Abstract: The invention relates to a short-pulse laser device (11) with a preferably passive mode coupling. Said device comprises a resonator (12) which contains a laser crystal (14) in addition to several mirrors (M1-M7, OC) that define a long resonator arm (17) and a short resonator arm (16), one (M1) of said mirrors forming a pump beam coupling-in mirror and another (OC) forming a laser beam output coupler and comprising a multiple reflection telescope (18) that increases the length of the resonator and is allocated to the resonator arms (16, 17). Said telescope is constructed using mirrors (25, 26), in order to reflect a laser beam (15) that is coupled into the space between them back and forth several times, prior to being decoupled back into the other resonator, whereby sequential eccentric reflection points (1 to 8; 1? to 8?) on the mirrors (25,26) are offset in relation to one another.
