The area is usually the spot size of the light device.

The focused spot size must be large enough to span across several pixels.

However, the focal spot size is dependent on the intensity of the laser being used for depletion.

As a result, this spot size can be tuned, changing the size and imaging speed.

Recent applications have altered Lee's design in order to decrease spot size while simultaneously increasing the intensity of this laser.

It was the smallest spot size and shortest pulse length ever achieved at that intensity.

And from the changes in the spot size you can get the divergence angle, and therefore the range.

'I'll change the spot size of the beam to get a little more energy.'

The actual sampled resolution will depend on the spot size and intensity distribution.

Both pump and probe have a spot size on the order of 10-50 μm.
