Abstract (en)
[origin: WO8707165A1] A laser system is capable of producing a plasma in a target irrespective of whether the target (18) is absorbing or non-absorbing for the laser pulses. This system is particularly useful for making precise cuts in animal tissue for laser surgery such as for opthamological procedures. The system including a generation zone (24) for generating a principal lasing radiation pulse (44), an shortening zone (56) for shortening the duration of the principal pulse, a pulse multiplier (102) that multiplies the shortened pulse to a plurality of temporally, and preferably spatially, spaced apart pulses, and a beam delivery system (28) that focuses the spaced apart pulses into a sufficiently small spot size to achieve an irradiance of at least about 10<13> watts/cm<2> in the target. A pulse shortener achieves substantial pulse shortening using amplified spontaneous emission.
