Le lieu vide. Democrazia e Totalitarismo in Claude Lefort
No full textTra gli intellettuali del XX secolo Claude Lefort si è distinto per l’acume e l’originalità con cui ha affrontato le principali questioni filosofico-politiche dell’Europa post-bellica, dopo la caduta dei regimi totalitari centrali ed il contestuale emergere, ad Oriente, del colosso sovietico-staliniano come alternativa al vittorioso costituzionalismo occidentale.
Questo volume si propone di ripercorrere il percorso intellettuale di un pensatore che ha interrogato il suo tempo consegnando alla posterità un lavoro imponente, che lo rende uno dei maggiori interpreti del totalitarismo sovietico e un teorico innovativo nella comprensione della democrazia.
Nel passaggio dall’antropologia alla storia, dalla filosofia alle scienze sociali, l’eredità lasciata dagli scritti di Claude Lefort possiede una ricchezza analitica tra le più profonde nell’alveo delle ricerche filosofiche dedicate alla modernità politica
Claude Lefort e a democracia selvagem
No full textIn this article, we will discuss and contextualize the notion of savage democracy within Claude Lefort\u27s democratic theory. The text will be divided into three parts. Firstly, we will present the fundamental ideas of the author\u27s political thought. Next, we will analyze the role of the notion of savage democracy in three texts by Lefort: two dedicated to the May 68 events, A desordem nova and Releitura as well as the preface to the second edition of the work Éléments d\u27une critique de la bureaucratie. Finally, we will present the recent discussion in Lefortian studies regarding the fertility of the term savage democracy mainly relating to two important themes for Lefort: the dimension of conflict in democracies and the relationship of law with democratic struggles.Neste artigo, discutiremos e contextualizaremos a noção de democracia selvagem dentro da teoria democrática de Claude Lefort.

Claude Lefort (1924-2010)
No full text Claude Lefort s´est éteint à Paris le 3 octobre 2010. Il laisse une œuvre importante et constitue l´un des grands penseurs politiques contemporains grâce à une trajectoire intellectuelle originale qui commença de notre point de vue en 1948 lorsqu´il fonda aux côtés de Cornélius Castoriadis le groupe Socialisme ou Barbarie. </p

Configurazioni del politico. Alterità e organicismo in Claude Lefort
No full textIn the aftermath of the Second World War the political duality between the sphere of influence of the Eastern and Western blocs, between two models of development and society, generated those anxieties that gave rise to consistent historical-philosophical theories on democracy and on the totalitarian vocation that characterized Soviet communism.
Claude Lefort gives us a primigenial analysis that, linked to the meaning of the social behaviors and their manifestation immanent to the political context, restores sensitivity to the historicity of our time, highlighting the deep dynamics that structure modern societies
Broad tuning around degeneracy in a singly resonant synchronously pumped parametric oscillator by means of a diffraction grating: Errata

Use of a diffraction-grating in a synchronously-pumped parametric oscillator for broad tuning around degeneracy
No full textPeriodically poled lithium niobate (PPLN) has, in recent years, become a very useful and prominent material for use in optical parametric oscillators (OPO's) and other nonlinear optical devices. In synchronously pumped OPO's, the combination of high peak power from short pulse cw modelocked lasers and the large nonlinearity of PPLN, allows a very large parametric gain to be achieved. This, in turn, allows the use of convenient tuning elements, such as diffraction gratings, whose loss would be unacceptable for low gain cw devices. The strong frequency discrimination, of diffraction gratings, allows operation close to degeneracy, while still maintaining singly resonant operation (SRO). The attraction of operating around degeneracy is that due to the large parametric gain bandwidth, a broad tuning range can be conveniently achieved, without the need to change the temperature or the grating period of the PPLN. The standard approach for achieving singly resonant operation, by using resonator mirrors whose reflectivity discriminates against the idler wave, precludes reliable operation around degeneracy due to insufficient frequency discrimination. The diffraction grating in place of one of the mirrors overcomes this problem. In this paper we report on results obtained by equipping a PPLN OPO, pumped by a 4ps, 120MHz Nd:YLF laser at 1047nm, with a diffraction grating as one of its reflectors. A 20mm long PPLN crystal, with a grating period of 30.4 µm, held at a fixed temperature of 190 °C, was used to obtain a tuning range of 1900 - 2300nm, simply by tilting the diffraction grating. Fig. 1 shows this tuning behaviour. The good beam quality of the signal is confirmed by a measured M2 of 1.16. A measurement of the spectral width and pulse duration (via extra-cavity SHG auto-correlation) gives a time-bandwidth-product of 0.46
