Determine power can be delivered in a cylindrical beam

Reference no: EM13486570

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) What laser beam intensity will produce such a field?

(b) At this maximum intensity, what power can be delivered in a cylindrical beam of diameter 3.98 mm?
