Abstract
An apparatus for seeding a solid-state, ultrashort optical pulse amplifier system comprises an excitation source that pumps a gain medium which is restricted to the core of an optical fiber. The gain medium is disposed in a resonant cavity with components arranged to produce ultrashort pulses of light at a fundamental wavelength. Such systems are well known to those skilled in the art. These ultrashort pulses are then frequency-doubled in a non-linear crystal to produce a seed pulse whose doubled frequency substantially matches that of the amplifier gain medium. These seed pulses are then injected into the amplifier wherein they are amplified.
