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 lead the laser beam transmit in the atmosphere convergently
an experiment of laser focus at the distance of 450m and 300m has been operated in the outdoor place. The actual manipulations are as follows: Firstly
the laser was collimated by a beam expander
then the near-parallel laser beam was transmitted with a Galileo telescope system
and the distance between the concave lens and the convex lens can be tuned through a precise displacement platform
so the focus of the system changed due to the tiny displacement of the concave lens. Secondly
the average power of the laser spot can be measured using power meter
the power is 47.67mW and the standard deviation is 0.67mW while the focal length is 450m. Thirdly
the energy distribution was found through the laser beam analyzer. The spot images were saved using the beam analyzer
then the saved image can be processed with Matlab software afterwards. The function named EDGE and Sobel operator was used in the pre-processing of the saved image
then method of median filter was used in the course of image de-noising and 53H filter was adopted in the signal analysis. The diameter of laser spot was obtained by the method above
the diameter is 5.56mm and the standard deviation is 0.24mm. The spot center excursion is 0.56mm
it is 10.43% of the total diameter of the laser spot. At last
the key factors of the energy dissipation in the focusing system can be summarized as follows: restriction of the diffraction limit
attenuation in the atmosphere
geometrical aberration of optical system
and the diffraction limit and the geometrical aberration are significant in the three factors above
so we can reduce the impact of the both factors during the design of optical system. The reliable referenced data of the system design can be acquired through the primary experiment research. 2010 SPIE.
