Abstract
A MOPA laser system that includes a seed laser configured to output pulsed laser light, an amplifier configured to receive and amplify the pulsed laser light emitted by the seed laser; and a pump laser configured to deliver a pump laser beam to both the seed laser and the amplifier.
Claims18
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;
- and
- 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,
- wherein to generate sub-nanosecond pulses, a resonator of the seed laser is made short by bonding a saturable absorber to a laser rod, and depositing resonator mirrors directly on to the end surfaces of laser rod and saturable absorber assembly.
