“…Figure 3(a) shows the variation of the laser frequency, laser intensity and injection signal output intensity versus time. As has been stated by previous investigators, in lasers for which the relaxation oscillation exists and the detuning frequency is greater than the frequency of the relaxation oscillation, the frequency shift is negative [12,[33][34][35], which means that the laser frequency departs from the input signal frequency.…”

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.

“…In this regime the physical effect is primarily that of quenching of the free-running laser oscillation due to cross saturation. There have been some relatively recent works [19,20] emphasizing locking through cross saturation as opposed to synchronization, but these models do not include spatial hole burning, which we find to play an important role, and the models also involve many more approximations than our method, which is essentially an exact solution of the problem in the relevant regime.…”

We present an ab initio treatment of the steady-state of lasers with injected signals that describes a regime, valid for microlasers, in which the locking transition is dominated by cross saturation and spatial hole burning. The theory goes beyond standard approaches and treats multimode lasing with injected signals and finds the possibility of partially locked states and as well as repulsion of the free-running frequencies from the injected signal. The theory agrees well with exact integration of the full wave and matter equations for the system. It can also describe accurately complex modern lasers structures and is applied to the example of deformed disk lasers. We show that in the case of a one-dimensional cavity in the locked or regenerative amplifier regime the theory reduces to an improved version of the Adler equations in the appropriate limit.
