Actual Spot Size at Focus
Similarly, M2 can be applied to the formula used to
calculate the size of a focused Gaussian beam. The
equation for calculating the spot size of a perfect
Gaussian beam focused by an aberration free lens is

Beam quality
Beam mode quality directly affects focused spot size, which in turn determines
system optical efficiency. This is because
a confocal microscope works by focusing
the laser to a small spot or spots in the
sample plane and imaging fluorescence
from this spot

…applications). The other significant advantage of shorter wavelength is that it can be focused to a smaller spot size than a longer wavelength. The CO laser output can be focused to a spot 2 times smaller than that of a CO 2 laser. This enables the production of smaller holes and features, and…

Focusing Units

Focusing Units

Focusing Units With a focusing unit the parallel beam from the collimating unit is focused down to the workpiece. The size of the focused spot and the depth of focus are given by the ombination of collimating optics, focusing optics and beam quality. The Optoskand focusing units come either with a…

…films, wooden tongues, acrylic blocks, fluorescing plates or cards, etc. These simple methods of laser
beam evaluation have clear disadvantages: Poor resolution; the spot size is highly dependent on exposure time; since
the results are not quantitative, they are subject to subjective…

…upgrade. And if you’re already using AVIA lasers, upgrade is very simple because AVIA NX is backwards compatible delivers exactly the same unmatched beam parameters as earlier models and uses common software commands. The end result is lower cost of integration, lower cost of ownership and greater…

Changing to visible light sources would overcome the limitation, since they would yield smaller spot sizes for the same M2 value. Visible DPSS lasers obviously provide a high-quality mode, but their current size and cost…

…from 10 kHz to 30 kHz. A beam parameter product of typical 20 mm x mrad (for a 400 μm, round core output fiber) enables this power to be effectively concentrated into small focused spot sizes. The unique combination high average power, high pulse energy and superior beam quality makes the HighLight…
