Abstract
A system for the measurement of high bandwidth peak power pulses from laser sources. A laser pulse from a laser is directed onto the surface of a diffuser that replicates the pulse. A linear array of fiber optics of varying fiber length transmits the replicated pulses to a detector. The detector produces n pulses having a pulse width .lambda., each separated in time by a given time delay .DELTA.t which is directly proportioned to the length of each fiber. The output of the detector is fed to a digitizing oscilloscope to produce of digitized average pulse phase output.
Claims5
A system for measuring the peak power of pulses from a laser source comprising:
- a source of laser pulses, means responsive to at least one laser pulse to replicate said at least one pulse n times to provide n pulses;
- a plurality of n optical fibers connected to said means to replicate for separately transmitting each one of said n pulses wherein said n optical fibers are of varying length by an amount .DELTA.L from L-l to L-n, said means for detecting each of said n pulses to produce a sequence of pulses separated in time by .DELTA.t wherein .DELTA.t is directly proportional to Al.
