In this thesis, the Group Velocity Dispersion (GVD) of air has been measured by using a femtosecond frequency comb at 1.5 µm. By comparing the spectra from a balanced and unbalanced Mach - Zehnder interferometer, the need for vacuum tube is eliminated. The method employs the Fast Fourier Transform of both auto- and cross correlation to find the spectral and their differences. The GVD of air is then calculated from these spectral phase differences. With twenty-five independent measurements, the GVD of air was found to be 0.0120 fs²/mm, with a standard deviation of 0.0075 fs²/mm.

Whiter and brighter images. Simply put, that is the benefit of the Tele Vue Everbrite mirror coating. This exotic, dielectric, nonmetallic coating is 99% reflective across the full visual spectrum, resulting in the "whitest," and most natural image available. The coating is painstakingly applied to Pyrex, with a surface accuracy of 1/10 wave flatness. A superior flat mirror is what you want when you need to obtain the best optical image performance from your telescope system!
