Technical FAQ
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.
M²: <1.2 · 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.
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.
