Fiber Lasers of Prof. Okhotnikov: Review of the Main Achievements and Breakthrough Technologies

Parabolic pulse generation in short fiber amplifiers

“…For a real fiber amplifier of length L, the optimization could be performed not only by a proper choice of parameters in equation (3) determining the pulse | | A . 2 Varying the initial values of ( ) t 0 p and ( ) u 0 0 within a certain range, we could determine a parabolic pulse described by equation (6) (evolving in an amplifier with a spectrally flat saturated gain) that corresponds to the minimal MF parameter.…”

“…The technology of pulsed fiber lasers and amplifiers is currently in demand for a wide range of applications: optical communication, material processing, medicine, etc [1,2]. Urgent industrial needs in fiber systems delivering pulses of higher energy, peak power, and shorter pulse duration stimulate elaboration of new approaches to amplification and generation of laser pulses.…”

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].…”

Fine tuning of the repetition rate and stabilization of harmonically mode-locked fiber laser with CW component in the spectrum

“…Ultra-fast laser sources delivering pulses with the pulse repetition rate (PRR) in sub-GHz and GHz ranges are of great interest for many applications in spectroscopy, microwave photonics, ranging sensing, telecommunications, etc. [1][2][3][4][5][6][7][8][9][10][11][12]. 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.…”
