A simple algorithm for solving the finite-difference (FD) equations for the mode eigenvalues and field distributions of a linear waveguide is presented. By applying the discretized Helmholtz operator column-by-column to an index distribution defined

We present a general form of master equation for nonlinear-optical cavities that can be described by an ABCD matrix. It includes as special cases some previous models of spatiotemporal effects in lasers.

A ring resonator containing a Kerr lens and a Gaussian slit is analyzed. From the point of view of Kerr lens mode locking, it is shown that a self-defocusing nonlinear element is as effective as a self-focusing one and that the positioning of the Ker

Pulse generation in a two-photon laser is investigated theoretically. A simple model including dispersion, linear absorption, and two-photon saturable gain yields stable mode-locked pulses with a sech2 intensity profile. Unlike as with self-phase-mod

One of the unique features of nonlinear planar waveguides is that spatial solitons can be emitted into a self-focussing cladding medium. In this paper we discuss this phenomenon for a variety of models for the nonlinear medium, and show that soliton

We present a simplified local-mode analysis of the nonlinear directional coupler. This novel approach predicts a splitting in the transfer function when assuming different signs for the nonlinearity, in agreement with the results of the Beam Propagat

We propose a new mean-field or master equation capable of describing transverse effects, pulse evolution and nonlinearity in an appropriate cavity. It is developed with a view to modeling Kerr lens mode-locking, but promises much wider applicability.

We show numerically that solitary waves, localized in two transverse dimensions, are emitted when a high‐power Gaussian beam is launched into a slab waveguide in which the cladding displays a saturable self‐focusing nonlinearity.

There has been much recent interest in using a nonlinear lensing element combined with an aperture to produce a saturable absorber for laser modelocking. [1, 2] This Kerr-lens-modelocking (KLM) technique normally uses the gain medium as the nonlinear
