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 18 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: 1-150 mW
  • Output / average power: 1-300 mW
  • Output power (mW): 1-1500
  • Operating mode: CW
  • Optical noise: <0.5%

Beam-quality tolerance context

Nearby series records state M²: <2, <1.5, M²: <1.2, Beam divergence, full angle (mrad): ~1.0, and Beam divergence, full angle (mrad): ~2.5×1.0. These are series context, not guaranteed values for Long Coherent Length; confirm them on the order-specific datasheet.

Optical integration schematic

  2. Step 2Safety shutter and optional optical isolator
  3. Step 3Beam steering, expansion or fiber-launch optics
  4. Step 4Experiment input with wavelength-matched coatings

Application context

Why this design is used

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

Flow cytometry

Long Coherent Length: 488 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.

DNA sequencing

Long Coherent Length: 488 nm emission can be matched to the absorption or excitation band used in DNA sequencing. Power stability and beam pointing should be confirmed because both affect quantitative image or fluorescence intensity.

Medical imaging

Long Coherent Length: 488 nm emission can be matched to the absorption or excitation band used in Medical imaging. Power stability and beam pointing should be confirmed because both affect quantitative image or fluorescence intensity.

Spectrum analysis

Long Coherent Length: 488 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.
