It is shown that for reliable operation of laser diode matrices, it is important to ensure a maximum permissible, but not leading to their destruction, current input and output rate. Some solutions used in constructing laser diode drivers for the purpose of limiting the rate of rise during the introduction and removal of a current are presented. A method for controlling the rate of rise of a laser emitter current is presented which essentially involves forming the leading and trailing edges of the output current of the laser driver so that its first and, at least, second derivative were continuous in order to avoid triggering internal mechanisms that lead to degradation of the emitter structure.
