Stimulated emission depletion (STED) microscopy exploits nonlinear saturable optical transition of fluorescent molecules  allowed to overcome Abbe's diffraction-limit and provides diffraction-unlimited resolution in far-field optical microscopy. We elaborate the mechanism of STED and the conditions of depletion. The formula of STED microcopy resolution is deduced through effective point spread function (E-PSF). The STED system resolution is mainly dominated by the quality of the fluorescence depletion patterns in the focal plane. The depletion pattern is mainly affected by STED beam intensity  polarization  phase plate  primary aberrations  STED pulse shape  pulse duration and delay time. In this paper  we found related models and simulate the relationship between the depletion patterns and the parameters  and put forward effective approach to enhance the system resolution. 2010 SPIE.

In order to improve the measuring accuracy of the visible light phase-shifting point diffraction interferometer (PS/PDI) for the extreme ultraviolet lithography (EUVL) aspheric mirrors  the main measuring errors will be discussed in this paper. At first  the elementary configuration and measuring principle of the visible light phase-shifting point diffraction interferometer are introduced briefly  then the different errors which are possible to affect the measuring result are summed up  the errors include PZT phase-shifting error  detector nonlinearity error  detector quantization error  wavelength instability error and intensity instability error of the laser source  vibration error  air refractivity instability error and so on. Through detailed analysis and simulation  the magnitude of these errors can be obtained. By analysing the reasons which cause these errors and the relationship between these errors and interferometer configuration parameters  some methods are put forward to avoid or restrain these errors accordingly.

Off-axis illumination (OAI) technology is widely used to enhance resolution for deep ultraviolet lithography. The realizing methods of OAI include geometrical optics method and physical optics method. However  the former has the disadvantage of weak intensity distribution controlling ability  and the latter introduces simulation errors evidently when dealing with near field diffraction propagation. A diffractive optical element (DOE) designing method using plane wave angular spectrum theory is presented in this paper. Several kinds of OAI modes at near field away from DOE can be realized  and simulation errors and the size of illuminator are also reduced. According to studying the relationships of the sampling point distance of DOE  light beam propagation distance  and the structure of the beam shaping unit  a method of determining the designing parameters is discussed. Using this method  several illumination modes are realized  and simulation results show that all diffraction efficiencies reach up to 84%. The method of DOE manufacturing is analyzed at last  and it is proven to be feasible. 2010 SPIE.
