Zeitliche Kohärenz

M2 = Beam quality (laser-dependent) k = Correction factor, depends on A and D (ideally 1.27; more typically between 1.5 and 2.0) A = Aperture of the scan system D = Beam diameter prior to focusing (typically 6 – 70 mm) λ = Wavelength (typically 193 nm – 10.6 μm) f = Focal length (typically 30 mm – 2,000 mm)

By transforming lasers into universal tools, scanning solutions help to add functionality and value to materials. SCANLAB's broad palette of scanning solutions fulfills demands for higher speed, more precision, greater efficiency or improved environmental compatibility.

Kohärenz einfach erklärt

Wie bereits in dem Kapitel "Phasenverschiebung / Gangunterschied" beschrieben, haben nur Wellen gleicher Geschwindigkeit und Frequenz eine konstante Phasenverschiebung.

Here you'll find explanations and definitions of key technical terms from the fields of optics, scanner technology, laser technology and laser processing.
