Application context
Typical uses for this laser type, with the selection logic tied to the model record.
MLL-K-457-SM: 457 nm emission can be matched to the absorption or excitation band used in Medical imaging. The stated stability or noise figure (<3%, <2%, (<1% optional)) helps keep measured intensity changes attributable to the sample rather than source drift.
MLL-K-457-SM: 457 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<3%, <2%, (<1% optional)) helps keep measured intensity changes attributable to the sample rather than source drift.
MLL-K-457-SM: 457 nm emission can be matched to the absorption or excitation band used in DNA sequencing. The stated stability or noise figure (<3%, <2%, (<1% optional)) helps keep measured intensity changes attributable to the sample rather than source drift.
MLL-K-457-SM: Measurement benefits from a stable, focusable source. 457 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (TEM00 (single mode fiber output)) informs waist size and propagation.

Technical FAQ
Fiber core diameter: 3.5um,0.10NA · Fiber connector: FC/APC. Match the listed connector and fiber mode exactly; SMA905, FC/PC and FC/APC are not interchangeable, and a single-mode launch requires mode-field as well as numerical-aperture matching.
Cooled method: Water cooled · Operating temperature (°C): 10-30. Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
Transverse mode: TEM00 (single mode fiber output) · M2: <1.1. Size the downstream optics from the stated beam diameter and divergence rather than from the aperture of the housing, and confirm the polarisation state before specifying isolators or polarising optics.
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.

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.
