I've looked at various types of lasers and their specs and cant seem to figure out what affects the 'maximum distance' ?

Below is a kind of a 'tale' of what ive done trying to figure it all out.. and will probably make most people laugh at my lack of knowledge and or education, so if you can answer the question above no need to read the following thanks.

A laser ive seen is the 1W S3 Krypton which has a massive max distance of around 136kms. I then compared this to the 300mw version which has a max distance of around 41km. So I figured it must be proportional or atleast related to its power. Then I compared it to another model, the S3 Artic (also 1W).

Though this is where my confusion begins, it has an equal max power than the Krypton yet only a max range of 6.8kms.

So then I thought, the wavelength must also have an influence on the max distance. So looked at other lasers, in particular the E3 Series. First I noticed the wavelengths (405 nm, 532 nm, 650 nm) = beam distance (745 meters 16474 meters 8616 meters) so as far as I could tell increasing or decreasing the wavelength didnt equate to a larger or smaller distance.

Then second, I noticed the 300mW 532 nw model had (obviously) the same wavelength and max power as the S3 Krypton. Yet the Kryptons max distance was 41kms and the e3 was 16.4kms ?

So as far as I could tell theres something other than the wavelength and max power that contribute to the max distance.. Ive looked at the other tech specs of these devices and cant figure out what makes one 1W laser shine over twice the distance of another seemingly identical one ?
