Abstract:
The present disclosure provides an excimer laser system. A master oscillator chamber may generate laser pulses with a narrowed line width and a small energy by means of a line width narrowing module, as a seed light. The seed light is refracted by a master oscillator wavefront engineering box and then incident into a power amplifier chamber through a beam splitting system. The beam splitting system, a first high reflectance mirror, a second high reflectance mirror and a third high reflectance mirror may constitute a quadrilateral annular optical path, The power amplifier chamber may have a first pair of Brewster windows and a second pair of Brewster windows, wherein the first pair of Brewster windows is located in a first optical path of the annular optical path along with a discharging electrode of the power amplifier chamber, and the second pair of Brewster windows is located in a second optical path of annular optical path which is parallel to a first amplification optical path. The present disclosure reduces the length of a ring cavity of an excimer laser system with a ring cavity structure, increasing the amplification times and achieving a deeper gain saturation amplification than a traditional structure, thereby improving the output characteristic of the excimer laser system.

Claim (Index 2):
The excimer laser system of  claim 1 , wherein the power amplifier chamber (PA) has two parallel discharging electrodes, and the first optical path and the second optical path in the annular optical path pass through the two discharging electrodes, respectively.
