Figure 3
The path length difference (PLD) and lateral shift (LS) of the crystal as a function of the beam position, calculated based on measurements performed with a profilometer. x > 0 is the case in which the beam is on the flat part of the mirror, and x < 0 is the case in which the beam is on the 1° slope part of the mirror. While the variations in PLD were intended, the variations in LS were not (see text). |
