Laser Studies of Metal Cluster Beams

Laser-generated ultrasonic beams.

Nonlinear combining of laser beams.

We propose to combine multiple laser beams into a single diffraction-limited beam by beam self-focusing (collapse) in a Kerr medium. Beams with total power above critical are first combined in the near field and then propagated in the optical fiber/waveguide with Kerr nonlinearity. Random fluctuations during propagation eventually trigger a strong self-focusing event and produce a diffraction-l...

Axicon Gaussian Laser Beams

If a laser beam is to have radial transverse polarization, the transverse electric must vanish on the symmetry axis, which is charge free. However, we can expect a nonzero longitudinal electric field on the axis, considering that the rays of the beam that converge on its focus each has polarization transverse to the ray, and hence the projections of their electric fields onto the axis all have ...

Laser beams and resonators.

This paper is a review of the theory-of laser beams and resonators. It is meant to be tutorial in nature and useful in scope. No attempt is made to be exhaustive in the treatment. Rather, emphasis is placed on formulations and derivations which lead to basic understanding and on results which bear practical significance.
