The possibility of controlling laser generation in a layered structure using a nematic liquid crystal (NLC) is theoretically studied. This structure consists of a thin layer of silver (Ag), a layer of NLC doped with a light-absorbing dye, and a distributed Bragg reflector (DBR). The spectral dependencies of the reflection, transmission, and absorption coefficients of light by such a structure, as well as the enhancement coefficient of the light field in the NLC layer in the DBR's band gap, are calculated. The narrow dips in the reflection coefficient and the peaks in the transmission coefficient are caused by the excitation of Tamm plasmon-polaritons (TPPs) at the Ag-NLC interface. The excitation of TPPs is accompanied by a significant increase in the intensity of the light field in the NLC volume compared to the intensity of the incident light. With an increase in the thickness of the NLC, the density of Tamm-plasmon peaks increases. It is shown that in the case of an optical anisotropy 𝛥𝑛=𝑛𝑒−𝑛𝑜=0.3, the control range for the position of the plasmon peaks reaches up to 100nm. Temporal luminescence pulses for pump pulses of different power settings are also presented. Above threshold, luminescence in the system manifests itself in the form of a series of short pulses with their amplitude and duration monotonically decreasing over time. Increases in the peak power of the pump cause the duration of the individual luminescence pulses to decrease.
