~2nm aer ~10 s of irradiation, which corresponds to a defocus term of approximately
5km for a spherical surface.
For comparison, Figure 17.16b shows the wavefront deformation of a CaF

sam-
ple recorded under identical conditions. In contrast to fused silica, which always
exhibits a positive lens eect, the wavefront deformation in CaF

shows a reversed
sign representing a negative lens. is can be explained by the negative dn/dT value
of CaF

. It is interesting to note that, despite an almost 40 times larger expansion
coecient as compared to quartz, the negative change of refractive index with tem ...
