Abstract:
1. Apparatus for producing short optical pulses, comprising: an oscillator for producing optical pulses at a first optical pulse repetition frequency, the optical pulses having a first frequency of light; a pulse picker for receiving optical pulses having the first optical pulse repetition frequency and operable to reduce the optical pulse repetition frequency to produce optical pulses having the first frequency of light and a reduced optical pulse repetition frequency that is less than the first optical pulse repetition frequency; an optical fiber receiving optical pulses having the reduced optical pulse repetition frequency and first frequency of light, to nonlinearly produce light that includes a frequency of light that is twice the first frequency of light; an Ytterbium doped fiber amplifier in optical communication with said pulse picker and said optical fiber and located between the pulse picker and the oscillator; and a nonlinear optical crystal.
