System integration
Integration and compatibility
Use these checks to connect MRL-FN-721-H 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
- Transverse mode: TEM00 · M2: <1.5
- 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.
