Abstract:
Methods, devices, and systems for amplifying laser pulses having different wavelengths in a drive laser assembly for an extreme ultraviolet (EUV) radiation generating device are provided. The drive laser assembly includes a radiation source configured to generate a first laser pulse having a first wavelength and a second laser pulse having a second wavelength, and an amplifier assembly having at least one optical amplifier for amplifying the first laser pulse and the second laser pulse. The amplifier assembly has at least one wavelength-selective optical element configured to attenuate the first laser pulse at the first wavelength more strongly than the second laser pulse at the second wavelength.

Claim (Index 17):
The method of  claim 15 , wherein the first laser pulse having the first wavelength is amplified during propagation through the amplifier system in a first propagation direction originating from a radiation source of the drive laser system, with a greater power-dependent amplification than in a second propagation direction opposite to the first propagation direction.
