Exclusive Authorization - EUV / Soft X-ray Hartmann Wavefront Sensor

The Shack-Hartmann (or sometimes Hartmann-Shack) wavefront sensor is the most common type of wavefront sensor, named after Johannes Franz Hartmann and Roland Shack.

Extreme ultraviolet (EUV) lithography has been widely used in semiconductor manufacturing to produce advanced microelectronic chips. EUV wavefront sensors can be used to monitor and control the wavefront characteristics of EUV light sources, ensuring high-precision patterning.

In astronomy, EUV radiation is an important tool for studying phenomena such as stars, planetary atmospheres, and cosmic rays. EUV wavefront sensors can help astronomers measure and analyze the wavefront characteristics of EUV radiation to better understand various phenomena in the universe.

In plasma physics experiments, EUV radiation is often used to generate and study high-temperature plasmas. EUV wavefront sensors can be used to measure wavefront aberrations within plasmas, helping to investigate the properties and behavior of plasmas.

EUV laser research is also an important field that requires wavefront sensing measurements of EUV light sources, which is crucial for developing EUV laser technology and for using EUV lasers in scientific and industrial applications.

In summary, EUV wavefront sensors play an important role in the research and application of EUV radiation, helping to measure and control the wavefront characteristics of EUV light sources, thereby improving the precision and efficiency of various applications.

The Shack-Hartmann (or sometimes Hartmann-Shack) wavefront sensor is the most common type of wavefront sensor, named after Johannes Franz Hartmann and Roland Shack. It is used for laser beam characterization, enabling real-time prediction of the propagation behavior of laser radiation and M2 measurement of coherent light sources: using the Fresnel-Kirchhoff integral method, the beam profile at any position along the laser beam path (particularly the focal plane) can be calculated by simultaneously recording intensity and phase distribution data. The propagated profile agrees very well with directly measured camera data, which is especially important when dealing with very small focal spots and fluctuating light sources.

The applications of the Hartmann-Shack extreme ultraviolet (EUV) wavefront sensor in various fields mainly focus on wavefront correction, optical system performance optimization, and wavefront aberration measurement, to ensure precise wavefront control and high-quality performance of optical systems.
