“…High-intensity petawatt laser facilities that deliver multipicosecond (ps) kilojoule (kJ) laser pulses have become available, such as OMEGA-EP [20], LFEX [21], PHELIX [22], PETAL [23], and NIF-ARC will become available soon [24]. In this new multi-ps kJ regime, the nature of preplasma heavily evolves with time, instabilities and self-generated electromagnetic fields grow significantly, thus the dynamics of LPI and the characteristics of fast electron generation are inherently different from those in the sub-ps regime.…”

Abstract. We improved diagnostic instruments to measure X-ray images in a hard X-ray harsh environment and succeeded in obtaining clear images with X-ray framing camera and X-ray streak camera in fast ignition experiment conducted in 2011 (FG-02 Experimental Campaign). We found that high-energy X-ray signals could be used as an indicator of the LFEX laser injection time relative to the imploded core. The LFEX laser injection time was estimated with better than 10 ps accuracy. Time-resolved 2D X-ray images suggested that shapes and motions of imploded core plasmas were improved by changing the configuration of the implosion lasers.

“…Nevertheless, due to poor relative stability and low thermal conductivity, Tb-doped glasses could not be employed in high-power lasers [16]. For another, TGG crystal, as a crystalline MO material, is a congruently melting material and therefore can be synthesized by the Czochralski (Cz) method.…”

Pr 9.33 (SiO 4 ) 6 O 2 crystals have been grown by the Cz-method for the first time for near UV-visible Faraday rotation applications. Rietveld refinement of XRD data demonstrates that the compound crystallizes in the oxyapatite structure with space group P6 3 /m, with oxyapatite structure. In contrast to Tb 3 Ga 5 O 12 , Pr 9.33 (SiO 4 ) 6 O 2 crystal shows a higher transparency in the UV-visible wavelength region, and a shorter cutoff at 270 nm. The Faraday rotation performance and the temperature-dependence of the field-cooled (FC) and zero-field-cooled (ZFC) magnetic susceptibility have been investigated, which indicate that the Pr 9.33 (SiO 4 ) 6 O 2 crystal exhibits paramagnetic behavior in the experimental temperature range from 2 to 300 K and yields a larger FR angle which rapidly increases towards the cutoff. Pr 9.33 (SiO 4 ) 6 O 2 crystal is therefore a promising magneto-optical crystal in particular for potential FR applications in the near UV-visible spectral region.
