Generating sets of tailored laser pulses

In a master oscillator power amplifier, a driver ( 208 ) of a diode laser ( 202 ) is specially controlled to generate a set of two or more injection laser pulses that are injected into a power amplifier ( 204 ) operated in an unsaturated state to generate a set ( 50 ) of laser pulses ( 52 ) that rep...

Zusammenfassung:	In a master oscillator power amplifier, a driver ( 208 ) of a diode laser ( 202 ) is specially controlled to generate a set of two or more injection laser pulses that are injected into a power amplifier ( 204 ) operated in an unsaturated state to generate a set ( 50 ) of laser pulses ( 52 ) that replicate the temporal power profile of the injection laser pulses to remove a conductive link ( 22 ) and/or its overlying passivation layer ( 44 ) in a memory or other IC chip. Each set ( 50 ) includes at least one specially tailored pulse ( 52 ) and/or two or more pulses ( 50 ) having different temporal power profiles. The duration of the set ( 50 ) is short enough to be treated as a single "pulse" by conventional positioning systems ( 380 ) to perform on-the-fly link removal without stopping.
