- Hydrogen peroxide (H2O2) is for the first time measured and imaged in two-dimensions in an HCCI engine using photofragmentation laser-induced fluorescence (PF-LIF). Qualitatively, the experimental data agree with simulations.

- Laser-induced breakdown spectroscopy (LIBS) is an experimentally simple method capable of measuring elemental composition in a flame. Moreover, the breakdown threshold energy is temperature dependent. Hence, LIBS allows multiple parameter determination in combustion environments.

- An all-fiber nanosecond Kerr light gate is described that was constructed using microstructured fibers. The switching voltage for a 20 cm long device is as low as Vp ∌ 85 V at a 1.06 Όm wavelength. The device is fully spliced. The active element is a three-hole fiber provided with internal electrodes in the side-holes and a liquid core of nitrobenzene, which is fully enclosed. This work allows the exploiting of electrically driven liquid-core fibers and demonstrated the removal of the major limitations of Kerr cells in the past, allowing for integration, safe use, and relatively low switching voltage.
