Combination of a highly efficient Yb-doped fibre and glass-air waveguide for multi-point pump injection allows to reduce device length to less than 3 m %B Summaries of papers presented at the Conference on Lasers and Electro-Optics: Baltimore Convention Center, Baltimore, Maryland, May 23 - 28, 1999 %T Single clad coiled optical fibre for high power lasers and amplifiers %C Washington, DC, US %D 1999 %P CPD26/1 - CPD26/2
