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 31 nearby configurations on the same source-product record; they define the parameters to qualify, but are not substituted for an order-specific datasheet.
Nearby series records state M²: <1.2, M²: <1.1, Beam divergence, full angle (mrad): <1, and Beam divergence, full angle (mrad): ~2.5×0.2. These are series context, not guaranteed values for YL-I-405; confirm them on the order-specific datasheet.
Application context
Typical uses for this laser type, with the selection logic tied to the model record.
YL-I-405: 405 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<0.5%) helps keep measured intensity changes attributable to the sample rather than source drift.
YL-I-405: 405 nm emission can be matched to the absorption or excitation band used in DNA sequencing. The stated stability or noise figure (<0.5%) helps keep measured intensity changes attributable to the sample rather than source drift.
YL-I-405: 405 nm emission can be matched to the absorption or excitation band used in Medical imaging. The stated stability or noise figure (<0.5%) helps keep measured intensity changes attributable to the sample rather than source drift.
YL-I-405: 405 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.
Share wavelength, operating mode, output power or pulse energy, linewidth or pulse width, delivery, control, and safety requirements and we will qualify the matching configuration and lead time.

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.
