Excimer lasers are powerful sources of radiation in the UV, providing several laser lines between 157 and 353 nm. The excimer laser transition is bound-free, and thus the emitted wavelengths are broad-band (up to 200 cm−1). In addition the high gain (0.15 cm−1) of the laser gas causes a rather large divergence (>1 mrad) in conventional excimer lasers.A new excimer laser concept is described which improves the spectral brightness in terms of watt/(rad × bandwidth) by three orders of magnitude. This allows, through non-linear processes such as Raman shifting the fundamental output and four-wave-mixing in gases, the generation of new laser lines in the UV and VUV.

A number of transparent liquids have been evaluated for use in stimulated Brillouin scattering at 532 nm. Measurements were made of frequency shift, SBS threshold, reflectivity and optical breakdown properties. It was found that the alkanes, and in particular n-pentane, performed well and measurements were made of Brillouin gain coefficient and phonon lifetimes. It is suggested that these liquids are promising candidates for use in self-pumped phase conjugate mirrors, high gain Brillouin amplifiers and four-wave mixing mirrors.

We investigate highly efficient frequency-degenerate parametric generation through inverse four-wave-mixing (IFWM) in silicon nanowaveguides, which exhibits distinctly from traditional FWM phenomenon and manifests itself as a unique process producing signal and idler photon pairs with frequencies at the center of two pumps. The influences of dispersion, nonlinear coefficient and frequency detuning on the IFWM process are numerically analyzed in detail. On this basis, the optimal condition for high gain IFWM and the nanowaveguide with high nonlinearity and large normal dispersion are proposed. These results substantiate the feasibility of such frequency-degenerate parametric generation in CMOS-compatible integrated platforms, which could find important potential in signal-processing systems for photonics networks and entangled qubits generation for quantum optics.
