emittance control in high power linacs

چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...

High-Power Green Laser Sources

To access the green spectral range for display applications, high-power optically pumped semiconductor disk lasers (OPSDLs) in combination with second-harmonic generation have been realized. A frequency-doubled output exceeding 9.5W is achieved at a wavelength of 520 nm. The wavelength of these devices can be tuned over a rather broad range of more than 20 nm in the second-harmonic regime. In t...

High-power high-repetition-rate single-mode Er-Yb-doped fiber laser system.

We demonstrate an all-fiber-integrated, high-power chirped-pulse-amplification system operating at 1550 nm. The seed source is a soliton fiber laser with 156 MHz repetition rate. Two-stage single mode amplifier provides an amplification of more than 40 dB without significant spontaneous amplified emission. The power amplifier is based on cladding-pumped 10 µm-core Er-Yb co-doped fiber, the outp...

High-efficiency, single-stage 7-kHz high-average-power ultrafast laser system.

We demonstrate a simple and practical single-stage ultrafast laser amplifier system that operates at a repetition frequency from 1 to 10 kHz, with millijoule pulse energy and as much as 13 W of average power. The repetition rate can be adjusted continuously from 1 to 10 kHz by new all-solid-state pump laser technology. This is to our knowledge the highest average power ever obtained from a sing...
