Technologies in High-Power Laser Diode Arrays.

Integrated Power Conditioning for Laser Diode Arrays

For several years, the Laser Program at LLNL has been designing and building a variety of specialized compact laser systems 1. They offer extremely high energy densities for their size and are primarily used in medical and military applications where a high premium is placed on both reliability and compactness. These systems are based upon a 2 cm-x-2 em liquid cooled wafer (Fig. 1) that support...

Photonic power delivery through optical fiber using very high power laser diode arrays

Described is a system that will provide isolated electric power for a circuit that drives the core reset of a pulsed power modulator. This can be accomplished by coupling light from a number of diode laser bars to bundles of 200 urn multimode optical fibers. This is then coupled to photo-voltaic power converters that will deliver 16 V 29 mA of electricity from 1 watt of optical power. Spot size...

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...

Risk Reduction and Advancement of High Power Quasi-CW Laser Diode Pump Arrays

The reliability of moderate to high power solid-state lasers that can operate autonomously over a sufficiently long period, are constrained by their laser diode pump arrays (LDAs). For laser remote sensing instruments operating in space, the reliability and lifetime of LDAs are particularly critical because of high development and launch cost of instruments and their inaccessibility in space. T...
