Intrinsically in FFT code, the Gouy phase is automatically calculated. For design purpose, we would like to calculate the accumulated Gouy phase as the beam propagates. The function attached calculates the Gouy phase of a TEM00 beam for a propagation length defined by the user. The principle behind it is to calculate the phase of […]

Some tips how to use OSCAR
I have defined my cavity but when I do a scan over one FSR, I can see the presence of some second order modes. Or when I look at the reflected power, I can see a mode LG10 or I do not have the maximum power gain. All that may indicate that the mode matching […]
