Series-level technical context
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.
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 Single Longitudinal Mode Single Frequency; confirm them on the order-specific datasheet.
Application context
Typical uses for this laser type, with the selection logic tied to the model record.
Single Longitudinal Mode Single Frequency: 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.
Single Longitudinal Mode Single Frequency: 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.
Single Longitudinal Mode Single Frequency: 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.
Single Longitudinal Mode Single Frequency: 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.

Choosing a laser
Which specifications decide the experiment, and which ones cost money without changing the result.
PhotonicsLinewidth, spectral width, RIN, M², and coherence length answer five different questions. Translate each into the units your experiment is designed in — and learn which ones not to pay for.

PhotonicsSingle-mode fiber does not preserve polarization. Pin the state, erase it with a scrambler, or maintain it in PM fiber — which one your measurement needs, and the response time and extinction ratio that decide it.
