2. Consider a laser producing a train of pulses at λ=1060 nm with duration At, = 50 fs and repetition rate frequency fm. The pulses propagate through a 10 cm long piece of glass. The duration of the pulses after the glass are measured to be 100 fs. Calculate the group-velocity dispersion parameter at the laser center frequency B2 of the glass.
