Abstract :
We have developed a nonlinear spectrophotometer that can measure nondegenerate spectra from 1.7 μm in the IR to 200 nm in the UV. Dual diode arrays for the IR and visible are used to measure the spectral changes in the transmittance against a reference beam. The pump beam is the output of a regeneratively amplified, frequency doubled, femtosecond fiber ring oscillator
