We have developed chirped volume Bragg grating compact pulse compressors and robustly single-mode large-core fibers using chirally-coupled-core (CCC) structures, recently demonstrating high average power and 200 fs FCPA based on these new components. A combination of these two technologies is becoming an enabler for finally achieving trully compact high power ultrashort-pulse lasers.
Record-short pulses of 200 fs have been obtained from a power-scalable-Yb-fiber-CPA system that uses chirped-volume-Bragg-gratings for the stretcher and compressor. The power was scaled up to 50 W with a corresponding 33 W of compressed power.
Femtosecond (~670 fs) fiber-CPA at 1.063 mum is demonstrated using broadband chirped-volume-Bragg-gratings for pulse stretching and compression. 32 W recompressed pulses are achieved corresponding to a 75% compression efficiency.
50-W average power fiber-CPA at 1055-nm is demonstrated using chirped- volume-Bragg-gratings for pulse stretching and compression. This compact pulse compression technology is efficient (83% compression efficiency in the current demonstration) and suitable for further power scaling.
