Picosecond Yb-doped fiber laser source with a repetition rate continuously tunable between 11 and 18 GHz

Summary form only given. Electro-optical combs generated from continuous-wave sources through amplitude and phase modulations have the potential to generate picosecond pulses with multi-GHz tunable repetition rates. They find applications in polarized Gamma ray production [1], imaging and picosecond acoustics. However, the development of such combs is mainly carried out with 1.5 μm laser sources [1, 2]. Only few developments exist so far in the Ytterbium gain window around 1 μm, where power scaling towards high average power and high energy is obvious. In this talk, we will report on the development of a picosecond (one) laser system operating at 1030 nm with a continuously tunable repetition rate between 11 and 18 GHz at the W-level average power.
