College Physics
Lasers are used extensively in eye surgery to remove unwanted material from the eye or reshape the eye lens. These lasers use pulses of very intense radiation to literally blast away material. The pulses are generally 9.141 ns long and carry an energy of 1.91 mJ each. What is the power during one these pulses? 3 attempt(s) made (maximum allowed for credit = 5) [after that multiply credit by 0.5up to 10attempts] 20894 NO If this energy is delivered to a spot on the eye that is 1.0 mm in diameter, what is the intensity during a pulse? 0 attempt(s) made (maximum allowed for credit = 5)[after that multiply credit by 0.5up to 10attempts] If the radiation has a wavelength of 350 nm, what is the electric field amplitude during a pulse? 0 attempt(s) made (maximum allowed for credit = 5) [after that multiply credit by 0.5up to 10attempts]Explanation / Answer
