Journal ArticleDOI
Diode-pumped gigahertz femtosecond Yb:KGW laser with a peak power of 3.9 kW
S. Pekarek,C. Fiebig,M. C. Stumpf,Andreas Oehler,Katrin Paschke,Götz Erbert,Thomas Südmeyer,Ursula Keller +7 more
TL;DR: This Yb:KGW laser has a high potential for stable frequency comb generation and could increase the pulse repetition rate up to 4 GHz with an average power of 900 mW and a pulse duration of 290 fs.
Journal ArticleDOI
Self-referenceable frequency comb from a gigahertz diode-pumped solid-state laser
TL;DR: It is demonstrated that pulse compression towards lower soliton orders of approximately 10 was required for coherent SC generation and CEO detection, and coherent supercontinuum (SC) generation in a highly nonlinear photonic crystal fiber (PCF) is achieved without additional amplification.
Journal ArticleDOI
Self-referencable frequency comb from a 170-fs, 1.5-μm solid-state laser oscillator
TL;DR: In this paper, the first carrier-envelope offset (CEO) signal from a spectrally broadened ultrafast solid-state laser oscillator operating in the 1.5 μm spectral region is reported.
Journal ArticleDOI
Fully stabilized optical frequency comb with sub-radian CEO phase noise from a SESAM-modelocked 1.5-µm solid-state laser
Stéphane Schilt,Nikola Bucalovic,Vladimir Dolgovskiy,C. Schori,M. C. Stumpf,Gianni Di Domenico,S. Pekarek,Andreas Oehler,Thomas Südmeyer,Ursula Keller,Pierre Thomann +10 more
TL;DR: The fractional frequency stability of the CEO-beat is 20‑fold better than measured in a standard self-referenced commercial fiber comb system and contributes only 10(-15) to the optical carrier frequency instability at 1 s averaging time.
Journal ArticleDOI
Femtosecond diode-pumped solid-state laser with a repetition rate of 4.8 GHz.
S. Pekarek,Alexander Klenner,Thomas Südmeyer,C. Fiebig,Katrin Paschke,Götz Erbert,Ursula Keller +6 more
TL;DR: A diode-pumped Yb:KGW (ytterbium-doped potassium gadolinium tungstate) laser with a repetition rate of 4.8 GHz and a pulse duration of 396 fs is reported, which is the femtosecond DPSSL with the highest repetition rate ever reported so far.
