If lasers cross-over, do they "add up"

[Observeraren]

Hello,

If two lasers cross over, do tehy ionisate each other. If i have sensor in laser measuring ionisation going out etc can it see that laser 2 is crossing over it?

What do you mean by "ionisate each other"? "ionisate" is not a word.

If you mean the intensity: In general the intensities will add up. In special cases you can get interference, then it gets more complicated.
A better description of your setup would help.

Hello,

ok, what kind of intensities will add up? I want to have a sensor by the laser that can pick up the intensities. Does laser work in space?

Sure.

With "what kind of intensity" I am asking for the best way to measure the effect of a laser hitting another laser. I want to know with a sensor that if the another laser is crossing over the laser or not, in aerospace.
Thank you for your time. it is limited for all of us.

Can i have sensor in place A (from pic) measuring the laser beam and detect the crossover of the another laser.

EDIT: what kind of sensor.

Lasers don't hit each other; light waves pass through each other. You can, however, measure the "intensity" as power absorbed by a photodetector placed where they intersect. Is that what you are looking for?

Lasers don't "hit" each other. Two laser beams crossing each other will just pass through each other. There is no special effect that you could measure.
If you measure the intensity directly at the point where they cross, you'll measure the sum of the intensities of the individual laser beams.

The sensor at "a" won't be influenced by the vertical laser.
