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.
