Main Question or Discussion Point
Hi!.
I´m modeling a gaussiam beam. I found that considering the electric field distribution of Gaussian laser pulses along the axis of propagation, we can write the intensity as:
Where [itex]y = I_l[/itex]
R is the power is the power reflection coefficient
[itex]y = w_0[/itex] is the beam waist radius at [itex]y = z=0[/itex]
[itex]t_l[/itex] is the laser pulse duration
But, I don´t now what represents [itex]r[/itex] in the formula. I find that r is the distance from the center axis of the beam, but i don´t understand this explanation.
Thank you very much.
