The process of exciting the active medium in a laser is called pumping. This involves adding energy to the system (via light, electricity, or other means) to raise atoms to excited states so they can emit coherent light through stimulated emission.
To answer this question, you need to understand the process of generating output from a laser.
The correct answer is A) Pumping. This process involves supplying energy to the active medium of a laser in order to excite its atoms or molecules into a higher energy state. This excitation process is necessary to achieve population inversion, which is crucial for the production of stimulated emission and the amplification of light in a laser. Once the active medium is pumped and reaches the necessary energy level, it can produce stimulated emission and generate the laser output.
