摘要:
Fields of a focused supercontinuum laser with different center wavelength are studied near the focus in this paper. Effects of the spectrum property on the intensity distributions of the laser are analyzed in detail by numerical calculations. The results indicate that the maximum intensity is shifted toward the lens as the center wavelength decreases and it is deviated from the lens as the center wavelength shift to long wavelength. Influence of the center wavelength on the shift of the maximum intensity is smaller in the laser with broader ban...
