Definitions
- the invention relates to a short-pulse laser, in particular for generating laser pulses in the ps range for use in industrial and scientific environment.
- the invention is concerned with the desire for a compact design of the laser while maintaining high efficiency.

- all optical components necessary for generating the short laser pulses including a seed laser oscillator, a post-amplifier chain and a pulse picker, are mechanically stably mounted on an optical disk.
- a water cooling and a costly temperature stabilization are used.
- a structure in free-beam optics requires a relatively large amount of space. The necessary water cooling and temperature stabilization bring comparatively high operating costs.
- a construction in fiber technology is problematic because of the occurrence of nonlinear optical effects. Without a stretcher-compressor combination, the desired short pulse durations can not be achieved with sufficient pulse energy.
