Lasers & Optoelectronics Lecture 8: Gaussian Beams (Cornell ECE4300 Fall 2016)

In this class, the Gaussian laser beam equation is discussed in detail with definition of the key equation parameters.
Cornell ECE4300 taught in Fall 2016 by Profs. Debdeep Jena and Clif Pollock. (Website: djena.engineering.cornell.edu...)

Hello! @

[@nivesh3555]

I also get the second derivative wrt z in the 3rd equation(equation for psi). Could anyone explain how the second derivative wrt z was cancelled from equations 2 to 3?

Is there a 2nd class of this subject? I still didn't get how to sort out the distance from the tip of the light source to the beam waist i.e. where the beam waist (z=0) located in space. Can anybody help me?
