The Single shot autocorretation of femtosecond laser pulse width
and analysis of the results
ABSTRACT
This dissertation mainly discusses about the design work of single pulse system for femtosecond laser pulse width and analyzing the measurement the basis of the original measure system in the lab, we do the further optimization ,discuss the influence of optical elements in the system to the result of the measurement, designed and produced single pulse measuring system of femtosecond laser pulses. The main contents of this thesis are listed below:
1. The principles of femtosecond laser produce are single pulse measurement theoretical of femtosecond laser pulse width knowledge is knew;
2. The autocorrelation used in the single shot autocorrelation are design and constructed. We have been measuring the design of the system, choosing the instrument of the system, building missioning the system;
3. The single shot system design for measuring the pulse width of femtosecond lasers .Conclude the corresponding results, at the same time use the single shot autocorrelator (SSA) that has been produced to do the second measurement .Compare the two results of the measurement and evaluate the reliability of my own design system;
4. The result analyzing for measurement results is done. Conclude the corresponding femtosecond laser pulse width.
Key words: femtosecond laser, autocorrelation, Second harmonic(SH) ,single pulse measurement
