1. A method for treating a skin pigmentation, the method comprising generating pulsed laser energy bya) reflecting laser energy generated by a lasing medium between a first mirror at one end of a resonator and a second mirror at the opposite end of said resonator and through a polarizer and one or additional electro-optical devices within said resonator and generating a modelocked pulse within the resonator by applying a periodic voltage waveform to the one or additional electro-optical devices;

  • and(b) then amplifying the modelocked pulse by applying to said one or additional electro-optical devices a first constant voltage and maintaining an effective reflectivity of the second mirror at substantially 100%; and

    (c) then extracting the amplified modelocked pulse from the resonator, and exposing pigmented skin of a patient to the pulsed laser energy.
