"><p>Laser model. </p>
<p>Basic algorithm:</p><ol type="1">
<li>FM noise PSD is generated in the frequency domain</li>
<li>FM noise PSD is converted to time domain using IDFT</li>
<li>FM noise PSD is convolved with white Gaussian noise</li>
<li>PM noise is generated by integrating FM noise The length of the FM noise PSD is specified in model.Lpsd, or in the constructor, param.L. Noise at the lowest frequency component (DC) is forced to zero unless L=1. This means phase noise will be zero-mean unless L=1.</l
