Spectroscopic Analysis of CdO1-X: SnX Plasma Produced by Nd:YAG Laser

Laser-produced MeV electrons and hard X-ray spectroscopic diagnostics

A new spectroscopic technique for the measurement of the sizes of hard X-ray sources produced by the irradiation of solid-density targets by intense laser radiation is discussed. The technique is based on the source broadening of K shell spectral lines from targets irradiated by intense picosecond laser pulses. The spectra are recorded by a modified Cauchois type spectrometer, where the detecto...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Brilliance Improvement of a Laser-Produced Soft X-Ray Plasma

The brilliance of a laser-produced soft X-ray source is enhanced for gaseous target concepts. In contrast to solid or liquid target materials, these sources are clean and versatile but provide a comparably low conversion efficiency of laser energy into EUV and soft X-ray radiation. The basic idea is to induce supersonic effects in the gas jet, leading to a local increase of the particle density...

Characterization of Expanding Laser Plasma Produced by Laser Ablation

This work is devoted to characterizing the plasma produced by nanosecond laser ablation. The expanding plasma was generated by the interaction of a home made XeCl excimer laser with a Cu target. The time-of-flight method was utilized as diagnostic tool of the plasma charged particles. By this method, in fact, we were able to measure the ion and electron currents, the charge-states and the energ...
