Reply To: can I use 2 sources together?

[Guilin Sun]

if you provide mode details such as device configuration and results you want, maybe I can give you more suggestions.

In theory, you can use more than one source. However please note that they will be coherent. 

If they have different bandspectrum, you may only get accurate result without normalization, or use time domain signal.

If it is nonlinear, you can use two or more sources, please refer to https://optics.ansys.com/hc/en-us/articles/360042192953-Pump-probe-simulation-using-4-level-2-electron-material

Transmission is the ratio of transmitted power over injection power, so it is unitless.

Power will be in Watt.
