Efficient single-cycle pulse compression of an ytterbium fiber laser at 10 MHz repetition rate

Abstract: Over the past years, ultrafast lasers with average powers in the 100 W range have become a mature technology, with a multitude of applications in science and technology. Nonlinear temporal compression of these lasers to few-or even single-cycle duration is often essential, yet still hard to achieve, in particular at high repetition rates. Here we report a two-stage system for compressing pulses from a 1030 nm ytterbium fiber laser to single-cycle durations with 5 μJ output pulse energy at 9.6 MHz repetition ra… Show more

“…There has been little focus on the noise properties, except for a recent work reporting good long-term stability, but high pulse-to-pulse RIN values of 33.3% of a 275 nm RDW, attributed to the large RIN of 5.5% of the 2.45 µm pump 25 . The technology is now maturing to a level ready for applications, such as imaging and spectroscopy, which has seen a recent push towards table-top ytterbium-based lasers with MHz repetition rates as pump lasers, giving few-hundred fs pulses at center wavelengths of 1030 nm 21 , 22 . To get the necessary short pump pulses external pulse compression with chirped mirrors and a second gas-filled HC fiber is used the generate < 30 fs pump pulses 21 , 22 .…”

With the push towards MHz and applications it has become even more important to assure low levels of RIN of the source and one could fear that the external pulse compression module could significantly add to the RIN of an otherwise low-noise seed laser.…”
