Chapter 33: Q9P (page 1001)

Some neodymium鈥揼lass lasers can provide100TWof power in1.0nspulses at a wavelength of0.26渭m. How much energy is contained in a single pulse?

Short Answer

Expert verified

Energy contained in a single pulse is 1.0脳105J.

Step by step solution

01

Determine the given quantities

Laser power is:

P=100TW=100脳1012W

Pulse time is:

t=1.0ns=1.0脳10-9s

02

Determine the concepts of energy and power

The energy depends on power and time.

E=Pt

03

Determine the energy contained in a single pulse

The energy and power are related as

E=Pt

Substitute the values and solve as:

E=100脳1012脳1.0脳10-9=1.0脳105J

Energy contained in a single pulse is 1.0脳105J.

In Fig. 33-55, a 2.00鈥尘long vertical pole extends from the bottom of a swimming pool to a point 50.0cmabove the water. Sunlight is incident at angle 胃=55.0掳. What is the length of the shadow of the pole on the level bottom of the pool?

High-power lasers are used to compress a plasma (a gas of charged particles) by radiation pressure. A laser generating radiation pulses with peak power 1.5脳103MWis focused onto 1.00 mm2 of high-electron-density plasma. Find the pressure exerted on the plasma if the plasma reflects all the light beams directly back along their paths.

In Fig.33-38, a laser beam of power 4.60W and diameter d=2.60mm is directed upward at one circular face (of diameter d<2.60mm) of a perfectly reflecting cylinder. The cylinder is levitated because the upward radiation force matches the downward gravitational force. If the cylinder鈥檚 density is 1.20 g/cm3, what is its height H?

In the figure, initially unpolarized light is sent into a system of three polarizing sheets whose polarizing directions make angles of胃1=胃2=胃3=50掳with the direction of theyaxis. What percentage of the initial intensity is transmitted by the system? (Hint: Be careful with the angles.)

Figure:

One want to rotate the direction of polarization of a beam of polarized light throughby sending the beam through one or more polarizing sheets.

(a) What is the minimum number of sheets required?

(b) What is the minimum number of sheets required if the transmitted intensity is to be more than60%of the original intensity?
