Which of these is the primary difference in lasers?
A) The color of the light
B) The nature of the lasing medium
C) The intensity of the light emitted
D) The wavelength of the light emitted
E) The speed at which the light emitted travels

Question

Quizplus · Accepted Answer

The primary difference in lasers lies in the nature of the lasing medium – the type of material used to produce the laser light. Different lasing mediums (such as gas, liquid, or solid-state materials) emit light at different wavelengths and have different properties, which ultimately determine the color, intensity, and other characteristics of the laser beam. While A, C, D, and E can also affect the properties of a laser, they are secondary to the nature of the lasing medium.
