METHODS AND APPARATUS PERTAINING TO PICOSECOND PULSED FIBER BASED LASERS
A pulse conditioning apparatus can comprise a signal splitter for splitting a pulsed input signal into first and second pulsed signals; a spectrally dispersive element configured for subjecting the first pulsed signal to a spectral dispersion for compressing or stretching the first pulsed signal, th...

| description | A pulse conditioning apparatus can comprise a signal splitter for splitting a pulsed input signal into first and second pulsed signals; a spectrally dispersive element configured for subjecting the first pulsed signal to a spectral dispersion for compressing or stretching the first pulsed signal, the first and second pulsed signals being subjected to substantially different spectral dispersion; and a combiner for combining the first and second pulsed signals to an output pulsed signal, the output pulsed signal output comprising pulses having a surge pulse portion and a base pulse portion, at least one of the portions derived at least in part from the spectral dispersion and attendant compression or stretching of the first pulsed signal. |
