飞秒激光细丝与宽带压电换能器超声诊断的新机会被认为是。横向空间分辨率优于100微米，表明在单一和定期多个平行度制度，使路径向三维灯丝断层扫描。圆柱声源的简单解析模型与实验数据吻合较好。
New opportunities in ultrasound diagnostics of femtosecond laser filaments with wideband piezoelectric transducers are considered. Transverse spatial resolution better than 100 microns is demonstrated in the single and regular multiple filamentation regime making path toward 3D filament tomography. The simple analytical model of the cylindrical acoustic source fitted well with the experimental data.
