Latest Patents

Among his latest patents, Mar has developed a multi-line triggering and interdigitated electrode structure for photoconductive semiconductor switches. This innovative switch design allows for multiple-line optical triggering of high-current parallel filaments between the switch electrodes. By increasing the number of current filaments, the switch can achieve a longer lifespan at high currents while reducing the current density at the contact electrodes. This improvement also helps mitigate the degradation of switching conditions with repeated firings.

Another significant invention by Mar is a new type of semiconductor light source that produces high peak power output without relying on injection, e-beam, or optical pumping. This light source, based on current filaments, can generate high-quality coherent or incoherent optical emissions. The electron-hole plasma formed within the current filament can be several hundred microns in diameter and several centimeters long, allowing for potentially large energy per pulse. Immediate applications for this technology include high-energy, short-pulse, compact, and low-cost lasers.
