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 replicate the...

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.
