A refined and simplified version of the beam expansion method for computing the modes of unstable resonators is presented here.The principle of the beam expansion method is to express the field pattern on a basis of Hermite-Gaussian functions. Propag

The potential of the so-called ‘eigenvector method’ (here called the direct eigenvector method (DEM)) for computing the modes of unstable resonators in two transverse dimensions is examined, and a detailed comparison with the traditional Fox–Li

A detailed review of the properties of optically anisotropic materials (both uniaxial and biaxial) is presented. Attention is particularly focused on the biaxial case, and some little-known features of these media are highlighted. Since the optic axe

We present the progress made in developing IOPW OPCPA facility for the Vulcan laser to produce pulses with focused intensities >1023 Wcm-2. This power level will be delivered by generating pulses with >300J in 30fs. These pulses will be delivered to

A novel method of computing the modes of unstable resonators is presented. By writing the modes as a series expansion in a set of orthogonal functions, the problem is reduced to finding how the expansion coefficients change in a circuit of the resona

In the summer of 1961, a landmark experiment was performed at the University of Michigan in which optical second harmonic generation was observed for the first time. This event 50 years ago marked the birth of modern nonlinear optics, and this articl

We establish the connection between a paper by Kartner et al. [F.X. Kartner, D.M. Zumbuhl, N. Matuschek, Phys. Rev. Lett. 82 (1999) 4428] entitled “Turbulence in mode-locked lasers”, and earlier work on the role of noise in mode-locked laser syst

The contrast ratio of the recompressed output pulses in an optical parametric chirped pulse amplification system can be limited by temporal noise on the pump pulse. We present a simple analysis which can be used to estimate both the contrast ratio of

Two different methods for studying transverse effects in nonlinear optical interactions are compared, and their strengths and weaknesses discussed. The simpler split-step approach is found to be less restricted in its capabilities and computationally
