  • Fiber-MOPA apparatus for delivering pulses on demand
    Patent number: 8717670
    Abstract: A fiber-MOPA includes a seed-pulse source followed by fiber amplifier stages. The seed pulse source delivers signal pulses for performing a laser operation and delivers radiation between the seed pulses to maintain the collective average of the seed pulse power and intermediate radiation power constant. Keeping this average power constant keeps the instantaneous available gain of the fiber amplifier stages constant. This provides that the seed pulse delivery can be changed from one regime to a next without a period of instability between the regimes.
    Type: Grant

    Date of Patent: May 6, 2014
    Assignee: Coherent, Inc.
