Abstract
A laser apparatus with a laser oscillator and a subsequently connected la intensifier which has an inlet region for the laser beam to be intensified coming from the laser oscillator and an outlet for the intensified laser beam and which is provided with a folding mirror that lies opposite to the inlet region for the laser beam to be intensified. The inlet region for the laser beam to be intensified is an opening in a further folding mirror which is located opposite to the other folding mirror. The outlet for the intensified laser beam likewise is an opening in one of the two folding mirrors. The opening width of the inlet opening and the outlet opening in relation to the mirror surface of the particular folding mirror is small. The cross section of the laser beam inside the laser intensifier is at least partially greater by a multiple than in the region of the inlet opening and outlet opening. In a region externally of the laser intensifier before respectively after the respective opening there is arranged a partially permeable respectively reflecting mirror so that the laser intensifier operates as a laser oscillator. The laser oscillator is integrated in the laser intensifier.
