11–18 GHz continuously tunable repetition rate picosecond laser source at 1030 nm

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 [2, 3]. Only few developments exist so far at the Ytterbium gain window around 1 μm, where power scaling towards high average power and high energy level is obvious. In this talk, we will report on the development of a picosecond laser system operating at 1030 nm with a continuously tunable repetition rate from 11 to 18 GHz at a W-level average power.
