Wich lasers produce a beam with a linear polarization?
Wich lasers send out unpolarized radiation?
What means a „beam with high beam-quality“(hohe Strahlqualität)“in laser materials processing?.
A beam, that can be focussed to a minimized focus diameter.
What are the three different and common factors/properties, with which the beam-quality (focussability) of a lase-beam can be expressed?
- BPP beam-parameter-product
- M2
- K
Best possible beam-quality or focussability (= „ Gaussian-Profile“of the brightness- or intensity distribution) is then expressed when the number M2 or K = ?
Which Laser possesses by far the lowest (worst) focussability of the 3 lasers?
Diode-laser
Which Laser possesses the best focussability?
YAG-laser
