METHOD FOR GENERATING GIGAHERTZ BURSTS OF PULSES AND LASER APPARATUS THEREOF

摘要

Method for generating gigahertz bursts of laser pulses is provided, where: 1) time delay T2 of the delayed part with respect to the undelayed part of the input pulse is longer than a time period T1 between said input pulse and the next input pulse; 2) said bursts of output pulses have an incrementally increasing number of pulses; 3) intra-burst pulse separation inside the formed bursts is equal to T3 = T2 – T1 and corresponds to an ultra-high pulse repetition rate higher than 100MHz. In another embodiment: 1) T2 is longer than M*T1, where M = 2, 3, etc.; 2) output train of bursts is composed of bursts of pulses wherein M adjacent bursts have identical number of pulses; 3) T3 is equal to T3 = T2 – M*T1. The laser apparatus for implementing the method is provided.
