We have developed a means to electronically tune laser pulse durations and achieve nearly constant, stable output power. This technique may be used to obtain variable pulse durations and peak powers at a constant pulse repetition rate, or constant pu

Long-term fertility experiments (LTFEs) are a tool to investigate the sustainability of cropping systems. Several LTFEs for intensive irrigated rice cropping were established in Asia, but those are rare in Sub-Saharan Africa. Two such trials are pres

The massive growth in the usage of renewable, but fluctuating energy sources in connection with the energy turnaround calls for a similar growth of the integration of flexible loads. This seems to be a vital aspect to maintain the balance between pro

Many micromachining operations, particularly in the electronics sector, utilize pulsed solid-state UV lasers. These processes demand high levels of stability, as the yield and quality relate directly to the repeatability of each laser pulse. Critical

The trend in micro-machining lasers is toward greater average power and higher repetition rate, in order to increase throughput, with pulse energy and peak power held roughly constant, as determined by the small scale of the feature. At repetition ra
