  Hi,
  I am simulating a laser system, but I have encountered a question: which indicator of TWLM model should I adjust to achieve the effect of increasing output light intensity? Dear engineer, could you give me some guidance？

  Hi,
  The TWLM model is to perform the physical simulation of laser. So, you cannot directly control the intensity of light output.
  Several input parameters can control the output light including the drive current, the gain spectrum/optical losses, the facet reflectivity and so on. So, if you want to simulate how the laser output such as the power changes as a function of such inputs you can use TWLM but you cannot directly control the light output.
