Exhumations of the victims of Franco's repressive policies are cultural practices of tremendous heuristic value and allow for the analysis of the public emergence, circulation and consumption of traumatic memory in local contexts. The use of visual media to capture social action in the surroundings of the exhumations serves as both a recording and as a triggering device for this emerging social...

The power supply of flash lamp-pumped a Nd: YAG solid-state laser basically consists of a trigger circuit which initiate the ionization of the gas into the lamp, a simmer circuit that keeps the ionized gas with a low-level dc current and a main discharge circuit where a storage capacitor is discharged into a flash lamp to pump the Nd:YAG laser. The impedance of the flash lamp presents a nonline...

We analyze the high-temperature continuous-wave performance of 1.3m AlGaInAs/InP laser diodes grown by digital alloy molecular-beam epitaxy. Commercial laser software is utilized that self-consistently combines quantum-well bandstructure and gain calculations with two-dimensional simulations of carrier transport, wave guiding, and heat flow. Excellent agreement between simulation and measuremen...

We report experimental guiding of high-voltage (HV) sparks discharges in air with plasma filaments generated by a terawatt femtosecond laser. Large sparks discharges are shoot up from a HV electrode fixed at the top of a Tesla coil voltage elevator to a farther grounded one. Ultrashort laser pulsed beams of energy on the order of the mJ through open air exhibit non-linear propagation effects. I...

We experimentally observed laser-induced remote high-voltage discharge triggering between two needle electrodes with half-a-cm spacing. The was initiated by a 744-nm, 90-fs, 6-mJ laser pulse undergoing filamentation in air. For the direct voltage below self-breakdown threshold, of air-gap synchronized 10-Hz repetition rate and occurred 40 80 m propagation path. No guiding observed. registered s...
