Laboratory measurement
YL-S-980/808/635/520/455: Laboratory measurement benefits from a stable, focusable source. 980 nm emission fixes the compatible coatings and detector response, while M², divergence and pointing stability should be confirmed for the intended beam path.
System integration
Integration and compatibility
Use these checks to connect YL-S-980/808/635/520/455 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Fiber delivery interface
- Fiber Core Diameter (um): 400, 600… · Fiber Connector: SMA905/ FC
- 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.
- Thermal management
- Operating temperature (℃): 10-30
- Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
