Passively harmonic mode-locking has been experimentally demonstrated in an erbium-doped fiber laser with large normal dispersion using single-multi-single mode structure as artificial saturable absorber. By increasing the pump power under the same polarization setting, the mode-locking operation can switch from fundamental mode-locked to 5th order harmonic mode-locked. Highest repetition rate of 4.26 MHz (5th order harmonic) is observed, with pulse width and pulse energy ascertained at 290 fs and 3.0 nJ, respectively. Excellent signal-to-noise ratio (SNR) of above 50 dB is observed for all harmonic orders. The findings validated that SMS structure can be used to generate stable and switchable high order of harmonic mode-locked. The low-cost SMS fiber for harmonic mode-locked generation technique could lay the groundwork for future sustainable industrial growth.

With the development of laser technology, microstructured optical fibers (MOFs) have become an important part of ultrafast optics, providing excellent platforms for ultrafast laser pulse generation, amplification, and compression, promoting the development of fiber laser systems to generate high power, high pulse energy, and few-cycle duration pulses. MOFs extend the ultrafast laser spectrum to the vacuum ultraviolet (VUV) and even extreme ultraviolet (EUV) regions based on dispersive wave emission and high harmonic generation, as well as to the mid-infrared region based on soliton self-frequency shift (SSFS), contributing compact and low-cost light sources for precision microscopy and spectroscopy. In this paper, first several common types of MOFs are introduced, then the various applications of MOFs in ultrafast optics are discussed, mainly focusing on the aspects of ultrafast laser pulse scaling in pulse energy and spectral bandwidth, and finally the possible prospects of MOFs are given.

“…These fields and the models' applications are considered as the main motivation for focusing of many researchers in different science branches on finding the exact, semi-analytical, and approximate solutions of them that show more hidden characterizations in the phase shift of the interaction between fast and slow solitons in the collision between two solitary waves [19,20]. Therefore, many accurate computational techniques have been derived, such as the Khater method, modified Khater method, generalized Khater method, Khater II method, sine-Gordon method, Kudryashov method, tanh-method, sech-tanh method, Riccati expansion method, direct algebraic method, and so on [21,22,23,24]. However, the search for a more accurate and general technique is still moving on as there is no unified method that can be applied to all nonlinear evolution equations [25].…”

This paper examines the soliton phase shift using a simplified third-order generalized nonlinear Schrodinger equation (3-order GNLSE). In this investigation, we employ a new direct algebraic (NDA) technique to solve these models. All evaluated solutions are put to the test using two modern numerical (trigonometric quantic and cubic B-spline) schemes. The necessary criteria for implementing numerical systems are derived from the computational solutions. As the model captures the dynamical behavior of ultra-short pulses in optical fiber and quantum fields, this research is crucial. As a wave model, the 3-order GNLSE equation may be used to illustrate the wave nature of matter. It is regarded as a quantum-mechanical state function since it may represent the dynamical and physical behavior of atoms and transistors. The exactness of the answers is shown through two-dimensional, three-dimensional, and contour charts (matching between analytical and numerical solutions). The answers presented in the research are innovative in comparison to earlier findings.AMS classification: 35C08; 37K40; 35C07; 37K40.
