One method of creating an inverted population is known as _ and consists of illuminating the laser material with light.
Correct answer: A. Optical Pumping
- A. Optical Pumping
- B. Excitation
- C. Bremsstrahlung
- D. Holography
Explanation
Optical pumping suggests that the method of creating an inverted population is called optical pumping. Optical pumping is a technique where the laser material is illuminated with light to excite the atoms or molecules, causing them to populate higher energy levels. This population inversion is necessary for the operation of a laser.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
