Any laser that’s powerful enough to do that would leave an IR trail back to the source which would be visible with FLIR and most likely even with the naked eye

Any laser that’s powerful enough to do that would leave an IR trail back to the source which would be visible with FLIR and most likely even with the naked eye due to the atmospheric effects of heating up the air.

Not necessarily. If it's a femtosecond pulse laser, the instantaneous power is extremely high and creates a sufficiently intense field, but the time-average power is low enough that it wouldn't create much heat away from the focus. Source: worked in a femtosecond laser lab
