What Role Does Optical Fiber Play in Fiber Lasers?

AI Thread Summary
Fiber lasers utilize optical fibers as integral components, primarily serving as the lasing medium rather than the resonance chamber. The structure typically involves infrared pumping LEDs that deliver energy through fiber optics to the laser head, where it is used to pump a YAG crystal. While fiber optic cables are essential for transporting optical signals, they are not suitable for the main cavity of the laser. Understanding the specific role of optical fibers in these systems is crucial for grasping their functionality. Overall, fiber lasers represent a unique application of optical fiber technology in laser engineering.

I was wondering if anyone could tell me about fiber lasers. I don't mean those used as transmitters on optical fiber systems; I mean lasers that contain optical fibers as components.

I know that it can be done, but I don't know what the structure is like. What part does the fiber play? Is it used as the resonance chamber, the lasing medium, or something else? If anyone could help me I would be very grateful.

Thank You

I work with http://www.coherentinc.com/Lasers/index.cfm?fuseaction=show.page&id=868&loc=834" These lasers have Infrared pumping LEDs in a remote Power Supply. The Infrared beam is carried through Fiber optics to the Laser head itself. In the laser head the infrared energy is used to pump the YAG crystal.

I do not believe that a fiber optic cable could be used for the main cavity. Fiber optic cables are used to transport a optical signal, they are wire of optical systems.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
