PDF | In this dissertation are reported technological advancements in solar-pumped lasers and solar energy collection and concentration systems.
Solar-pumped lasers are not used commercially because the low cost of electricity in most locations means that other more efficient types of lasers that run on electrical power can be more economically used. However, solar-pumped lasers might become useful in off-grid locations. Very fine dispersed powders can be produced by the use of laser synthesis technology. A leader in this field is Shigeaki Uchida and his team in Japan (Tokyo/Osaka). Their design uses Fresnel lenses
In electrically driven lasers, the solar energy is initially converted into electricity, and then electrical energy is fed into the laser to generate the coherent beam.
Germanium laser power converters—devices that convert laser light into electrical power via the photovoltaic effect—offer attractive cost advantages, particularly at 1550 nm, a wavelength
Solar-pumped laser A solar-pumped laser (or solar-powered laser) is a laser that shares the same optical properties as conventional lasers such as emitting a beam consisting of coherent
