At least while making the flow form approximately 50000 the pulse which possesses with the pulse rate of pulse per second and the length around the pulse which is shorter than as many as 1 picoseconds, for example in order to make operation complete during time of several seconds, at least many pulse using 100000 pulses during brief than as many as 10 seconds, for example surgical operation disposal (, scanning the output optical pattern which is suited) for the organization cutting for ophthalmology, it is the device and the method of featuring that it makes the aforementioned flow focus. Regarding the execution form of part, dispersion of negative number in order to adjust beforehand is generated, the correct dispersion the said dispersion in the scan system is compensated. In addition, using the laser and the scan system regarding the execution form of part, it cuts off the minute lens, in order for the said lens to pass the cornea surface, it is removed mechanically through the side section slit which was formed.< Selective figure > Figure 1少なくとも約50000パルス/秒のパルス繰り返し数と1ピコ秒よりも短いパルスあたりの長さとを有するパルスの流れを生成させ、数秒程度の時間内に手術を完了させるために、少なくとも多数のパルスたとえば10秒よりも短い時間内に100000パルスを使用して、外科手術処置(たとえば、眼科の)のための組織切断に適した出力光パターンを走査しながら、前記流れを集束させることを特徴とする装置と方法である。一部の実施形態においては、あらかじめ調節するための負の分散を発生させ、該分散が走査システムにおける正の分散を補償する。また、一部の実施形態においては、レーザーおよび走査システムを使用して微小レンズを切断し、該レンズが角膜表面を通過するように形成された側部スリットを通して機械的に取り出される。【選択図】 図1
