✦ Synopsis
Depending on whether the measurements are performed at temperatures lower or higher than -O.Ol"C, the photoinduccd thermal lens in water can have either positive (converging) or negative (diverging) focal length. At precisely -0.0 1 k 0.04" C, no thermal lens signal could be observed. This is because at this temperature, the refractive index of water is maximum of the temperature coefficient of the refractive index, dn/dT, is zero.
