“…On the other hand, for technical reasons the mechanical vibrations of the cavity length tend to be larger for long cavities. This effect together with the difficulty of measuring very weak timing noise is the reason why quantumlimited timing jitter performance [11,27,32,33] is more easily seen for compact laser cavities with relatively high losses, where quantum noise influences are relatively strong while classical noise inputs can be effectively minimized.…”

This work present a comprehensive discussion of the noise properties of mode-locked lasers, with an emphasis on the effect of quantum noise in passively mode-locked solid-state lasers. Of special interest is the timing jitter, which is coupled to noise in various other pulse parameters. The study is based on analytical results and on numerical tools as described in part one of this study. It results in useful guidelines for the comparison and optimization of different kinds of lasers concerning timing jitter.PACS 43.50.+y, 42.50.Lc, 42.60.Fc

“…Therefore, even without an ultrastable cavity, ultrafast laser itself can serve as an ultralow-jitter signal source when the laser noise performance is optimized toward the quantum limit. The timing jitter spectrum of mode-locked Ti:sapphire lasers was measured already in the early 1990s, which resulted in the integrated rms jitter ranging from several hundreds fs to a few ps range, depending on the laser condition, measured offset frequency range, and measurement methods 13,14 . With the rapid advancements of ultrafast mode-locked solid-state and fiber lasers, laser stabilization methods and noise measurement techniques in the last 20 years, ~10 fs-level high-frequency timing jitter/phase noise can be routinely demonstrated from different types of free-running, passively mode-locked solid-state and fiber lasers in recent years 15,16,17,18 .…”

Progress in ultrafast fiber lasers for ultralow-jitter signal sources

We introduce the most recent progress in the optimization of ultrafast fiber lasers for building ultralow timing jitter signal sources. Using a sub-20-attosecond-resolution timing jitter measurement technique, we optimize the timing jitter of optical pulse trains from mode-locked Er-fiber and Yb-fiber lasers to 70 attoseconds and 175 attoseconds, respectively, when integrated from 10 kHz to 40 MHz offset frequency. To our knowledge, these results correspond to the lowest rms timing jitter demonstrated from fiber lasers so far, the equivalent phase noise of which is comparable to that of the best microwave sources available, with much reduced cost and engineering complexity.

“…Pulsed optical fields, such as those generated by mode-locked lasers, do not exist in this idealised limit and the relevant noise properties have been studied through measurements of the pulse energy on a photodiode [2][3][4][5][6]. Theoretical and experimental studies of photodiode radio-frequency signals produced by short laser pulses in the picosecond [7] and femtosecond regime [8][9][10][11][12] provide detailed information about stochastic pulse train perturbations, including timing jitter, amplitude perturbations, and pulse width fluctuations. More recently, the role of the carrier-envelope offset phase noise in spectral-comb line broadening with mode-locked few-cycle lasers has been recognised, characterised, and controlled [13][14][15][16].…”
