“…Ref. [46] demonstrates compression of the entire pulse and its shortest part from 6.26 ps and 227 fs down to 690 fs and 59.6 fs correspondingly. The shortest compressed sub-pulse (14.5 fs) within a noise-like pulse was demonstrated in [47].…”

“…Of course, the question was raised of the possibility of temporal compression of noise-like pulses. The general answer is that it is possible, but not down to record-breaking levels [46]. Additionally, it is problematic to isolate the shortest pulse from the noise-like train, because the position of this pulse within the envelope and its amplitude are unpredictable.…”

The report considers prospects of development, on the basis of fibre lasers, of an 'incoherent laser' producing noise-like pulses. The possibility is demonstrated of a radically new radiation source occupying, in terms of output properties, an intermediate place between incandescent bulb and laser. Combination in such a laser of high output beam directivity, brightness and incoherent character of the radiation is quite important in many applications where speckle patterns of the light field are an undesirable effect.

“…Some time ago, research was undertaken in order to find out whether noise-like pulses might have giant chirp [26] and their compression might be possible [40]. It was established that sub-pulses of noise-like pulses do not have giant chirp and, therefore, noise-like pulses are not amenable to significant compression [41].…”

Approaches to the development of an incoherent laser are analysed. Implementation of such a laser on the basis of noise-like pulse generation is discussed. Fairly high stability of the average output power in such a regime leads to the contemplation of practical avenues to developing an incoherent laser relying on noise-like pulses. Implementation of such a laser on the basis of the fibre-optical platform further poses such requirements as all-fibre design using polarisation-maintaining fibre and adoption of alternatives to material-based saturable absorbers. Applications are demonstrated in which an incoherent laser—a radically new source of optical radiation—is a requirement. Laser layouts are shown, which are close to the desired layout of the incoherent laser.

“…Therefore, considering the limited gain bandwidth, most few-cycle techniques focus on high-power, highenergy lasers and nonlinear pulse compression systems. Noise like mode-locked lasers have the potential to output high-energy pulses [9] . The nonlinear media include multiplates, multipass cells, and gas-filled hollow core fibers that are based on selfphase modulation (SPM) [10][11][12][13] .…”

Generation of sub-three-cycle pulses at 53 MHz repetition rate via nonlinear compression in optical parametric oscillator

We report an experimental generation of few-cycle pulses at 53 MHz repetition rate. Femtosecond pulses with pulse duration of 181 fs are firstly generated from an optical parametric oscillator (OPO). Then, the pulses are compressed to subthree-cycle with a hybrid compressor composed of a commercial single-mode fiber and a pair of prisms, taking advantage of the tunability of the OPO and the numerical simulating of the nonlinear compression system. Our compressed optical pulses possess an ultrabroadband spectrum covering over 470 nm bandwidth (at −10 dB), and the output intensity fluctuation of our system is less than 0.8%. These results show that our system can effectively generate few-cycle pulses at a repetition rate of tens of megahertz with excellent long-term stability, which could benefit future possible applications.
