$tracephase is an experimental commands for tracing the phase of the photon. <br> 

 $tracephase
 type
 wave_length  (initial_phase)  

 If type =1, just set the wavelength of the light
 If type =2, decide the wave length and the initial phase

For example 

 $tracephase
 1
 450.0

or


 $tracephase
 2
 450.0  0.23
