PHz scale spectral broadening and few-cycle compression of Yb:KGW laser pulses in a pressurized, gas-filled hollow-core fiber
We demonstrate efficient generation of coherent super-octave pulses via a single-stage spectral broadening of a Yb:KGW laser in a single, pressurized, Ne-filled, hollow-core fiber capillary. Emerging pulses spectrally spanning over more than \(\sim\)1 PHz (250 nm- 1600 nm) at a dynamic range of \(\s...

Summary: | We demonstrate efficient generation of coherent super-octave pulses via a single-stage spectral broadening of a Yb:KGW laser in a single, pressurized, Ne-filled, hollow-core fiber capillary. Emerging pulses spectrally spanning over more than \(\sim\)1 PHz (250 nm- 1600 nm) at a dynamic range of \(\sim\)60 dB, and an excellent beam quality open the door to combining Yb:KGW lasers with modern light field synthesis techniques. Compression of a fraction of the generated supercontinuum to intense (8 fs, \(\sim\)2.4 cycle, \(\sim\)650 \(\mu\)J) pulses allows convenient use of these novel laser sources in strong-field physics and attosecond science. |
