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