Pulse shaping module and generator for use with a pulsed laser oscillator

摘要

A digital pulse shaping module provides a digital waveform such as a pulse shape, gating or a synchronizing digital signal for use with a pulsed laser oscillator. The digital pulse shaping module includes a waveform data generator that generates N-bit words having a number N of bits. A serializer is further provided to receive the N-bit words from the waveform data generator and outputs each bit individually in a series of bits corresponding to the digital waveform. The digital pulse shaping module further includes a delay module that provides a fine delay in the outputting of the bits by the serializer. This fine delay corresponds to a number of bits smaller than N, impacting on the timing of the outputted signal at the bit level. A pulse shaping generator has a plurality of digital pulse shaping modules.

1. A digital pulse shaping module for providing a digital waveform for use with a pulsed laser oscillator, comprising:
a waveform data generator for generating at least one N-bit word having a number N of bits, said at least one N-bit word being representative of said digital waveform; a serialiser receiving said at least one N-bit word and outputting each bit thereof individually in a series of bits corresponding to the digital waveform; and a delay module providing a fine delay in the outputting of the bits of said series by the serialiser corresponding to a number of bits smaller than N, the delay module being coupled to the waveform data generator to provide a value for the fine delay to said waveform data generator, the waveform data generator incorporating a number of zero bits in said at least one N-bit word according to said value for the fine delay.
