Very interesting
I can see that as a handy tool for eaves dropping and spying.

I seem to remember...
...that shining a laser on the window and recording the vibrations was used as a method of eavesdropping. Presumably using a high speed camera since Q has the budget for it!
Interesting link

You’d use an interferometer setup to generate an analogue signal
But yes. Lasers can be used to record sound at a distance, as long as you have a sufficiently flexible surface to bounce the laser off. Glass works.

Given someone worked out how to see* through bushes at a distance I wouldn't be surprised if they haven't worked out how to work with multiple lasers to combine and recreate audio from poorer sources
*used multiple sources then reconstituted what was on the other side

Yes, that was on
Tomorrows World back in the 80s! And I'm sure tech has moved on since then... the quality from this method certainly sounds improved.

I’m sure I read about it in an old Larry Niven book too.
