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 کاملCharacterization of High-Power Lasers
This paper discusses methods for characterization of high power lasers. Specifically, these methods have been developed for the High Energy Laser Joint Technology Office and used for independent, government-sponsored testing in the 25 and 100 kW phases of the Joint High Power Solid State Laser program. Primarily this paper addresses measurement of power and beam quality.
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 کاملWelding with High Power Diode Lasers
Laser welding with CO2, fiber and various types of solidstate lasers is a well established process currently utilized in a wide range of industries and applications. However, recent technological developments in high power diode laser technology have expanded the capabilities of laser welding, as well as changed its cost characteristics. As a result, diode lasers are poised to replace tradition...
