Laser-ultrasonic temperature mapping of an acousto-optic dispersive delay line

Autor: Alexander I. Chizhikov, Elena B. Cherepetskaya, Vladimir Ya. Molchanov, Oleg Yu. Makarov, Vasily Zarubin, S. A. Tretiakov, Konstantin B. Yushkov, Alexander A. Karabutov, A. I. Kolesnikov

Publikováno v: NDT & E International. 98:171-176

Many acousto-optic paratellurite-based devices use a slow shear bulk wave for interaction with light beams. Strong bulk absorption of this wave leads to a significant inhomogeneous crystal heating, a drift of material constants, and to the consequent

Linear Phase Design of Piezoelectric Transducers for Acousto-Optic Dispersion Delay Lines Using Differential Evolution for Matching Circuit Optimization

Autor: Alexander I. Chizhikov, Vladimir Ya. Molchanov, Konstantin B. Yushkov, Oleg Yu. Makarov

Publikováno v: IEEE transactions on ultrasonics, ferroelectrics, and frequency control. 67(5)

A numerical method for providing linear phase response of bulk acoustic wave (BAW) piezoelectric transducers (PTs) of acousto-optic devices is developed. Our approach is based on the analytic approximation of the phase response of the PT with the mat

Acousto-optical delay lines for femtosecond pulse shaping based on crystal materials with strong acoustic anisotropy

Autor: Vladimir Ya. Molchanov, S I Chizhikov, Oleg Yu. Makarov, Vladislav Ginzburg, Efim A. Khazanov

Publikováno v: SPIE Proceedings.

The femtosecond pulse quality in a laser system is determined by a non-compensated high-order dispersion and spectral deformation of the amplifier. A dispersive device that modifies the spectral amplitude and phase of the femtosecond pulse should be
