Even when it operates near the limits of technology available for the

as ChatGPT wrote, it's a novel way to prove/disprove E=mc² at optical
level.

Seems to me that the chatGPT estimate was extremely optimistic.
The maximum energy built up will be limited by the input energy
during each pass of the storage beam.  If the cavity were one
meter long, the time per pass would be 1/c.  How much energy
does a 5 W laser put out during that time? 1.67e-8 J.

If the end mirror absorbs 0.00001 of the energy per reflection,
the maximum energy in the cavity would reach only .00167 J.

You might get a 10x improvement of reflectivity and make the
cavity 10 m long, but you're still a long way from your dream,
methinks.  A scales to weigh a 10 meter pipe seems a bit
unwieldy to me.  You think maybe I made a mistake?  Check it
out yourself.
You are confusing cavity with something else.
I suggest you to read about the cavities used at Berlin University
during 1893-1900 (Wien, Planck - 2 Nobel Prize on the same matter), and
how to measure black body radiation.
I just thought of the exact opposite use of the small orifice: to allow
the laser beam to ENTER into the perfectly reflecting cavity, with
irregular inner coating, what allow that the laser beam be dispersed
within the small cavity, being confined there.
The laser beam can't escape, and is reflected everywhere inside. What
matter is the wavelength (550 nm - green) vs. the wide of irregularities
inside the cavity. Also, it has to be thermally stabilized, as well as
being in vacuum and protected from vibrations, electromagnetic
interference, etc.
LIGO array use lasers in the kilowatt range, mirrors with almost 100%
reflectivity, etc.
