Analysis of the Propagation Characteristics of Linear Chirped Laser Pulses with Gaussian Temporal and Gaussian Spatial Structure
The phase characteristics of the linear chirped laser pulse with Gaussian temporal and Gaussian spatial structure is studied by using the stable phase point method while propagating in vacuum. And under the second order approximation, its spatial and temporal characteristics are discussed. The conclustion from the two methods is that the Gaussian laser pulse will degenerate into a spherical wave or into a planar wave under the paraxial approximation in the very far distant while traveling in vacuum.
