“…The FPGA circuit is triggered by the RF signal derived from the optical pulse train produced by the oscillator signal. This low-jitter signal [32] is low-pass filtered to retain only the fundamental frequency of 100 MHz, which is used as the internal clock signal of the FPGA, ensuring the tightest possible synchronization allowed with the hardware limitations of an FPGA. The FPGA, in turn, triggers three arbitrary waveform generators (AWG), one of which drives the AOM and the other two provides pulses to diode drivers, which are capable of pulsed operation.…”

Ultrafast lasers operating at high repetition rates, in particular the GHz range, enable new possibilities in lasermaterial processing, particularly accessing the recently demonstrated ablation-cooled regime. We provide a unified perspective of the unique opportunities created by operating at high repetition rates together with our efforts into the development of enabling laser technology, including new results on further scaling up the capabilities of the laser systems. In order to access GHz repetition rates and microjoule-level pulse energies without requiring kilowatts of average power, we implement burst-mode operation. Our results can be grouped into two distinct directions: low-and highpower systems. Pulsed pumping is employed in the later stages of low-power systems, which have low burst repetition rates to achieve high pulse energies, whereas the technique of doping management is developed for the continuously pumped power amplifier stage of high power systems. While most of the developments have been at 1-µm wavelength range due to the relative maturity of the laser technology, we also report the development of Tm-fiber lasers around the 2-µm region specifically for tissue processing and laser-surgery applications.

“…A fundamental advantage of this new reference is that it provides the possibility for temporal diagnostics based on mixing optical signals, which is inherently more precise than mixing electronic signals. Laser oscillators also exhibit superior short-term stability 33 34 , although they must still be cross-referenced to an electronic oscillator to maintain medium-term stability and to prevent long-term drifts 35 .…”

Femtosecond all-optical synchronization of an X-ray free-electron laser

Many advanced applications of X-ray free-electron lasers require pulse durations and time resolutions of only a few femtoseconds. To generate these pulses and to apply them in time-resolved experiments, synchronization techniques that can simultaneously lock all independent components, including all accelerator modules and all external optical lasers, to better than the delivered free-electron laser pulse duration, are needed. Here we achieve all-optical synchronization at the soft X-ray free-electron laser FLASH and demonstrate facility-wide timing to better than 30 fs r.m.s. for 90 fs X-ray photon pulses. Crucially, our analysis indicates that the performance of this optical synchronization is limited primarily by the free-electron laser pulse duration, and should naturally scale to the sub-10 femtosecond level with shorter X-ray pulses.

“…For example, a fiber comb is proposed to be used in advanced accelerators for precise timing control of electron bunches. 35) The Ti:S and fiber combs completely cover a wavelength range from 500 to 2000 nm. For wavelengths shorter than 500 nm, one possible approach is to use the broadened spectrum obtained by injecting the second-harmonic generation (SHG) of a mode-locked fiber laser into a PCF.…”

The precision measurement of time and frequency is of great interest for a wide range of applications, including fundamental science and technologies that support broadband communication networks and the navigation with global positioning systems (GPSs). The development of optical frequency measurement based on frequency combs has revolutionized the field of frequency metrology, especially research on optical frequency standards. The proposal and realization of the optical lattice clock have further stimulated studies in the field of optical frequency metrology. Optical carrier transfer using optical fibers has been used to disseminate optical frequencies or compare two optical clocks without degrading their stability and accuracy. In this paper, we review the state-of-the-art development of optical frequency combs, standards, and transfer techniques with emphasis on optical lattice clocks. We address recent results achieved at the University of Tokyo and the National Metrology Institute of Japan in respect of frequency metrology with Sr and Yb optical lattice clocks.
