The first step to getting output from a laser is to excite an active medium. What is this process called?
-
Pumping
-
Exciting
-
Priming
-
Raising
Laser pumping is the process of supplying energy from an external source to transfer electrons into excited states within an active laser medium, achieving the population inversion required for stimulated emission of light.
To answer this question, you need to understand the process of generating output from a laser. Let's go through each option to understand why it is correct or incorrect:
Option A) Pumping - This option is correct because the process of exciting an active medium in a laser is called pumping. Pumping involves supplying energy to the active medium, such as a solid, liquid, or gas, to raise electrons to higher energy levels.
Option B) Exciting - This option is incorrect because while it describes the general concept of the process, the specific term used in the context of lasers is "pumping."
Option C) Priming - This option is incorrect because priming is not the term used to describe the process of exciting an active medium in a laser.
Option D) Raising - This option is incorrect because while it describes the general concept of raising electrons to higher energy levels, the specific term used in the context of lasers is "pumping."
The correct answer is A) Pumping. This option is correct because it accurately describes the process of exciting an active medium in a laser.
