Application context
Why this design is used
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
Laser phototypesetting
MSL-FN-561-AOM: 561 nm emission determines compatible optics, coatings and detectors for Laser phototypesetting. The catalogued beam parameter (<1.1) helps predict how the source will focus and propagate through the instrument.
Laser digital communication
MSL-FN-561-AOM: 561 nm emission must sit inside the fiber-component passband used for Laser digital communication; connector polish, fiber mode, linewidth and back-reflection tolerance should be specified as one optical interface.
System integration
Integration and compatibility
Use these checks to connect MSL-FN-561-AOM to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Thermal management
- Operating temperature (°C): 10-35
- Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
- Beam parameters at the output
- M²: <1.1 · Transverse mode: TEM00
- 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.
