A quantum mechanical form of the Cramer-Rao inequality and a minimum-mean-square-error quantum estimator for multiple parameters are derived, allowing all possible quantum measurements of theâ€¦ (More)

To deal with sharply cut off fields at mirror edges, a continuous Fourier integration procedure is described. A spline fit is made to the discrete data, followed by analytic integration of the splineâ€¦ (More)

An explicit evaluation is made of a simple end correction to the quasi-fast Hankel-transform algorithm. Application to a Gaussian beam shows that for a given accuracy, the use of this end correctionâ€¦ (More)

The electromagnetic field distribution in a laser resonator is obtained by the numerical solution of the paraxial wave equation with nonlinear saturated gain. In unstable resÂ onators the edgeâ€¦ (More)
