Open the CIPO recordAbstract From the Canadian patent
A laser amplifier operable such that at the commencement of each output pulse the carrier level has recovered from depletion by the previous pulse. Under these conditions output power commensurate with a much high carier density than is usually available is possible. The mode of operation is especially useful as a way of providing high power pulses for example for use in optical time demain reflectometry. Using a travelling wave amplifier in conjunction with return to zero formate data pulses is also disclosed.
