Chapter 31: Q. 22 (page 901)

A $1000 W$ carbon-dioxide laser emits light with a wavelength of $10 m m$ into a $3.0 - m m -$ diameter laser beam. What force does the laser beam exert on a completely absorbing target?

Short Answer

Expert verified

Force, $F = 3.33 \cdot 10^{- 6} N$

Step by step solution

LASER

A laser's basis is built on three distinct elements: stimulated emission within an amplifying medium, population inversion of electronics, and an optical resonator.

Find force exerted by beam

The power is $P = 1000 W$ . A simple formula can be used to calculate the force applied by the beam on the entirely absorbing target.

$F = \frac{P}{c}$ ,

where $c = 3.00 \cdot 10^{8} m / s$ is the speed of light. Therefore

$F = 3.33 \cdot 10^{- 6} N$
