The definition of beamwidth is significant for the quality of laser beam.
在激光光束质量问题中,光束束宽的定义至关重要。

When the initial power equals the critical power a stabile spatial soliton is obtained and generally the beamwidth takes periodical contraction or diffraction.
当初始功率等于临界功率时,可以得到一个稳定的空间孤子,而一般情形下,束宽则作周期的压缩或展宽变化。

It is shown that the positions of phase saddles and vortices depend on the off-axis parameter, beamwidth, phase and relative amplitude of beams.
