Title: Photorefractive Response Time Measurement In Gaas Crystals By Phase Modulation In Two-wave Mixing
Author: Bian Shaoping
Frejlich Jaime
Abstract: The possibility of using phase-modulation techniques in two-wave mixing (2 WM) experiments for response time measurement in fast materials such as GaAs is shown in the study. The main idea here is that a small phase modulation in one of the interfering beams makes the interference pattern on the crystal vibrate with the modulation frequency. The modulation technique described here is similar to that reported for photoelectromotive-force measurement in photoconductors.
