Abstract
Apparatus for producing short optical pulses comprising an oscillator for producing optical pulses at a first optical pulse frequency, the optical pulses having a first wavelength; first and second optical amplifiers; a pulse picker, located between the first and second optical fiber amplifiers, the pulse picker operable to reduce the optical pulse frequency of optical pulses, the amplifier amplifying optical pulses at the first optical pulse frequency and the second amplifier amplifying optical pulses at a reduced optical pulse frequency that is less than said first optical pulse frequency; and a nonlinear optical fiber receiving amplified optical pulses at the reduced optical pulse frequency and having the first wavelength to nonlinearly produce, at the reduced optical pulse frequency, optical pulses that include a wavelength that is different than the first wavelength.
