The laser gain medium is a crucial component in a laser system, responsible for amplifying light through stimulated emission. It determines the laser's wavelength, efficiency, and operational characteristics, making it essential for tailoring lasers to specific applications.

amplifying light

Stimulated emission is a process where an incoming photon induces an excited electron to drop to a lower energy level, emitting a second photon with the same phase, frequency, polarization, and direction as the incoming photon. This principle is fundamental to the operation of lasers, where it leads to the amplification of light.

Laser efficiency refers to the ratio of the output power of a laser to the input power required to operate it, essentially measuring how effectively a laser converts energy into light. High laser efficiency is crucial for applications requiring minimal energy consumption and heat generation, such as in medical surgeries and telecommunications.
