Solar radiation may be converted directly into electricity by solar cells (photovoltaic cells). In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as
6 FAQs about [Is the high-speed laser light powered by solar energy ]
What is a solar pumped laser?
Solar-pumped lasers (SPLs), which convert sunlight into laser radiation, are of interest for applications, such as solar hydrogen generation, remote area telecommunications, space propulsion, space solar power systems, and high-efficiency photovoltaic energy conversion 1, 2, 3, 4, 5, 6, 7, 8.
Can sunlight be converted into laser light?
Broadband sunlight can be converted into laser light by solar pumping, which can be a source of narrowband, collimated, rapidly pulsed radiation—with the possibility of extremely high brightness and intensity.
Why are physicists using high-powered lasers?
Using high-powered lasers, physicists in Japan are doing the next best thing — for the briefest of instants they are creating similar conditions in the lab. The overall energy generated by those lasers is not especially impressive, but because it is highly compressed in time and space it creates mind-boggling power.
Are high-powered lasers a good idea?
High-powered lasers also have more down-to-earth applications. The most ambitious is researching laser fusion — using lasers to generate energy by merging light nuclei.
Could space-based laser power be a major step forward?
“Since solar energy is the most abundantly available and reliable power source in space, 10x more than on Earth, space-based laser power generation would be a major step forward in terms of fulfilling energy needs,” says Liang.
What can a solar laser be used for?
The team’s solar laser may find wide-ranging applications such as earth, ocean, and atmospheric sensing, laser beaming, deep space communications, and space debris removal.
