Resonant holographic interferometry with ZnTe:V:Mn.
The photorefractive semiconductor ZnTe:V:Mn is investigated for use in real-time resonant holographic interferometry applications. Experimental results of two-wave and four-wave mixing with pulsed dye and cw diode lasers are presented; in addition holographic image transfer, as well as two-wavelength resonant holographic interferometry, are demonstrated. Species-specific interferograms of potassium seeded into various combustion environments are captured at video-frame rates. Calculations of the species measurement sensitivity and dynamic range are presented, and design considerations for resonant holographic interferometry systems employing photorefractive materials are outlined.
