Question

When a high-power laser is used in the Earth's
atmosphere the electric field associated with the laser
beam can ionize the air, turning it into a conducting
Plasma that reflects the laser light. In dry air at
0°C and 1 atm, electric breakdown occurs for
fields with amplitudes above about 3:00 Mv/m
a) At this maximum Intensity, what Power can be
delivered in a cylindrical beam diameter
4
3.03mm?
Note Answer must be in W.

Optical tweezers use light from a laser to move single atoms and molecules around. Suppose the intensity of light from the tweezers is 1000 W/m², the same as the intensity of sunlight at the surface of the Earth. (a) What is the pressure on an atom if light from the tweezers is totally absorbed? Pa -27 -29 (b) If this pressure were exerted on a tritium atom, what would be its acceleration? (The mass of a tritium atom is 5.01 x 10- kg. Assume the cross-sectional area of the laser beam is 6.65 x 10- m/s² m².)
