All laser experiments beyond the immediate land-water horizon (about 3 - 5 miles) are invalid because of:
a) laser beam divergence / expansion
b) atmospheric refraction
c) atmospheric interference from all kinds of distortions
Any test beyond horizon 2 (as shown below) is subject to atmospheric distortions of many kinds. It's not possible to subtract those effects out:
temperature inversion
atmospheric ducting
atmospheric looming, sinking, towering & stooping
inferior mirage, superior mirage, and Fata Morgana
standard atmospheric refraction
There is no need for long distance laser experiments. Anyone can prove flatness or curvature within the first 5-km.
Observer height:
1-meter laser height to 3.6-km limit
2-meter laser height to 5.1-km limit
5-meter laser height to 8-km limit
Due to a normal temperature gradient found in the atmosphere, light rays are bent 1/5 or 1/6 the Earth’s curvature.
With a temperature inversion (increase or decrease) of 6.3o F per 100-feet, the curvature of a light ray is of the same order as the curvature of the Earth.

So what is happening when those folks show you a laser beam still visible at 6, 12, 14 kilometers away? "spot the laser" does not mean that the Earth is flat, because of atmospheric refraction, laser pointing downward at the distant horizon, and laser beam divergence.
Here is a demonstration...

Bedford Level Experiment...

with a laser on the boat...
-
-
Summary:
The laser on the boat 6-miles away is visible on the shore because of atmospheric refraction & laser beam divergence - ONLY.
6-miles away is over the curve and ordinarily not visible.
This is why those laser tests of "I see the beam" are misleading and do not prove flatness in any way.

Physical Meteorology, by John Johnson, Tufts College, 1954
Refraction effects arise because the atmosphere is neither a constant-density medium nor free space. Electromagnetic waves are propagated with speeds that are a function of the density and to a large extent the internal electrical structure of the molecules of gas in the atmpshere. The ratio of the speed of propagation of the radiation in free space to the speed of the radiation in a medium, in this case the atmosphere, is called the index of refraction.
m = c / v
Mirages arise from terrestrial refraction.

It's easy to prove flatness or curvature within 5-km, by passing the very center of a laser beam thru a small 1-cm hole in fixed measuring rods - "eye of the needle experiment"...
