| Abstract: | The effect of the shape of the excitation pulses on the magnitude of the frequency chirp in an injection laser is investigated.
It is established that as the degree of rectangularity of the pulses becomes higher, the frequency chirp increases. Simultaneous
consideration of the effect of residual charge in the active region of the laser, the delay of stimulated radiation, and the
frequency chirp indicates that in the case of high-velocity code modulation of an injection laser, in the latter an irregular
frequency chirp appears that can exert a noticeable influence on the distortion of code trains of pulses having a super-Gaussian
shape, when they propagate in media with a dispersion of 100 p.s./nm/km and above.
