“…Since the time and space of discharges can be accurately controlled, many applications based on laser-induced filament were developed [185,186]. Polynkin et al [187] reported a multi-pulse scheme for laser-guided electrical breakdown of air, which is shown to be suitable for guiding discharges propagating in either direction or along curved paths.…”

The applications of femtosecond lasers to the diagnostics of combustion and flow field have recently attracted increasing interest. Many novel spectroscopic methods have been developed in obtaining non-intrusive measurements of temperature, velocity, and species concentrations with unprecedented possibilities. In this paper, several applications of femtosecond-laser-based incoherent techniques in the field of combustion diagnostics were reviewed, including two-photon femtosecond laser-induced fluorescence (fs-TPLIF), femtosecond laser-induced breakdown spectroscopy (fs-LIBS), filament-induced nonlinear spectroscopy (FINS), femtosecond laser-induced plasma spectroscopy (FLIPS), femtosecond laser electronic excitation tagging velocimetry (FLEET), femtosecond laser-induced cyano chemiluminescence (FLICC), and filamentary anemometry using femtosecond laser-extended electric discharge (FALED). Furthermore, prospects of the femtosecond-laser-based combustion diagnostic techniques in the future were analyzed and discussed to provide a reference for the relevant researchers.

We present space and time resolved measurements of the air hydrodynamics induced by femtosecond laser pulse excitation of the air gap between two electrodes at high potential difference. We explore both plasma-based and plasma-free gap excitation. The former uses the plasma left in the wake of femtosecond filamentation, while the latter exploits air heating by multiple-pulse resonant excitation of quantum molecular wavepackets. We find that the cumulative electrode-driven air density depression channel plays the dominant role in the gap evolution leading to breakdown. Femtosecond laser heating serves mainly to initiate the depression channel; the presence of filament plasma only augments the early heating.

NiFe‐Materialien sind hervorragende Elektrokatalysatoren für die Sauerstoffentwicklungsreaktion (OER). Zur Entwicklung effizienterer Katalysatoren werden umfangreichere Kenntnisse zur Aktivitätssteigung der OER sowie über deren Mechanismus benötigt. Dafür sind In‐situ‐Charakterisierungsmethoden erforderlich, die Untersuchungen unter OER‐Bedingungen ermöglichen, um Zwischenprodukte der OER sowie OER‐aktive Zentren und Phasen zu identifizieren. In diesem Kurzaufsatz werden die neuesten Fortschritte bei der In‐situ‐Charakterisierung von NiFe‐basierten Elektrokatalysatoren mit Raman‐Spektroskopie, XAS, APXPS, Mößbauer‐Spektroskopie, UV/Vis‐Spektroskopie, DEMS und SI‐SECM zusammengefasst. Die Ergebnisse belegen nicht nur die Strukturumwandlung und fortschreitende Oxidation der katalytischen Spezies unter OER‐Bedingungen, sondern auch die entscheidende Rolle von Ni und Fe. Die Notwendigkeit für die Entwicklung neuer In‐situ‐Methoden und Rechnungen zum OER‐Mechanismus für die gezielte Entwicklung neuer, hochaktiver OER‐Elektrokatalysatoren wird diskutiert.
