On the way to the ideal lithotripsy laser

A description is presented of a way to the ideal lithotripsy laser including the problem of an ideal application system to minimize secondary effects to the patient. The study summarizes the advantages and disadvantages of already established laser systems in terms of physical and clinical aspects. Furthermore it presents an optical feedback regulation system to avoid adverse tissue effects. Finally, an active Q-switched Alexandrite laser is presented as an ideal LISL-system.
