摘要: A pulse multiplier includes a polarizing beam splitter, a wave plate, and a set of multi-surface reflecting components (e.g., one or more etalons and one or more mirrors). The polarizing beam splitter passes input laser pulses through the wave plate to the multi-surface reflecting components, which reflect portions of each input laser pulse back through the wave plate to the polarizing beam splitter. The polarizing beam splitter reflects each reflected portion to form an output of the pulse multiplier. The multi-surface reflecting components are configured such that the output pulses exiting the pulse multiplier have an output repetition pulse frequency rate that is at least double the input repetition pulse frequency.
