Useally dust particles the laserbeam interact with and makes them visible and it was this interaction.
But even if these dustparticles are pretty big in regards something like molecules. I would reckon you still need a sensitivity able to sense this heat-energy of massless partcles interact with these dust particles. .
You can actually see these 5 to 7watt blue wavelength beams and the energy/heat messing up the dust-particles.. .
and was wondering if third-party interactions like , dust, fog, foam etc could help on the matter.
But need to try it out, but a Seek pro is certainly not the most sensitive thermal cam on the market
when it comes to small heat differences and like fx 5w 465nm laser beam interacting with dust particles in air..
but likely need to try and error.. just a noob on thermal sensors and the risk of hurting these and usually optic-cam-sensors and high powered-laser beams are not friends..
These intense beams and this bright intense light loves tumbling the optic cam-sensors at angled recordings.. how it is with thermal-cams sensors. I don't know if this intense light (offcourse not direct) can hurt these thermal-sensors.

All Native with just the Seek pro..
First two a new water heater from phllips..
plus an old pavillion laptop and a metal PSU.
