It has been shown in the past that pulsed laser systems operating in the so-called “burst mode” are a beneficial approach to generate high peak power laser pulses at high repetition rates suitable for various applications. So far, most high-energy burst-mode laser systems put great effort into generating a homogeneous energy distribution across the burst duration, e.g., by shaping the pump puls...

A Grazing Incidence Metal Mirror (GIMM) is a chief candidate for beam delivery for Inertial Fusion Energy (IFE). The goal for GIMM survival is greater than 3 10 8 laser pulses with 5 J/cm 2 laser fluence normal to the incident beam. Laserinduced damage to metal mirrors is primarily a thermomechanical process. Long-term exposure leads to microstructural evolution analogous to fatigue. We have pe...

Time-resolved observations of a 6′ x 6′ field, containing the position error boxes of the X-ray source 1WGA J1958.2+3232, were performed in June 1999 with the 91 cm Catania telescope, equipped with a Photon Counting Intensified CCD. The star recently proposed as the optical counterpart of the 1WGA J1958.2+3232, exhibited a strong optical modulation with a period compatible with that seen in X-r...

The effective permittivity dyadic of a composite material containing particulate constituent materials with one constituent having the ability to display the Pockels effect is computed, using an extended version of the strong–permittivity–fluctuation theory which takes account of both the distributional statistics of the constituent particles and their sizes. Scattering loss, thereby incorporat...

An optical bunch-by-bunch beam diagnostic system, which can detect oscillations of individual bunches in a multi­ bunch operation, has been developed. The system is com­ posed of a high-speed light shutter and an optical beam­ oscillation detector. The shutter that consists of a pockels cell and polarizers can be opened or closed in a bunch spac­ ing time (2ns in KEK-PF) and it can select a lig...

he main objective of this paper is to present a detailed study concerning the modeling of passive optical devices, controlled by the linear electro-optic Pockels effect [1]-[8], particularly the Mach-Zehnder devices. First it is studied the anisotropic media in general where is deduced the electro-optic tensor and the appropriate indexes ellipsoid expressions to a crystal such as lithium niobat...

The Pockels effect in periodically poled lithium niobate made it possible to switch optical signals between two orthogonal optical linear polarizations of the vertical and horizontal polarization states. Based on this effect, we demonstrated polarization-based binary optical logic gates: AND, and OR gates. By combining these basic gates with other polarization-based optical logic gates such as ...

In this work, a novel highly fabrication tolerant polarization beam splitter (PBS) is presented on an InP platform. To achieve the splitting, we combine the Pockels effect and the plasma dispersion effect in a symmetric 1x2 Mach-Zehnder interferometer (MZI). One p-i-n phase shifter of the MZI is driven in forward bias to exploit the plasma dispersion effect and modify the phase of both the TE a...

We report the discovery of a 2.1hr optical modulation in the transient source GS182624, based on two independent high time-resolution photometric observing runs. There is additional irregular variability on shorter timescales. The source also exhibited an optical burst during each observation, with peak fluxes consistent with those of the three X-ray bursts so far detected by BeppoSAX. We compa...
