Abstract
Apparatus and methods for anisotropic pumping of a Kerr lens modelocked laser. Direct diode laser pumping of an ultrafast Kerr lens modelocked laser oscillator is accomplished. Diode lasers generate severely anisotropic beams, meaning the pump beam has a higher-beam-quality dimension and a lower-beam-quality dimension. By spatially overlap of the pump beam higher-beam-quality dimension and the KLM laser mode, KLM operation is accomplished. Multiple laser diode pump beams are combined in counterpropagating and same-side configurations.
