The invention relates to a gas discharge laser, in particular to a gas discharge laser with bipolar pulse power supply, which has applications in material processing, medicine, high-speed photography, etc. According to the invention, the gas discharge laser consists of a gas discharge laser tube with two electrodes, each electrode of the gas discharge laser tube being grounded via a capacitor. On the other hand, one of the electrodes is also connected to a switching system for positive pulses, and the other electrode is also connected to a switching system for negative pulses. The two switching systems represent and implement the bipolar pulse power supply of the gas discharge laser. Each of the switching systems has a switch. The switch can be gas discharge or semiconductor. The advantage of a gas discharge laser with bipolar pulse power supply is that the electrical power in the gas discharge laser tube is increased, while the potential to ground of the individual electrodes is less than 20 kV. In this gas discharge laser, the electrical energy switches operate at a pulse voltage of less than 10 kV and have a longer service life and greater reliability.
