Abstract:
1. A method for generating pulsed laser energy, the method comprising: (a) 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 polarizing element and a three terminal Pockels cell within said resonator with the three terminal Pockels cell having a first drive circuit connected to a first end of the Pockels cell and a second drive circuit connected to a second end of the Pockels cell and generating a modelocked pulse within the resonator by the first circuit applying a periodic voltage waveform to the first end of the Pockels cell; and (b) then amplifying the modelocked pulse by the first circuit applying a first constant voltage to the first end of the Pockels cell and maintaining an effective reflectivity of the second mirror at substantially 100%; and (c) then extracting the amplified modelocked pulse from the resonator by the second circuit applying a second constant voltage to the second end of the Pockels cell and maintaining an effective reflectivity of the second mirror at substantially 0%.
