Flow cytometry
3 75: 375 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.

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.
