EDFA-based ultrashort optical pulse amplification and its developments

This paper describes the principle and defect of measuring the shape and chirp of the ultrashort optical pulse by means of intensity autocorrelation and interferometric autocorrelation,and proposes a theory and an apparatus for directly measuring the amplitude and phase spectra.

By using distributed feed back laser diode and gain switching technology the characteristicsof ultrashort optical pulses under different conditions are studied.

The principle to measure S parameters of microwave devices with ultrashort optical pulses has been described.

Generation of ultrashort optical pulses from semiconductor lasers by strong current modulation is discussed theoretically and some experimental results of ultrashort optical pulse generation from semiconductor lasers by microwave strong modulation are explained.

It is a key problem to detect the ultrashort pulse in optical communication system.

By using KTP nonlinear crystal as extracavity frequency doubling and combining stimulated Raman scattered (SRS) technique in a CPM unstable resonator Nd∶YAG laser, the ultrashort pulses at three different wavelengths of 1.

The constant carrier lifetime assumption in the time dependent rate equations, which is used to study the dynamic response of semiconductor optical amplifier to ultra short optical pulse, has been modified, and a treatment method about the carrier lifetime is presented.
