It is a great addition to the discussion. With some more technical and practical information. Also look in the comments for people with experience with satellites.
Based on that video, I likely have overestimated the energy necessary for a fire. But also more details need to be figured out. It is a good thing that technical people are looking how it could work or not work exactly.
It was very windy, and looked cloudy. And any water in the air absorbs infra-red. Far more than CO2 and Ozone.
Lasers also have a problem with energy and distance. (1) How much energy can the laser output? 500watt for 1 minute? (Energy=500x60= 30 kJoule). Or 5Gwatt for 1 nanosecond (Energy= 5 Joule).
(2) Do you know that a laser beam diverges and disperses? How much well can the laser focus its output-energy to an area? From 200 kms high it is around 1 square mile? Or 1 square meter?
One joule can increase the temperature of one liter of water to 1 degrees in Celsius. So 5 joules is nothing.
And 30 kJoule over 60 minutes gives the target time to cool down. Compare that to the sun with about 1000 watt per square meter, 60 kJoule/minute.
And based on these numbers, it looks like these lasers are pretty much harmless. I think they may want use it for other satellites? The known military weapons are all for close range, like a few kilometers.
Even the Boeing YAL-1 (with a huge and very powerful chemical laser) was only short range capable. See-> https://www.youtube.com/watch?v=r-dEXaSJWME Modern lasers are electrically powered are smaller but have far less power output. There were also theoretical plans for nuclear explosion powered space lasers, but that required a nuclear explosion. If I am missing something, some new technology, please let me know.
So personally, I think it was just simple arson, strengthened by the strong wind. The wind also kept the fires low to the ground. People like to blame other countries or top secret tech, but just like in Greece pyromaniacs and eco-terrorists can do the trick.
Well, the data analyst has open software to check the numbers he has come up with for the tons of equipment shipped to the satellite and 70 x gigawatt capacity or some such and is capable of sending up 48,500 kgs when around 32,000 of weight in capacitors would e needed.
I will leave it to your field of expertise. Steve Favis has a contact page on his website.

Thanks for reply. It would be interesting to have an open discussion about this with some different opinions.
I do think that it is useful for war in space, to shoot other satellites. Within short distances. In space vacuum there is no dispersion due to air. So a laser can reach larger distances. But not extreme.
A 70 x gigawatt capacity.. how long does it last? A powerful pulse is usually below 1 nano-second, resulting in only 70 joule. It is strong only by targeting a very small area. This 70 joule on a 2x2 mm area becomes 17,000,000 joule/meter. But the electrical laser can only convert 1% of the electrical power into light. So it becomes 170,000 joule/meter.
Still enough to melt a very small hole. Good enough to disable a satellite, I would think.
Here is a recent video about "direct energy weapons", but it uses biased information from military industry. It is often like an advertisement. -> https://www.youtube.com/watch?v=JBsQ6fyr1WE
Tech ingredients made a video about this. Could satellite lasers really do this?..

This is no theory. It is a conspiracy however. To depopulate humanity.
That is not new. Locnheed
