Abstract
A method and system for amplifying seed laser radiation which is irradiated along an irradiation direction into a lasing amplification medium has a transverse seed laser intensity profile that is transformed into a plateaued input intensity profile by a transformer element on the irradiation side.
Claims16
A method, comprising:
- amplifying seed laser radiation that is radiated into a laser-active amplifier medium along an irradiation direction,
- wherein the seed laser radiation has a transverse seed laser intensity profile that is transformed into a plateau-shaped input intensity profile by a transformer element on the irradiation side,
- wherein the input intensity profile maintains the shape of the seed laser intensity profile along a transverse direction of the seed laser radiation, and wherein the transverse direction is along a fast axis.
An amplifier for amplifying seed laser radiation that is radiated into a laser-active amplifier medium along an irradiation direction, the amplifier comprising:
- one or more elements comprising the laser-active amplifier medium,
- wherein the seed laser radiation has a transverse seed laser intensity profile that is transformed into a plateau-shaped input intensity profile by a transformer element on the irradiation side,
- wherein the input intensity profile maintains the shape of the seed laser intensity profile along a transverse direction of the seed laser radiation, and wherein the transverse direction is along a fast axis.
A method comprising:
- amplifying seed laser radiation that is radiated into a laser-active amplifier medium along an irradiation direction,
- wherein the seed laser radiation has a transverse seed laser intensity profile that is transformed into a plateau-shaped input intensity profile by a transformer element on the irradiation side,
- wherein an inverse transformer element inverse-transforms the output intensity profile of the amplified seed laser radiation in the manner of a transformer element into an intensity profile that is similar to the seed laser intensity profile.
