…create a combined power of 2,400 W. The four
oscillator beams enter the LineBeam
will successively be mixed, expanded
and superimposed. Finally, the spatially combined line shaped beam of
1,300 mm length is projected onto
…reflected from a super-flat reference mirror. A second beamsplitter recombines
these reflected beams in a configuration called a Mach-Zehnder interferometer. The recombined
beam is then expanded and viewed using a CCD camera.

…order to either expand or reduce beam size.
Whatever the optical method chosen for
external beam attenuation, the most important
factor is that it introduces virtually no beam
distortion. To avoid or minimize beam
distortion, any attenuation optics in the beam
The beam divergence of a laser beam is a measure for how fast the beam expands as it propagates in space.
There are different quantitative definitions in the literature. According to the most common definition, the beam
divergence is the derivative of the beam radius with…
