We report the development of a neodymium:yttrium aluminum garnet regenerative ring amplifier seeded by multiple pulse injection. This method of injection allows us to avoid the difficulties and expense of low-power, single-pulse selection. We observed output energy up to 0.6 mJ/pulse (±5% fluctuation). A saturable absorber in the cavity allowed compression down to 55 ps.
