Each student assigned is asked
to prepare a set of lecture notes to be distributed
to other students before the presentation.
Questions that you want to be able to answer are now given under each lecturer. (4/24/00)
The approval date is the date that you are supposed to
show me the writeup material that you
are to hand in to the students.

6.1; 6.2 pp195-209 (two lectures) Seunghee Lee, 3/9 (3/3)
1. . The expression of linearly, circularly, and elliptically polarization.
2. Polarization devices. I introduced three kinds of devices: polarizers, wave retarders, and rotators.
3. Jones vectors represent the polarized light in matrix form, and one matrix represents the optical devices.
1. Coefficients of reflection and transmition for both TE and TM in terms of refraction index, incident angle and transmitted angle.
2. Reflection coefficient, phase shift (between incident and reflected waves) versus incident angle for TE and TM in both case of external and internal reflection.
3. The critical angle and the Brewster angle.
1. Refractive indices and corresponding index ellipsoid.
2 Propagation of light in a media along one of the principal axis and normal modes for that case.
3 Propagation of light in a media in an arbitrary direction and dispersion relation. Also know the directions and magnitudes of K vector, Poynting vector.
Notes on Optical Activity, Faraday Effect and Optics of Liquid Crystals
All the three concepts above deal with polarization rotation. The rotation is measured by rotatory
power, which is defined as angle rotated per unit length.
optical activity - for certain materials that rotate polarization naturally
faraday effect - for materials that rotate polarization when out in a magnetic field
liquid crystals - (fluid state of matter) when an external force is applied the orientation of the
molecules, thus the polarization change.

Important part: part A
1. what's a population inversion?
2. the concept of a rate equation
3. what's the difference between the principles of 3-level and 4-level
puming schemes? What's the restrictions of 3-level schemes' pumping rate on
order to have a population inversion?
1. Laser amplification and gain coefficient
2. Feedback and loss
3. Gain condition and phase condition.
1) Expression for the Steady-State Photon-Flux density both in terms of
initial gain and loss coefficients, and in terms of population differences.
2) Output Photon-Flux Density and its optimization by choosing the mirror transmittance.
3) Qualitative understanding of Spectral Distribution of the Output Light
for homogeneously and inhomogeneously broadened medium, Spectral Hole Burning, Lamb Dip.
1. how does the spatial distrbution affect the laser oscillation?
(because of different spatial distribution, different transverse modes have different gains and losses.)
2. mode competition.
3. select a laser line: using prism, select a transverse mode: using aperture,
select a longitudinal mode: change the loss coefficient or changed.
select a polarization: using Brewster Windows, and why use internal polarizer, not external polarizer?
4. built-in population inversion.
1. wave equation in a nonlinear medium, eq. (1.6).
2. How to make: Second Harmonic generation, three-wave mixing
3. Third hamonic generation, four-wave mixing
4. explain self-phase modulation, self-focusing and optical solitons
Explain electro-optic effect. Explain how to make use of it as phase modulators,
wave retarders, intensity modulators, scanner and spatial light modulators.
