Laser ignition (LI) of both liquid fuels and gaseous combustible mixtures in gas turbines offers the potential for reduced emissions and increased reliability. During the combustion process, carbon and other by-products accumulate on the walls of the combustion chamber. For laser based ignition systems, this could potentially reduce the transmissive propertie...$28.00

Presented at ICALEO 2012
Ultrafast laser microprocessing is a key and growing technology for a number of industrial applications such as thin-film photovoltaics, scribing very hard materials, and some niche marking applications. Ultrafast lasers are capable of athermal material modification, such as laser-induced periodic surface structures (LIPSS) and black silicon, which opens up interesting marking regimes that are not easily accessed by longer pulse sources. We demonstrate the abilit...$28.00

A novel surface processing technique entitled Droplet Opto-hydrodynamic Processing (DOP) technique is introduced [1]. The process is based on the laser-induced breakdown (LIB) of a micro liquid droplet and subsequent ejection of a high-speed micro liquid jet. The speed of the microjet (~1300 m/s) is sufficiently high to remove nanoscale...$28.00
