Lasers can be used to drill or cut material. One such laser generates a series of high-power pulses of light. Each pulse contains 550 mJ of energy and lasts 10 ns.

A lens focuses the light on a 10-micro-meter -diameter circle. What is the light intensity during the pulse?

Lasers can be used to drill or cut material. One such lasergenerates a series of high-intensity pulses rather than acontinuous beam of light. Each pulse contains 460 mJ of energy andlasts 10 ns. The laser fires 10 such pulses per second.

Part A -
What is the peak power of the laser light? The peak power is thepower output during one of the 10 ns pulses.
Express your answer using two significant figures.
Ppeak = __________W

Part B -
What is the average power output of the laser? The average power isthe total energy delivered per second.
Express your answer using two significant figures.
Pavg = _________W

Part C -
A lens focuses the laser beam to a 10 μm diameter circle on thetarget. During a pulse, what is the light intensity on thetarget?
Express your answer using two significant figures.
Ilaser = _________W/m2

Part D -
The intensity of sunlight at the surface of the earth at midday isabout 1100 W/m2 . What is the ratio of the laserintensity on the target to the intensity of the midday sun?
Express your answer using two significant figures.
Ilaser/Isun= _________

LASIK eye surgery uses pulses of laser light to shave off tissue from the cornea, reshaping it. A typical LASIK laser emits a 1.0 mm diameter laser beam with a wavelength of 193 nm. Each laser pulse lasts 15 ns and contains 1.0 mJ of light energy. 

(a) What is the power of one laser pulse?

(b) During the very brief time of the pulse, what is the intensity of the light wave?

In LASIK surgery, a laser is used to reshape the cornea of the eye to improve vision. The laser produces extremely short pulses of light, each containing 1.0 mJ of energy. in each pulse, there are 9.7×1014 photons.

(a) What is the wavelength of the laser?

(b) Each pulse lasts only 20 ns. What is the average power delivered to the eye during a pulse?
