Series-level technical context
Engineering context for a thin Single-Frequency Lasers record
This model has no standalone PDF and only a small number of model-specific rows. The values below are traceable context from 12 wavelength-near single-frequency lasers records; they define the parameters to qualify, but are not substituted for an order-specific datasheet.
Typical operating fields in the series
- • Output / average power: 1~50 mW
- • Output / average power: 1~40 mW
- • Output / average power: 1~650 mW
- • Operating mode: CW
- • Spectral linewidth: <0.06 nm, <0.03
Beam-quality tolerance context
Nearby series records state M²: <1.5, M²: <1.1, M²: <1.3, and Beam divergence, full angle (mrad): <1.5. These are series context, not guaranteed values for Narrow Linewidth; 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.
Cell sorting
Narrow Linewidth: 637 nm emission determines compatible optics, coatings and detectors for Cell sorting. Beam quality, divergence and pointing stability should be checked against the experiment geometry.
Spectrum analysis
Narrow Linewidth: 637 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.
Flow cytometry
Narrow Linewidth: 637 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.
