Problem 6 (30 points): Two femtosecond laser pulses have a wavelength of

Problem 6 (30 points): Two femtosecond laser pulses have a wavelength of 800 nm. Both pulses travel the same distance from point A to point B. An unknown material of thickness 0.5 mm is introduced in the path of one of the pulses. The dispersion relation for this material is o = = 20k. (a) What is the time difference between the arrival time at point B for the two pulses? This is the same as the delay between the envelopes of the two pulses and is called group delay (hint: calculate group velocity) (15 points) (b) What is the phase delay between the two pulses expressed in seconds? This is the same as the delay of the wave oscillations within the envelope. (15 points)
