A CO2 laser produces a cylindrical beam of light with a diameter of 0.850 cm. The energy is pulsed, lasting for 2.00 ns, and each burst contains an energy of 200 mJ.
What is the length L of each pulse of laser light?
What is the average energy per unit volume u(avg) for each pulse?
When a powerful laser is employed in the Earth's atmosphere, the accompanying electric field may ionize the air, transforming it into a plasma that reflects the laser light. Electric breakdown occurs in dry air at 0°C and 1 atm when field amplitudes above around 3:00 Mv/m a). At this maximum intensity, how much Power can a cylindrical beam with a diameter of 4.03 mm deliver? Note Answer must be in W.
