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: 1-350 mW
  • Output / average power: 1~350 mW
  • Output / average power: 350~3500 mW
  • Operating mode: CW
  • Spectral linewidth: <1 MHz

Beam-quality tolerance context

Nearby series records state M²: <1.2, Beam divergence (mrad): <1.5, Beam divergence, full angle (mrad): <1.2, and Beam divergence, full angle (mrad): <1.0. These are series context, not guaranteed values for Narrow Linewidth; 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

Narrow Linewidth: 457 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

Narrow Linewidth: 457 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

Narrow Linewidth: 457 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.

Measurement

Narrow Linewidth: Measurement benefits from a stable, focusable source. 457 nm emission fixes the compatible coatings and detector response, while M², divergence and pointing stability should be confirmed for the intended beam path.
