Application context
Typical uses for this laser type, with the selection logic tied to the model record.
MLL-III-514.5: 514.5 nm emission determines compatible optics, coatings and detectors for Optical instrumentation. The catalogued beam parameter (Near TEM00) helps predict how the source will focus and propagate through the instrument.
MLL-III-514.5: Laboratory measurement benefits from a stable, focusable source. 514.5 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (Near TEM00) informs waist size and propagation.

Technical FAQ
Cooled method: Conduction · 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.
Transverse mode: Near 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.
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.
