The very small aperture laser(VSAL) is an important light source used in the near-field optical storage system. The near-field property of VSAL′s output light is studied. The optical characteristics and the intensity distribution in the near-field of the output region,that is, micro-aperture metallic film, of the VSAL have been numerically simulated by using two-dimensional nonlinear finite difference time domain(2D-NL-FDTD) method and the Fox-Li method with angle spectrum. Through analyzing the results from the viewpoint of the optics, the possible application in the near-field optical recording have been discussed, and some curves indicating the near-field optical charactersistics of the output light have been presented. It is found that because of the localized surface plasmon ehnancement for the TM mode, the output of TM mode is about ten times stronger than the one of TE mode and more suitable for being used in the near-field optical storage system.
