Abstract

The paper presents a model of a free space optical transmitter operating in the wavelength range of 8-12 μm. In the transmitter, a quantum cascade laser controlled by a special driver was applied. The driver provides the control of the energy, repetition rate and duration of radiation pulses. In the described transmitter, generation of pulses with high duty cycle is also provided, making it possible to use the data link with either RZ or NRZ coding. In the frame of the study, the impact of laser working conditions on the data link operation was determined.
