1. A high-energy laser system comprising:
- a seed laser constructed and arranged to output a sub-nanosecond pulsed laser beam;
an amplifier constructed and arranged to receive and amplify a sub-nanosecond pulsed laser light emitted by the seed laser;
a solid state pump laser constructed and arranged to deliver a pump laser beam to both the seed laser and the amplifier via at least one optical fiber; and
a variable attenuator configured to actively control time delay of Q-switched pulses to adjust pump beam energy for the seed laser to avoid missing Q-switched pulses,wherein the seed laser comprises;
at least a gain medium; and
a passive Q-switch.

8. A method of generating laser pulses comprising:
-
generating pulsed laser light using a seed laser comprising at least a gain medium and a passive Q-switch; directing the pulsed laser light to an amplifier; amplifying the pulsed laser light with the amplifier; and operating a pump laser to provide pumping energy to both the seed laser and the amplifier; and operating a variable attenuator to actively control time delay of Q-switched pulses to adjust pump beam energy for the seed laser to avoid missing Q-switched pulses. - View Dependent Claims (9, 10, 11, 12)
