Laser system, method for creating at least one shaped and amplified laser beam using a laser system, and optical system

Abstract

The invention relates to a laser system having a laser radiation source, an optical element and a laser-active amplification device with a first side facing a shaped laser beam and an opposite second side. A beam shaping device is disposed between the laser radiation source and the one optical element and serves to create a laser beam that is shaped with regard to an intensity distribution and/or a phase of the laser beam. The optical element steers the shaped laser beam to the amplification device. The amplification device amplifies the shaped laser beam by means of a pump beam and emits said laser beam as amplified shaped laser beam. The shaped and/or amplified laser beam is diagnosed in order to control and/or regulate the beam shaping device by means of a feedback loop. The invention also relates to an optical system and a method for creating the above type of laser beam.
