Investigation Principles of Creation of Nanosecond Laser Driver with Operating Frequency up to 10 kHz

The aim of the work is to create a miniature pulse optical lidar on an infrared laser diode by means of highly effective avalanche switching in bipolar silicon transistors. Confident operation of the optical switch board at a frequency of 10 kHz with a dynamic charging circuit has been achieved. The ways of increasing the radiation power, increasing the repetition rate of pulses (necessary to improve the accuracy of the lidar) are considered.
