Application context
Typical uses for this laser type, with the selection logic tied to the model record.
YL-I-455: 454 nm emission can be matched to the absorption or excitation band used in Flow cytometry. The stated stability or noise figure (<2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.
YL-I-455: 454 nm emission can be matched to the absorption or excitation band used in DNA sequencing. The stated stability or noise figure (<2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.
YL-I-455: 454 nm emission can be matched to the absorption or excitation band used in Medical imaging. The stated stability or noise figure (<2%, <1%) helps keep measured intensity changes attributable to the sample rather than source drift.
YL-I-455: 454 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.

Technical FAQ
Fiber Core Diameter (um): 100, 200, 400, 600, 0.22NA · Fiber Connector: SMA905, FC/PC optional. 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: Air cooled · Operating temperature (℃): 0-30. Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
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.
