High-Power High-Brightness Lasers
High power high brightness diode lasers are gaining more and more interest for applications previously dominated by expensive and inefficient solid-state lasers due to their better efficiency, brightness and compactness. The significant fact about conventional high brightness optical sources is that they exhibit about an order of magnitude higher brightness than broad-area semiconductor lasers....
متن کاملHigh power ultrafast lasers
In this article, we review progress in the development of high peak-power ultrafast lasers, and discuss in detail the design issues which determine the performance of these systems. Presently, lasers capable of generating terawatt peak powers with unprecedented short pulse duration can now be built on a single optical table in a small-scale laboratory, while large-scale lasers can generate peak...
متن کاملAdvantages of KrF Lasers for Inertial Confinement Fusion Energy
Advanced concepts for direct drive inertial confinement fusion (ICF) have emerged that may lead to sufficient gain for the energy application (g>140) at laser driver energies as low as 1 megajoule. For example, recent “shock ignition” designs compress low aspect ratio pellets then apply a final high intensity spike pulse (10 16 W/cm 2 ) to ignite the fuel via a converging shock wave. These anal...

متن کاملProposal for high-power radiative-collisional lasers.
We propose the use of the radiative-collisional laser process for the extraction of energy that is stored in the resonance lines of the alkali atoms. The largest calculated gain occurs in Rb at 5.4 microm and is 8%/cm at a resonance-line population of 5 x 10(16) atoms/cm(3).
