Abstract
A laser arrangement has a first optical element, provided and established to convert a first laser beam having a first frequency into a second laser beam having a second frequency, wherein the second frequency is higher than the first frequency, and has a second optical element, which is transmitting for the first laser beam and reflecting for the second laser beam, and which is provided and established to reflect the second laser beam in a direction of reflection. Both the first optical element and the second optical element are movably mounted in such a way that they can be moved relative to a direction of light propagation of the second laser beam.

A laser arrangement having
- a first optical element, provided and established to convert a first laser beam having a first frequency into a second laser beam having a second frequency, wherein the second frequency is higher than the first frequency,
- a second optical element, which is transmitting for the first laser beam and reflecting for the second laser beam and which is provided and established to reflect the second laser beam in a direction of reflection,
- wherein both the first optical element and also the second optical element are movably mounted in such a way that they can be moved relative to a direction of light propagation of the second laser beam.
A method for enhancing the life span of optical elements in a laser arrangement, comprising the following steps:
- channeling a first laser beam having a first frequency onto a first optical element,
- converting the first laser beam by means of the first optical element into a second laser beam having a second frequency, wherein the second frequency is higher than the first frequency,
- channeling the second laser beam onto a second optical element, which is transmitting for the first laser beam and reflecting for the second laser beam,
- reflecting the second laser beam by means of the second optical element along a direction of reflection,
- moving the first optical element and the second optical element relative to a direction of light propagation of the second laser beam after a first time duration.
