1) A laser produces light of wavelength 525 nmnm in an ultrashort pulse.
What is the minimum duration of the pulse if the minimum uncertainty in the energy of the photons is 1.0%%?
Express your answer with the appropriate units.
Pulsed lasers have many applications, but are very complicated to construct. One problem is
chromatic aberration, another is aligning the components. Commonly available laser systems can
produce 1 fs (10-¹4 s) pulses.
a) how far does light travel in 1 fs?
b) If the energy per pulse is 100 mJ, what's the power per pulse (in Watts)?
c) calculate the (minimum) spread of frequencies required to produce a 1 fs pulse.
d) if the center wavelength is 1 um, what is the range of wavelengths contained in a single pulse?
e) common varieties of optical glass have a dispersion An/A2 = 0.025/micron.
1) if the index of refraction is 1.51 for λ = 1 um, what is the value of 'n' for the upper and lower
wavelength?
2) the focal length of a lens is inversely proportional to the index of refraction: 1/f~ (n-1). What
is the ratio of the focal lengths for the two extreme wavelengths?
3) how much longitudinal chromatic aberration (the difference in focal length between two
colors) is there for a 100 mm focal…
The spacing between rows of atoms in a nickel crystal is 0.215 nm. In the DavissonGermer experiment using a nickel crystal, a second-order beam is observed at anangle of 55°. For what value of accelerating voltage does this occur?
