Quartz Thickness (,urn)
Figure 2.8: Calculated ~laker fringes with a broadband source as a function of quartz
thickness. The light generating source is a Ti:AI 2 0 3 laser. The ~laker fringes damp
out as the quartz slab gets thicker.
the material becomes more dispersive. or the pulse duration of the laser decreases.
i.e. the bandwidth increases.
;..iote. the index of refraction and the group velocity were derived from the Laurent
expression for the ordinary index of refraction of quartz
(2.67)
The parameters for equation (2.67) are displayed in Table 2.3.
