Abstract: Method for processing of material by use of a pulsed laser, comprising generating a series of ultra-short laser pulses (22 ), directing each laser pulse (22) to the material with defined reference to a respectively assigned processing point (26) of a processing path (25), and focussing each laser pulse (22) so that respective focal points of the focussed laser pulses (22) comprise pre-defined spatial relations to a first surface (2) of the material, wherein each emitted laser pulse (22) effects a respective crack (24) within the material. According to the invention, each laser pulse is shaped regarding its beam profile so that a cross sectional area, which is defined by a cross section of the laser pulse in its focal point orthogonal to its propagation direction, is of particular shape and has a main extension axis (A) of greater extend than its minor extension axis. One major crack (24) is effected by each laser pulse (22), the major crack (12, 24) having a lateral extension basically oriented according to the main extension axis (A) of the respective pulse in the focal point. Furthermore, each laser pulse (22) is emitted so that the orientation of its main extension axis (A) in the focal point corresponds to a pre-defined orientation relative to an orientation of a respective tangent to the processing path (25) at the assigned processing point (26).

Abstract: A laser comprising a standing wave resonator comprises a first resonator section (26), which has the first end mirror (24, 24') and, if appropriate, others of the optical elements (32, 40), which interact with the laser beam between the first end mirror (24, 24') and the laser medium (23) and a second resonator section (27), which has the second end mirror (25) and others of the optical elements (36 - 39), which interact with the laser beam between the laser medium (23) and the second end mirror (25). At least one of the optical elements (24, 40) of the first resonator section (26) is embodied in focusing fashion. As a result, the beam axes (30, 30') of the laser beam which arrives upon respective tiltings of at least one of the optical elements (25, 36-39) arranged in the second resonator section (27) have at least one crossing point (31). Said crossing point (31) or one of said crossing points (31) of the beam axes (30, 30') of the laser beam lies in the pump region of the laser medium (23) or is at a distance from the pump region which amounts to less than the Rayleigh length. The radius (w) of the laser beam, at least over the section of the laser beam which lies between the laser medium (23) and the closest focusing element (24, 40) of the first resonator section (26), is less than five times, preferably less than three times, the radius (w) of the laser beam in the pump region of the laser medium (23).
