Application context
Why this design is used
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
Medical measurement
MRL-U-671: Medical measurement benefits from a stable, focusable source. 671 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (TEM00) informs waist size and propagation.
Spectrum analysis
MRL-U-671: 671 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 (TEM00) also controls focusing and collection geometry.
System integration
Integration and compatibility
Use these checks to connect MRL-U-671 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Thermal management
- 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.
- Beam parameters at the output
- Transverse mode: TEM00 · M2: <1.2
- 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.
