Abstract: A sub-nanosecond laser system is disclosed. The sub-nanosecond laser system may include: a pump laser source operable to generate a pump laser beam having a pump wavelength; a first pump beam splitter operable to receive the pump laser beam and split the pump laser beam into at least a first split pump laser beam and a second split pump laser beam; a passively Q-switched seed laser operable to receive the first split pump laser beam and generate a seed laser beam; and an amplifier assembly operable to receive the second split pump laser beam and the seed laser beam. The amplifier assembly may include one or more amplifiers arranged in series in a multi-stage configuration, arranged in a multi-pass configuration, or a combination thereof.
