Series-level technical context

Engineering context for a thin CW Lasers record

This model has no standalone PDF and only a small number of model-specific rows. The values below are traceable context from 5 nearby configurations on the same source-product record; they define the parameters to qualify, but are not substituted for an order-specific datasheet.

Typical operating fields in the series

  • Output / average power: 1~15 mW
  • Output / average power: 1~5 mW
  • Operating mode: CW
  • Power stability (rms, 4 hours ± 3°C): <2%, <1%, <0.5%

Beam-quality tolerance context

Nearby series records state Beam divergence, full angle (mrad): <2.0. These are series context, not guaranteed values for MDL-III-1370DFB-SM; confirm them on the order-specific datasheet.

Application context

Why this design is used

Typical uses for this laser type, with the selection logic tied to the model record.

Communication

MDL-III-1370DFB-SM: 1370 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-1370DFB-SM: 1370 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.

Measurement

MDL-III-1370DFB-SM: Measurement benefits from a stable, focusable source. 1370 nm emission fixes the compatible coatings and detector response, while M², divergence and pointing stability should be confirmed for the intended beam path.

Flow cytometry

MDL-III-1370DFB-SM: 1370 nm emission can be matched to the absorption or excitation band used in Flow cytometry. Power stability and beam pointing should be confirmed because both affect quantitative image or fluorescence intensity.
