Femtosecond Time-Domain Measurements of Group Velocity Dispersion in AlGaAs Diode Lasers.

摘要

Femtosecond optical pulses are used to determine the round-trip propagation delay in AlGaAs diode lasers. By using pulses at different wavelengths, we have determined the dispersion in group index to be minus 2.9 per micrometer in these devices. Reprints. (rrh)
