Patent ID: 8665918

Claim:
A system for providing high power, wavelength tunable, laser radiation, the system comprising: a plurality of seeder sources, each said source of said plurality having a different fixed seeder wavelength; a seeder driver for selectively and independently activating a plurality of selected seeder sources in said plurality of seeder sources; a Ytterbium doped amplifier chain, receiving radiation from each said selected seeder in said plurality of seeder sources and at least one pump source thereby amplifying radiation from each of said plurality of selected seeder sources; a second harmonic generator communicating with said Ytterbium doped amplifier chain, said second harmonic generator comprising converting radiation of each said different seeder wavelength into radiation of a respective second harmonic wavelength; and wherein said second harmonic generator comprises a crystal having a plurality of grating segments, each grating segment in said plurality of grating segments being a discrete poling region, wherein each grating segment converts radiation of a specific and different said seeder wavelength; optical parametric oscillator of fixed uniform polling spacing driven by said radiation of a second harmonic wavelength and wherein said system is configured to accept laser radiation from more than one said seeder source at a time.
