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. Solar pumped lasers might become useful in off-grid locations. Very fine grained 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

There are different types of optical sensors, but in general, they all consist of a light source (usually an LED or a laser), a light receiver, and a signal processing circuit. When the light emitted by the light source is blocked or reflected by an object, the light receptor detects the change and generates an electrical signal indicating the presence or …
