RP Fiber Power – Simulation and Design Software for Fiber Optics, Amplifiers and Fiber Lasers

The Ultimate Tool for Developing Fiber Lasers and Amplifiers

Simulate fiber lasers and amplifiers in no time,
understand how they really work,
boost the quality and efficiency of your development!

RP Fiber Power is a powerful software for simulation, design and optimization of fiber devices – in particular, fiber amplifiers and lasers as well as other types of waveguide lasers (and even many bulk lasers) , but also fiber couplers, multi-core fibers, helical core fibers and tapered fibers. (See below for typical application areas.)

The software offers both efficient power propagation and full numerical beam propagation. Ultrashort pulse propagation can also be studied, for example in fiber amplifier systems, mode-locked fiber lasers, telecom cables and automatically optimized pulse compressors.

RP Fiber Power is

  • an enormously versatile tool for power users,
  • but at the same time (particularly since V8 with Power Forms) also easily usable for those who are not (or not yet) experts in the field.

It is a must-have for anyone seriously dealing with fiber devices – be it in industrial development, scientific research or in education. Its user interface combines uttermost flexibility with an easy start. It is therefore equally well suited for efficient routine checks and for most sophisticated simulation work.

RP Fiber Power V8

V8 brought a breakthrough in terms of usability!

With its crucial new feature of Power Forms, this Version reaches a new level in terms of combining power, flexibility and ease of use. Essentially, these are easy-to-use forms that we provide for a nice set of extensible simulation models, covering a wide range of application areas of the software.

Great Handling

Start your first simulations in no time!

  • Just fill out the appropriate form, e.g. the one for ultrafast fiber amplifier systems. Set the relevant parameters and the desired outputs (mostly diagrams). Then run the simulation and inspect the beautiful and highly informative output!
  • You can simulate even complex fiber amplifier systems with multiple amplifier stages, each with multiple pump sources, multiple input signals (continuous wave, short pulse, or ultrashort pulse), etc.
  • The forms are very nicely designed to be easy to use despite their richness of features. For example, currently irrelevant parts of the forms are hidden, and many output fields display helpful hints when the mouse pointer is over them.
  • Comprehensive documentation is available with a single keystroke. You can read exactly what is simulated and how to configure everything.

Amazing Flexibility

Get what you need - even what we did not anticipate!

Form-based user interfaces are common – but often not flexible enough to do real work. For example, what if you need an extra curve on a graph, an entirely new graph, or an advanced simulation with additional inputs?

With RP Fiber Power V8, we have made a breakthrough in how to achieve great flexibility:

  • To add an extra curve to a diagram, just add a single line of script code to the form. (We are happy to help you.)
  • For an entirely new diagram, enter a few lines of script code into the form.
  • For extensive post-processing of the results, including generating output files in a custom format, call an external custom script with a single line of code in the form.
  • For even more complex extensions, you can easily create a customized version of a form. This can, for example, have additional input and output fields and perform additional calculations related to them.
  • For doing very special things, outside what is covered by all our Power Forms, there is still the option to develop your own Simulation Scripts, which can also be equipped with forms for easy handling.

And our diligent technical support means that you will not be left alone!

Not a simulation guru yet? Don't worry:

  • If you can build a laser or amplifier in reality, you can surely simulate it with this software.
  • When in doubt, the high-quality documentation will tell you exactly what is needed, what effects the model takes into account, etc.
  • Our diligent technical support won't leave you alone if you encounter problems! We support you even beyond software-specific problems.

Your personal professional development can soon be greatly enhanced: if you become the one who quantitatively understands these devices, you will play a key role in your team.

Start Doing Excellent Development Work

You should now get the right tool to take your design work to a new level of quality, efficiency, and creativity:

  • Before ordering parts, testing your prototype, diagnosing and troubleshooting in the lab, simulate your prototype laser or amplifier on your PC. There you can eliminate many problems in no time!
  • Only then is it time to order the parts and build and test the device in the lab.
  • If you encounter problems later, use the simulations again to quickly diagnose and find solutions.

You can soon save a lot of time and money, and also develop new creative solutions.
