Application context
Why this design is used
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
Communication
MDL-III-P-905: 905 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.
Spectrum analysis
MDL-III-P-905: 905 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.
System integration
Integration and compatibility
Use these checks to connect MDL-III-P-905 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Thermal management
- 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.
- Beam parameters at the output
- Transverse mode: Multimode · Beam divergence, full angle (mrad): <30
- 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.
- Mechanical envelope
- Dimensions of beam at the aperture (mm): ~10×10
- 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.
