Abstract:
1. A fiber Chirped Pulse Amplification (CPA) laser system, comprising: a seed laser configured to produce a first laser pulse having a first pulse width; a fiber-based stretcher configured to receive the first laser pulse and output a second laser pulse having a second pulse width wider than the first pulse width, wherein the fiber-based stretcher comprises a hollow core configured to guide the first laser pulse and a plurality of holes surrounding the hollow core, wherein the plurality of holes have substantially the same width; and a solid-core fiber component configured to simultaneously amplify and compress the second laser pulse to output a third laser pulse having a third pulse width shorter than the second pulse width, wherein the seed laser is configured to output a laser with power lower than 10 mW, wherein the solid-core fiber component is configured to output a laser with power higher than 2 W.
