LIGHT SOURCE WITH PRECISELY CONTROLLED WAVELENGTH-CONVERTED AVERAGE POWER

摘要

Control of average wavelength-converted power or pulse energy is described. Seed pulses may be generated, amplified and wavelength converted. Wavelength-converted power or pulse energy may be controlled by adjusting conversion efficiency without substantially changing amplified power or pulse energy. Average wavelength-converted power may be controlled over a time comparable to an amplified pulse period without adjusting average amplified pulse power over that time. An optical system may comprise a seed source coupled to an optical amplifier, a wavelength converter coupled to the optical amplifier, and a controller coupled to the seed source, optical amplifier or wavelength converter. The controller may control average wavelength-converted power over a time comparable to an amplified pulse period without adjusting average amplified pulse power over that time. Alternatively, the controller may control wavelength-converted pulse energy by adjusting conversion efficiency without substantially changing amplified pulse energy.
