Stabilization of a Harmonic Mode-Locking by Shifting the Carrier Frequency

Birth and Annihilation of Solitons in Harmonically Mode-Locked Fiber Laser Cavity Through Continuous Wave Injection

“…4 (a); the angle α is inversely proportional to the soliton velocity change at the moment of new soliton birth. This observation can be explained recalling the gain depletion and recovery mechanism that provides soliton repulsion inside the cavity [17,18]. As a result, the birth of new soliton is accompanied by redistribution of accumulated energy among all solitons.…”

Supermode noise mitigation and repetition rate control in a harmonic mode-locked fiber laser implemented through the pulse train interaction with co-lased CW radiation

“…Generally, its value is much higher than that of mode locked lasers operating at the fundamental frequency [1,2]. Therefore, physical mechanisms enabling jitter reduction in HML fiber lasers are of great practical importance [3][4][5][6][7][8][9]. The role of background radiation as a mediator providing the equalizing interaction between pulses has been extensively discussed in this context [10][11][12].…”

Soliton Raman shift wavelength tuning through the pump pulse polarization control

“…Due to a wide range of applications, design of laser sources of extended telecom range is among hot topics of modern laser physics [1][2][3][4][5]. In addition to the well-known problem related to the growing demands in telecom fiber optical data transmission systems of extended bandwidth in recent years the researchers developed an interest to the mode-locked lasers of 1600-1700 nm spectral range for a number of biomedical applications [6][7][8][9][10].…”

“…Laser sources operating at the wavelengths over 1.8 μm is of particular interest for applications in LIDARs, spectroscopy, and atmospheric analysis [11][12][13][14]. Passively mode-locked fiber lasers combining high beam quality, simplicity of adjustment, reliability, user-friendly fiber interface and relatively low cost are of great demand for these applications [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”
