Mirror assembly for guiding a laser beam in a laser system and laser guidance method for a laser beam

摘要

The arrangement has end mirrors (1, 2) forming a resonator with an optical resonator axis (OA). The resonator is formed as Herriott-cell, where laser beam is guided as input laser beam (ES) into the resonator and is guided as output laser beam (AS) from the resonator after multiple reflections at the end mirrors. The sequence of reflections defines a rotational direction between the end mirrors. The resonator is formed such that the rotational direction is reversed in a reversal point and the laser beam traverses the resonator partially with the rotational direction to define a beam path. Independent claims are also included for the following: (1) a laser system comprising Neodymium-doped yttrium orthovanadate laser (2) a method for guiding laser beam in a laser system.
