Chapter 15, Problem 15.67E

Interpretation Introduction

Interpretation:

The power of a laser emitting $\text{300-millijoule}$ pulse in $\text{2}\text{.50}\text{nanoseconds}$ is to be calculated.

Concept introduction:

Laser is a device that has a full name of “Light Amplification by Stimulated Emission of Radiation”. Laser gives light after the amplification process. The energy of light after the amplification process is so high that this light can be used to cut a thick metal sheet. Taking the advantage of this, a device has been developed known as laser. This technology of laser is widely used in space.
