摘要

The results of theoretical and experimental investigations of the influence of air pressure on the dimensional and power parameters of preliminary focused GW femtosecond laser radiation are presented. A nonlinear region of the focus of a laser beam is examined. It is established that in rarefied air the achievement of higher values of laser radiation intensity in the focal waist is possible due to a decrease in the plasma block-ing action.

Home > All Content > Vol 50, No 1 (2019) Exploring Research–Policy Partnerships in International Development Cover Page Edited by: James Georgalakis and Pauline Rose June 2019 Volume 50 Issue 1 This issue aims to identify how partnerships focused on the production of policy-engaged research seek to achieve societal impact and explores the challenges in these processes. The collaborations analysed span academia, civil society and government, from the grassroots to the national and global levels. By locating these examples within the broader debates on interactions between researchers and research users designed to strengthen evidence informed decision making, this publication offers concepts and practices to inform those funding, designing and undertaking development research. The featured case studies are explored through the perspectives of both researchers and their partners in civil society and policy. They are predominantly taken from a diverse portfolio of research projects funded through the UK’s Economic and Social Research Council (ESRC) and the Department for International Development (DFID) Strategic Partnership. A collaboration with the Impact Initiative, this IDS Bulletin is essential reading for all those in research organisations, development agencies and donors committed to the better use of evidence and learning for development.
