Abstract
A laser system includes a multipass amplifier for amplifying laser light and providing an amplified output beam, and a control unit. The multipass amplifier includes a laser-active medium. The control unit is configured to keep a thermal load on the laser-active medium substantially constant over a range of a laser output power of the output beam. The thermal load is determined by at least two different power sources.
Claims19
A laser system comprising:
- a multipass amplifier for amplifying laser light and providing an amplified output beam, and
- a control unit,
- wherein the multipass amplifier comprises a laser-active medium, the control unit is configured to keep a thermal load on the laser-active medium substantially constant over a range of a laser output power of the output beam, wherein the thermal load is determined by at least two different power sources.
A method for amplifying a seed laser beam in a multipass amplifier comprising a laser-active medium, the method comprising:
- amplifying the seed laser beam using the multipass amplifier to provide an amplified output beam, and
- keeping a thermal load on the laser-active medium substantially constant over a range of a laser output power, wherein the thermal load is determined by at least two different power sources, and wherein the thermal load on the laser-active medium is kept constant in a range of ±10%.
