Abstract

Based on the second order moment of the accurate light intensity at the transverse plane , the Transmissior characteristics of nonparaxial Gaussian beam have been investigated .The beam width follows a simple hyperbolic propagation law .The numerical results also show that the propagation factor M2 of nonparaxial Gaussian beam is a function of the initial Gaussian half width w0 , and M2 factor can be smaller than unity as w0 being smaller than 0.123 times of the wavelength .
- light beam,
- nonparaxial Gaussian beam,
- transmission characteristic,
- initially Gaussian width
