High Power Beam Analysis
The advantages of fiber lasers are their high power, mechanical stability and good beam quality; however beam quality and beam profile has to be periodically checked. In general, there are many difficulties in checking beam quality especially at the focal point, where densities will exceed 50KWatt per square cm. On one hand those energies are capable of melting and destroying most known materials, while on the other hand measuring a focused profile is the most significant measurement.
