IR injection telescope simulation after improvement of homodyne matching

After the improvement of homodyne matching entry #1354, the parameters of the beam entering the injecion telescope have changed (results of measurement in entry #1363).

Parameters changes: 

w0

126um --> 94um

z0 (with respect to PBS)

15 cm --> 8.9 cm

Focal lenghts needed for the new injection telescope are:

600 mm (instead of -1000mm)

750 mm (instead of 500mm)

Robustness is still really good (fig 2).
