Special Issue Information

Dear Colleagues,

You are kindly invited to contribute to the Special Issue of Applied Sciences dedicated to pulsed fiber lasers and their applications. This Special Issue is aimed at collecting original research articles dedicated to scientific and technology innovations in all aspects of the development and application of pulsed fiber lasers. Review papers dedicated to the recent progress and important findings in the fundamental and applied research into pulsed fiber laser systems will be also appreciated.

Fiber lasers are known to be very flexible laser sources that offer a variety of possible pulsed lasing regimes with the unique adjustability of their parameters. Mode locking has been perhaps the most fruitful approach to obtaining pulsed output from fiber lasers so far. It provides a great number of options related to static and dynamic control over laser pulse shaping. Mode-locked fiber lasers are applied in many areas, owing to the unique properties of their radiation both in the time and frequency domains. A number of novel promising mode locking techniques have been introduced recently for fiber lasers. Besides mode locking, other effective methods of getting pulsed output from fiber lasers also remain of practical interest since they can provide some useful features. Continued development of photonic technologies and electronically controllable fiber components leads to the establishment of qualitatively new methods of electronic (and even smart) control over laser parameters in different types of pulsed fiber lasers.

Topics of the Special Issue interest include but are not limited to the following:

Novel architectures of pulsed fiber lasers, novel types of fiber-optics elements and fiber-optics devises intended for pulsed fiber lasers, novel physical aspects of pulse shaping and lasing dynamics in mode-locked fiber lasers (or in other types of fiber lasers with pulsed output), novel methods of static and dynamic control over lasing characteristics in mode-locked fiber lasers (or in other types of fiber lasers with pulsed output), novel applications of pulsed fiber lasers, or novel findings obtained with the instrumental aid of pulsed fiber lasers.

If in doubt, potential authors are encouraged to contact the Guest Editors with questions about the suitability of their research for the Special Issue prior to submission.

We present the results of ex vivo exposure by an ultrafast all-fiber Holmium laser system to porcine longissimus muscle tissues. A simple Ho-doped laser system generated ultrashort pulsed radiation with less than 1 ps pulse width and a repetition rate of 20 MHz at a central wavelength of 2.06 μm. Single-spot ex vivo experiments were performed at an average power of 0.3 W and different exposure times of 5, 30 and 60 s, varying the total applied energy in the range of 1.5–18 J. Evaluation of laser radiation exposure was performed according to the depth and diameter of coagulation zones, ablation craters and thermal damage zones during the morphological study. Exposure by ultrashort pulsed radiation with an average power of 0.3 W showed destructive changes in the muscle tissue after 5 s and nucleation of an ablative crater. The maximum ablation efficiency was about 28% at the ablation depth and diameter of 180 μm and 500 μm, respectively. The continuous-wave radiation impact at the same parameters resulted only in heating of the near-muscular tissue, without ablation and coagulation traces. Exposure to tissue with an average power at 0.3 W of ultrashort pulsed radiation led, within 30 and 60 s, to similar results as caused by 0.5 W of continuous-wave radiation, although with less carbonization formation.

Here we present a numerical study of pulsing build-up dynamics inside the fiber Mamyshev Oscillator (MO). The main scope of the investigation is to describe the influence of the spectral separation between the filters on self-starting MO dynamics and transition from multipulse to single-pulse generation regimes. It was found that Floquet stability analysis provides a straightforward way to determine whether the system will be self-starting or if it has to be excited by external source and predicts the repetition rate of the pulse train. We showed that spectrally overlapped bandpass filters provide reliable multi-pulse generation due to Faraday instability. Adiabatic increase in the spectral separation between the filters decreases the number of pulses down to single-pulse regime, therefore providing a flexible way to generate adjustable number of mode-locked pulses on demand.
