…beam waist is located at the flat high reflector. The long-radius output coupler acts as a weak lens to transfer the output-beam parameters. The values listed for beam divergence, beam waist diameter and beam waist location take into account the weak lens effect. The value for beam waist location…

…of either multiple waists
or no distinct waist found in the central 90% of the internal propagation axis. The multiple waist condition is a result of excessive laser
noise or other problems that can generate more than one internal
waist. The system looks for waist positions in the…

on the waist size that is set by the
optical system.
Far field divergence of a laser beam
can be described as the ratio of the
wavelength of the light to the beam
waist at a particular focus position.
Equation 4
In most applications, the waist of the laser…

…HyperRapid NX operating at 355 nm delivers a beam symmetry
of >90% over a depth of focus of more than 500 µm when focused to a beam waist of 15 µm.
This ensures optimal cut quality when cutting through OLED stacks of typical thickness (in the
200 - 400 µm range), regardless…
