Abstract:
A laser apparatus for permanently removing a plurality of hair follicles from the skin of a patient, comprising:a) at least first and second lasers for sequentially emitting at least first and second pulses of coherent light energy each having a pulse width in the range of 1/2 ms to 10 ms; being a parametrically defined pulse group;b) optical delivery means connected to said at least first and second lasers for transmitting said at least first and second pulses of coherent light energy through an optical pathway to the same spot on the skin of a patient for removing hair follicles;c) means for controlling said at least first and second lasers to emit said at least first and second pulses of coherent light energy sequentially, with a time delay of less than 20 milliseconds between the sequential pulses from said at least first and second lasers; andd) a handpiece for holding a section of said optical pathway for directing said at least first and second pulses of coherent light energy to a selected spot of the patient's skin to remove the plurality of hair follicles.
