Video Demonstrations
The first video shows you how easily the software can be used. A model for an ytterbium-doped fiber laser is obtained by only filling out some form fields. Simply click on the image:
The second video demonstrates what great flexibility is obtained from the integrated script language. With a few lines of script code, put into some form fields, a user-defined diagram is generated which shows the output power of a fiber laser as a function of the pump wavelength, with the fiber length being numerically optimized for each wavelength:
The third video shows how to quickly calculate fiber modes and display their properties:
The fourth video shows some work with a fiber amplifier model. You will see that one quickly learns a lot on the involved physics and the resulting performance limitations:
The fifth video demonstrates dynamic amplifier simulations, i.e., with time-dependent input powers:
More videos are in preparation.
Demonstrations for Models Made with RP Fiber Power
Example Cases Described on Separate Pages
A first set of examples illustrates the power of the mode solver:
- calculating fiber modes
- modes of a germanosilicate fiber, with calculation of dispersion
- launching light into a multimode fiber
Further demo files show how to simulate fiber amplifiers and lasers (only steady-state calculations):
- erbium-doped fiber amplifier
- cladding-pumped high-power ytterbium-doped fiber laser
- thulium-doped blue upconversion laser
- ASE source with automatic spectral optimization
Here are some examples for dynamic simulations:
Finally, there are demonstrations for simulating the propagation of ultrashort pulses:
- higher-order solitons
- soliton self-frequency shift
- parabolic pulses in a fiber amplifier
- regenerative amplifier
- data transmission

Even more demo files (in total more than 25) are delivered with the software. As a user, you can simply copy demo scripts and modify them according to your needs. However, you may also easily generate new scripts using the interactive forms.
Some Nice Graphics
The following graphics, including some animated ones, have all been produced with the RP Fiber Power software only, i.e., not using any additional graphics software.
Figure 1: Intensity profiles of all guided modes of a fiber.
Figure 2: Intensity profile at the end of a multimode fiber for varying position of the input laser beam.
Figure 3: Amplitude profiles of fiber modes for a varying refractive index profile.
Figure 4: Effective refractive indices of a germanosilicate fiber as functions of the wavelength.
Figure 5: Signal and pump power and ASE in a fiber amplifier.
