Who said it is baffling? The problem is that if you cannot understand
the simplest of examples involving lossless, refractionless, laser
systems, you cannot possibly understand anything more complicated.
I haven't even read past your inability to understand that simple
example.

Um, yes. Can tell us why your example exhibits a reflection product
TEN TIMES BRIGHTER THAN THE SUN; when in your words it has canceled
completely? :-)

This question, like others, is likely to suffer the fate of you
whining on about "understanding." Go ahead anyway, it establishes you
as an academy of one - just don't chew the scenery.

It doesn't. All reflections are eliminated by wave cancellation.
That is a given boundary condition for the simple example.

You can argue that there's no such thing in reality as a
dimensionless point or a line of only one dimension or a
plane of only two dimensions. That doesn't keep such from
being taught as concepts in every plane geometry class.

What a larf. :-)

If you can't explain it, you simply re-write the math to suit the
outcome? This is neither demonstrable nor provable, unless, of course
you simply fudge the numbers until they agree with your result. Given
that every reader here has had the opposite experience as your
prediction, this is classic thumb on the scale work - quite shabby.

The purpose of the laser example is to make it as much like a
transmission line example as possible. A Bird wattmeter indicates
that all reflections are eliminated in the T-line example so
the laser example assumes that as a boundary condition. Your
insistance on rewriting the math to make it as different from a
T-line example as possible is simply a diversion away from the
original purpose.

Never met the class of Bird wattmeter that measures laser - and
neither have you. Get your thumb off the scale and put it where it
belongs.
