A dual wavelength scanning spectrophotometric method for the analysis of small absorbance changes in turbid suspensions is presented, which improves upon the point by point method of obtaining difference spectra in terms both of accuracy and rapidity. Examples are shown of the application of this in
Problems are discussed which occur during the normal usage of these dual-wavelength, solit-beam instruments which can cause serious errors in the derived data and which, when rkognized, can be avoided.
## Abstract All optical wavelength conversion between picosecond pulses based on fourβwave mixing (FWM) is experimentally demonstrated in 80βm dispersionβflatted high nonlinear microstructure fibers (MF). The pulsed signal with 10βGHz repetition rate and 1.6βps pulse width is used as pump wave. In
