Each mirror as this settings :
photons { target refraction off reflection on collect off }

No, the light source for the beam is out of the "projector".

I have an other light source. Kind of "global illumination" for the
scene. for her setting is :
photons { refraction off reflection off } media_interaction off

Yes, there is only one light source for the laser with
photons { refraction on reflection on }

The global media is defined like this :
box {
<32, 0, -1>, < -1, 6, 32> // 28>
hollow
texture { pigment { color rgbf 1 } }
interior {
media {
scattering {
1,
color White
extinction 0
}
method 2 // uniform
intervals 2
samples 4
}
}
photons { target }
}
