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 11):
The drive laser system of  claim 9 , wherein the at least one optical amplifier is configured and controlled to:\n operate in a saturation state when the first laser pulse propagates in the first propagation direction through the at least one optical amplifier with a laser power greater than a power threshold value, and operate in an unsaturation state when a reflected first laser pulse propagates in the second propagation direction through the at least one optical amplifier with a reflected laser power below the power threshold value.
