2.A Fast Algorithm for the Propagation of Partially Coherent Beams througha Multiple Hard-Edged Apertured ABCD Optical System
3.Approximate close-form expression for Gaussian beams passingthrough an ABCD optical system with hard-edge aperture
4.The window function of circular hard-edge apertures is simulated and optimized by the Laguerre-Gauss truncated series, and applied to study the diffraction of Gaussian beams and 0-order Bessel-Gaussian beams by the hard-edge aperture.
5.The design had friend human-computer interfaces to monitor the field situation, realized the high precision temperature control with the PID-Fuzzy control method, realized the high precision control for motor combining PLC with closed-loop control and tension-monitor on-line of variable frequency drives, avoid the hard border and overlapping yarn by four grades stroke modification and changing winding angle incessantly.
7.The results reveal that the composition with 60% in mole P2O5 has the highest refractive indices(1.522 0),lowest glass transition temperature(352.4 ℃),good relative chemical durability 0.52 mg/(cm2.d)and suitable thermal expansion coefficients(128.427×10-7/℃). This material is better candidate as the edge-cladding glass for neodymium phosphate laser glass.
9.The laser-induce damage threshold (LIDT) of Ta 2O 5/SiO 2 two-cavity narrow-band interference filters with different central wavelength was investigated with a Nd∶YAG laser at 1064 nm under single-pulse mode, and the absorption measurement of such coatings was also performed by surface thermal lensing (STL) technique.
10.While whisking, slowly pour in hot milk. Continue cooking, whisking constantly, until the mixture bubbles and becomes thick.
