A special interferometric technique with high sensitivity has been devised on the basis of rainbows refractometer without the use of an additional and delicate amplitude-splitting setup. This new technique was use for the characterization of shock wave plasma induced by a Q-sw Nd-YAG laser on various kinds of metal samples...

Baground: the optimal management of lower calyceal stones is still controversial, because no single method is suitable for the removal of all lower calyceal stones. Minimally invasive procedures such as extracorporeal shock wave lithotrispy (ESWL), percutaneous nephrolithotomy (PNCL) and flexible ureteroscopy (fURS) are the therapautic methods for lower calyceal stones....

In spite of abundant experimental evidences supporting the viability of the laser induced shock wave plasma model for the explanation of the important features ofthe plasma and the associated spectroscopic characteristics, a controversy on the atomic excitation mechanism in the plasma has remained to be completely resolved. In this study...

This book presents a wealth of images of shock wave phenomena, gathered by the author over the past 40 years. Shadowgrams and interferograms of basic shock-dynamic topics such as reflection, diffraction, refraction, and focusing of shock waves in gases and liquids are sequentially displayed. Though the images themselves are self-explanatory,...

ABSTRACT
An comprehensiove study has been carried out for the study and extension of lases induce shock wave plasma spectroscopy (LISPS) application to non metalic soft and hard samples. For this purpose, a series of experiments were conducted to investigate the dynamical process taking place in the laser plasma generated by...

Laser Nd-YAG dengan energi 26 mj dan 53 mj, lebar pulsa 8ns di/Okla/can ke target (Cu) pada tekanan udara yang dikurangi. Peningkatan rasio sinyal latar belakang (S/B) dimungkinkan dengan kombinasi unik dari plasma yang dibatasi (confined plasma) dan teknik pencitraan (imaging technique). Dengan menggunakan teknik pencitraan, plasma primer (primary plasma)...

ABSTRAK
Telah dilakukan penelitian efek penguapan selektif (selective vaporation) plasma gelombang kejut (shock wave plasma) yang dibangkitkan dengan memfokuskan iradiasi laser TEA CO2 (130 mJ, 100 ns) atau laser Nd-YAG (50mJ, 8ns) pada bahan kuningan yang memiliki kandungan Zn (seng) dan Cu (tembaga) dalam udara tekanan rendah (1 Torr). Efek penguapan...
