Modeling pulsed and CW thulium-doped optical amplification
— analyze critical parameters to enhance amplification performance
Can you quickly model optical amplification in rare-earth-doped materials? Do you know the critical parameters of the material that make the output amplification optimal? Does your current software allow you to easily set up arbitrary energy level diagrams for your material?
With SimphoSOFT®, users can easily set up an energy level diagram of arbitrary complexity for your rare-earth-doped material, add or subtract energy levels or optical transitions in an easy-to-use graphical user interface and run simulations right away – no additional scripts or code is necessary when the diagram is updated. This is very important for rare-earth-doped materials that can have many active energy levels and undergo several types of energy transfer processes. What if you want to change the parameters for the pump beam or seed pulse to see how the output amplification changes? Which parameters do you choose?
We will show two examples of amplification in thulium-doped materials using SimphoSOFT’s Multi-Beam feature. The thulium ions will be pumped to an excited state that can relax via several different pathways. The most important relaxation pathway is cross-relaxation to an intermediate state where stimulated emission can occur. In one example, we will amplify a short pulse that is in the nanosecond time range. In the second example, we will show how to model an approximately continuous-wave (CW) interaction in a thulium-doped material.
The main goal is to localize critical photo-physical parameters of the material to enhance amplification performance. In both cases, you will see how to set up the material models and how analyze the amplification performance of the material based on the calculated populations of the thulium energy levels during the process.
In addition, we will describe the SimphoSOFT Multi-photon Absorber Material Database that will soon be available from Simphotek and that has over 1000 molecule entries.
