摘要： 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.

摘要： A scanning type laser induced spectrum surface range analysis and detection system includes a laser emitting head connected to an external laser inducing light source, which generates lasers emitted through the laser emitting head, so as to generate laser induced plasma. A focusing optical device converges induction excited laser beams emitted by the laser emitting head onto a surface of a tested sample. Then, a reflector collects wide spectral range induced plasma scattered light signals of the tested sample and converges the signals into a light collecting device. The light collecting device converges induced plasma scattered light into an optical fiber and transmits the induced plasma scattered light to an external spectrograph; and the external spectrograph divides a spectrum formed by the plasma to obtain spectral strength data of different wavelengths.
