Abstract: A laser system may include one or more seed lasers to generate a pulsed seed beam. The system may further include a pulse pattern generator to generate an intermediate patterned burst-mode beam from at least one laser pulse from the pulsed seed beam, where the intermediate patterned burst-mode beam includes one or more pulse bursts, and where each of the one or more pulse bursts includes a series of laser pulses with a selected pattern of inter-pulse spacings. The system may further include two or more power amplifiers to amplify the intermediate patterned burst-mode beam to form an amplified patterned burst-mode beam, where at least two of the power amplifiers amplify different portions of the intermediate patterned burst-mode beam, and where the amplified patterned burst-mode beam includes a series of amplified pulse bursts including amplified laser pulses with the selected pattern of inter-pulse spacings.

Abstract: A laser system may include one or more seed lasers to generate a pulsed seed beam including one or more laser pulses, a pulse pattern generator to generate an intermediate patterned burst-mode beam from at least one laser pulse from the pulsed seed beam, where the pulse pattern generator includes splits the at least one laser pulse from the pulsed seed beam along two or more delay paths and combines light along the two or more delay paths to a common optical path, and where the intermediate patterned burst-mode beam includes laser pulses with a selected pattern of inter-pulse spacings associated with the two or more delay paths. The laser system may further include power amplifiers to amplify the intermediate patterned burst-mode beam to form an amplified patterned burst-mode beam, where the amplified patterned burst-mode beam includes amplified laser pulses with the selected pattern of inter-pulse spacings.
