It is a key point of CO2 laser beam monitoring in the CO 2 laser processing system to achieve alignment between CO2 laser and PL (pointing and launching) system. By monitoring the angle offset of CO2 laser beam
the compensation can be gotten witch is given to fast-steering mirror to rectify the direction of laser beam. But the normal photoelectric detector can not get the laser signal because of CO2 laser's high energy and long wavelength. Its wavelength is 10.6m and its power can reach kW level. Consequently
it is difficult to detect the high-energy 10.6m laser beam directly. So
we monitored the output mirror of laser resonator superseded the laser beam
indirectly. The laser beam monitoring system could be designed based on CCD laser auto-collimation angular measurement principle and image processing method. In this paper
application of CCD laser auto-collimation angular measurement principle and image processing method for CO2 laser beam monitoring system is introduced particularly
After design
fabrication and alignment
the monitoring system can be used for experimental study that including angular measurement accuracy and angle offset measurement of CO2 laser beam. Angle offset range and angle variation rule of CO2 laser beam is also can be acquired for further research.

An experimental EUVL system has been developed to investigate EUV imaging system design
component fabrication
assembly technique and experimental process. The system includes a laser produced plasma (LPP) source
an ellipsoidal condenser
a transmission mask
a reduced projection optics
and vacuum system. We designed a 10:1 reduction projection optics using Schwarzschild system with spherical mirrors to achieve 0.1m resolution. The Schwarzschild optics coated with Mo/Si multilayers was assembled with wavefront error (WFE) of 0.014 waves RMS at 632.8nm wavelength under computer-aided alignment method. Using this system a fine pattern of less than 0.25m covering a 0.1mm diameter image field of view was clearly replicated on resist-coated wafer.

Comparing with the writing method of plane pattern
spherical pattern' has some remarkable different on several points. Firstly
it is difficult to spin-coated a uniform photoresist film on a spherical substrate
especially the ratio of spherical radius to caliber is smaller
and the spin-coated way must match the ratio of spherical radius to caliber. Secondly
if the sphere couldn't be regarded as a plane
a so-called concentric optical scan movement way must be applied for the generation of spherical pattern
because the reflex of substrate will affect the quantity of illumination. Commonly
an alignment technique is indispensable with pattern generation of spherical surface by the concentric optical scan in order to ensure the orthogonal intersection of focusing laser beam and writing surface. Thirdly
a uniform velocity control must be considered for the laser direct writing method on a spherical substrate. Otherwise
the exposure time of photoresist will be different
and the line widths of pattern will be also different at different areas. Fourthly
commonly
because the errors of concentric machine and substrate surface shape are bigger
so focusing servo-control technique is also needful for writing a pattern on a spherical substrate. Focusing servo-control may keep the focal spot on the spherical surface by a focus detection and control system in the course of writing pattern. Using these techniques
we fabricated a line width of 7m and a period of 600m isometric mesh on the concave of a spherical substrate.
