title: Influence of amplified spontaneous emission on gain lifetime in high-aperture Ti:sapphire amplifiers.
abstract: We demonstrate that by lowering gain lifetime, transverse amplified spontaneous emission imposes practical limit on usable aspect ratio of large-aperture amplifiers in a high-energy Ti:sapphire system.
