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 کاملPassively Q-switched ceramic Nd3+:YAG/Cr4+:YAG lasers.
Passively Q-switched ceramic Nd3+:YAG lasers with ceramic Cr4+:YAG saturable absorbers are demonstrated. When the lasers are pumped by a 1-W cw laser diode, optical-optical efficiency as great as 22% is obtained with Cr4+:YAG of initial transmission ranging from 94% to 79%. The results are similar to those in their crystalline counterparts. The operation of Brewster's angle and the polarization...
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).
متن کاملFaraday Isolators for High Average Power Lasers
The average power of solid-state and fiber lasers has considerably increased during the last ten years. The 10 kW power is not record-breaking any longer, and a topical problem nowadays is to create lasers with a power of 100 kW. Therefore, the study of thermal effects caused by absorption of laser radiation in the bulk of optical elements becomes ever more important. The Faraday isolator (FI) ...
