They are your details and you can't do the math. You instead beg it
doesn't make sense to? Certainly not from the perspective of your
theories. ;-)

It seems you have forgotten the purpose of the laser example.
It was supposed to be as much like a transmission line example
as is possible. Refraction is irrelevant in a transmission line
so there's no logical reason to introduce refraction into the
simple laser example. A laser was chosen to make the example
single frequency and coherent like an RF source. Occam's Razor
is used to trim off all irrelevant stuff.
