Instruments of optical pulse characterization |
摘要 |
An optical transmission system is provided by preparing a two-photon transition medium where efficiency of two-photon transition does not depend on polarization; splitting an optical pulse to be measured into a probe optical pulse and a gate optical pulse by a polarization independent beam splitter; after adding variable delay time to this gate optical pulse, entering the probe optical pulse and the gate optical pulse into a highly efficient two-photon absorption medium so that both of the pulses cross each other, and thereby generating an optical gate function; resolving a spectrum of the transmitted probe optical pulse, and detecting the spectrum by a photodetector; and measuring intensity of electric-field absorption of the probe optical pulse as a function of delay time and a frequency.
