• 1. hyperbolic secant beam: 双曲正割光束
• 2. hyperbolic secant shaped optical beam: 双曲正割型光束
• 3. hyperbolic secant pulsed beam: 双曲正割脉冲光束

• 1.By starting from the paraxial wave equation, the analytical expression of the ultrashort Hyperbolic Secant pulsed beam are deduced.
  从傍轴波动方程出发，给出了超短双曲正割脉冲光束的解析解。
