“…For high frequencies, the RIN of the laser and the PM-HNLF approach the system noise floor: above ∼200 kHz, the laser and the PM-HNLF show shot-noise-limited per- formance at approximately −150 dBc, which is lower than reported for a low-noise fiber laser [42]. The single peak of the PM-HNLF at 1.6 MHz is probably caused by an insufficient shielding of the detection system.…”

We report measurement of the first carrier-envelope offset (CEO) frequency signal from a spectrally broadened ultrafast solid-state laser oscillator operating in the 1.5 µm spectral region. The f -to-2f CEO frequency beat signal is 49 dB above the noise floor (100-kHz resolution bandwidth) and the free-running linewidth of 3.6 kHz is significantly better than typically obtained by ultrafast fiber laser systems. We used a SESAM mode-locked Er:Yb:glass laser generating 170-fs pulses at a 75 MHz pulse repetition rate with 110-mW average power. It is pumped by one standard telecom-grade 980-nm diode consuming less than 1.5 W of electrical power. Without any further pulse compression and amplification, a coherent octave-spanning frequency comb is generated in a polarization-maintaining highly-nonlinear fiber (PM-HNLF). The fiber length was optimized to yield a strong CEO frequency beat signal between the outer Raman soliton and the spectral peak of the dispersive wave within the supercontinuum. The polarizationmaintaining property of the supercontinuum fiber was crucial; comparable octave-spanning supercontinua from two non-PM fibers showed higher intensity noise and poor coherence. A stable CEO-beat was observed even with pulse durations above 200 fs. Achieving a strong CEO frequency signal from relatively long pulses with moderate power levels substantially relaxes the demands on the driving laser,

“…For the timing-detector method, we used a home-built 200-MHz soliton Er-fiber laser [29] as a reference laser, and used the phase detection at 1.4 GHz (the 7th harmonic) for locking the repetition rate of the two lasers with 1-kHz bandwidth. For the timing-delay method, a 325-m-long dispersion-compensated fiber link is used.…”

“…Examples are mechanical vibrations, the coupling of intensity noise to timing noise through finite gain bandwidth, and the coupling of center frequency fluctuations to timing noise through intra-cavity dispersion. Several recent timing jitter measurements of various types of free-running passively mode-locked Er-fiber lasers have shown $10-to 30-fs timing jitter level when integrated from 10 kHz to 10 MHz [28][29][30]. Although these are impressive results when compared to most commercially available, high-quality microwave oscillators, there is still much room for improvements in timing noise by carefully suppressing 'technical' noise sources in the pulse generation processes to reach the predicted attosecond-jitter performance.…”

We review our recent progress toward attosecondprecision ultrafast photonics based on ultra-low timing jitter optical pulse trains from mode-locked lasers. In femtosecond mode-locked lasers, the concentration of a large number of photons in an extremely short pulse duration enables the scaling of timing jitter into the attosecond regime. To characterize such jitter levels, we developed new attosecond-resolution measurement techniques and show that standard fiber lasers can achieve sub-fs high-frequency jitter. By leveraging the ultralow jitter of free-running mode-locked lasers, we pursued highprecision optical-optical and optical-microwave synchronization techniques. Optical signals spanning 1.5 octaves were synthesized by attosecond-precision timing and phase synchronization of two independent mode-locked lasers. High-stability microwave signals were also synthesized from mode-locked lasers with drift-free sub-10-fs precision. We further demonstrated the attosecond-precision distribution of optical pulse trains to remote locations via timing-stabilized fiber links. Finally, the application of optical pulse trains for high-resolution sampling and analog-to-digital conversion is discussed.The ultra-low timing jitter of optical pulse trains from femtosecond mode-locked lasers can be used for the attosecond-precision generation, distribution, measurement, and synchronization of optical and microwave signals.

“…In some examples two full polarization con− trollers are used (one before and one after polarization beam splitter) [18], in some setups proper position of the fibre guarantees that mode−locking will be obtained with only one PC (placed before PBS) [19]. Other examples include two [20], three [21] or four [22] wave plates. However, the biggest challenge is not the number of wave plates but the mechanism of their adjustment.…”

In this paper we present a novel configuration of an NPR mode-locked Er-doped laser. This new optical setup uses voltage controlled LC cells to replace standard retarders (quarter-and half-waveplates) inside the laser cavity. Using this novel, mechanical-adjustment-free setup a mode-locking was obtained with sub-500 fs pulse duration and an average power exceeding 40 mW. Presented results show that using simple LC cells, an optical layout of an NPR mode-locked laser can be greatly simplified.
