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 Reliability of High Power and High Brightness Diode Lasers
We report on continued progress in the development of high power and high brightness single emitter laser diodes from 790 nm to 980 nm for reliable use in industrial and pumping applications. High performance has been demonstrated in nLIGHT’s diode laser technology in this spectral range with corresponding peak electrical-to-optical power conversion efficiency of ~65%. These pumps have been inc...
متن کاملAdvances in high brightness semiconductor lasers
We review recent advances in high power semiconductor lasers including increased spectral brightness, increased spatial brightness, and reduced cost architectures at wavelengths from the near infrared to the eye-safe regime. Data are presented which demonstrate both edge emitter devices and high power surface emitting 2-dimensional arrays with internal gratings to narrow and stabilize the spect...
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 کاملHigh-brightness lasers on silicon by beam combining
High-brightness lasers are widely used in fields such as spectroscopy, infrared countermeasures, free-space communication, and industrial manufacturing. Integration of a broad-band, multi-spectral laser is made possible by heterogeneously integrating multiple gain materials on one silicon (Si) substrate chip. A single multi-spectral output with high beam quality can be achieved by wavelength be...
