Self-pumped phase conjugation in cerium-doped barium titanate crystal using nanosecond pulses from a laser diode
Abstract:Self-pumped phase conjugation was performed in a photorefractive cerium-doped barium titanate crystal by nanosecond pulses from a laser diode. The reflectivity of the phase conjugator against the incident angle and the incident position was measured in two configurations. The steady-starte reflectivity of the pulsed phase-conjugate wave increases and the response time decreases as pulse width of incident pulses increases.
