Fiber laser filters

[Ebraheem]

Dear all,

I wanna design a fiber laser setup.

For example:
I have a pump laser (light source) with 900 nm wavelength and 1 kW power. The pumping light is coupled into a doped fiber. I need before and after the fiber something like mirrors, which filter special wavelengths. As we know, the phenomenon that emerges in the fiber between the two mirrors is called “lasing”. How can I realize these “mirrors” before and after the fiber in Optisystem? I have found two possibilities “Isolator bidirectional” and “Uniform Fiber Bragg Grating”.

The aim is that the output should be wavelengths between 500 and 700 nm. To realize that, I need a filter in the beginning and at the end of the fiber.

Which component in the component library of Optisystem fits my purpose best?

Thank you in advance.

Hi Ebraheem,
I think one of the options that you can use a “reflector bidirectional” component to build such a Fabry-Perot design.
there is a built-in example titled “Yb Doped Fiber Laser”, that might be a good prototype to start with to build your project.
hope that helps
best of luck
