“…Injection of coherent radiation into a laser oscillator is known to affect seriously the nonlinear dynamics of a free-running oscillator, causing a large variety of effects which are of considerable interest from experimental as well as theoretical points of view [1][2][3][4][5][6], in particular in applications such as lidar ranging, selective photochemistry, laser induced plasma physics, optical logic gates and optical pumping. Injection locking represents an effective technique for stabilizing powerful laser oscillators which would otherwise have a highly unstable emission output.…”

In this paper, we present a theory for analysing the transient behaviour of injection-locked lasers with monochromatic injection, wherein homogeneously broadened wide-band lasers with injection are analysed. In addition to boundary conditions, the initial distribution of the laser and the monochromatic injection signal fields are necessary for solving the governing equations. The Maxwell–Bloch equations are reduced to a system of ordinary differential equations with the initial conditions. In this paper, two approximation methods are introduced. These approximations are named the De-satellite signal approximation and the finite number satellite signal approximation, respectively. The finite number satellite signal approximation is used to study the transient behaviour of the satellite signal around the laser frequency in injection-locked lasers. The results are in good agreement with the data published by the previous studies on this topic.

“…An important goal is the achievement of two-and multi-wavelength generation of nano-and subnanosecond pulses with implementation of our group's original methodology as well as development of multi wavelength generators of the same type based on semiconductor active media [Nenchev, 1995]. Our group has substantial expertise in the development of two-wavelength lasers [Deneva, 2010;Louyer, 2003;Slavov, 1998, Gorris-Neveux, 1995Nenchev, 1981]. Using our original approach we were the first in the world to develop with the corresponding theoretical and experimental background two-wavelength F-centers, Ti-Sapphire (in pulsed mode) and Yb:YAG lasers, (in a CW diode pumped mode) - [Loyer, 2003;Goris Neveux, 1995]).…”

The goal of the report is to present the development-principles, theories and computer simulations, experiments and practical realizations, of original and competitive methods, elements and devices for quantum electronics, optical communications, metrology, remote sensing and sciences: multi-channel WDM system with independent tuning of each input/output, multi-wavelength laser with independent control of each wavelength, lasers with emission, spectrally fixed at reference atomic absorption line, injection-locking laser system for high (~10 6-10 8) and linear amplification of low-power (~ µW, nW) modulated laser light, optical analogue of the transistor action-optical transistor, system for remote (up to kilometres) measurement of small (mm) translational elongation-shrinking of objects, new solution of tunable sub-nanosecond lasers and lasers with rectangular nanosecond (~1 ns) pulse emission, including controlled duration and tunable wavelength. The basic element of the devices developed is stable and compact interference wedged structures in new composite solution with very narrow transmission (≤ 0.01 nm) in relatively large spectral range (≥1 nm). The laser active media used are solid-state, semiconductor and dye.

Unidirectional ring TI3+:Al2O3 laser generation at the wavelength of an atomic absorption line by bidirectional passive self-injection locking

A simple, purely optical approach to produce, in a ring Ti:Al2O3 laser, a pulsed unidirectional generation, spectrally fixed at a reference atomic absorption line is described. The control relies on the unbalance between two opposite, passive, wavelength-scanned self-injections that is produced by the absorption at the reference line. It is shown both experimentally and theoretically that: (i) the emitted spectrum is centered at the absorption maximum and (ii) due to the nonlinear character of the process the spectrum is narrowed several times compared with an absorption linewidth.
