Application context
Why this design is used
Typical uses for this laser type, with the selection logic tied to the model record.
Spectrum analysis
MSL-R-1342: 1342 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.
Measurement
MSL-R-1342: Measurement benefits from a stable, focusable source. 1342 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (TEM00) informs waist size and propagation.
Flow cytometry
MSL-R-1342: 1342 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<3%, <2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.
System integration
Integration and compatibility
Use these checks to connect MSL-R-1342 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Thermal management
- Cooled method (water cooled): WCH-580 · Operating temperature (°C): 20-30
- 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: <1.3
- 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.
