High performance semiconductor laser from Sharp

03.01.2013

Sharp has announced the release of a semiconductor laser GH0641FA2C with a wavelength of 642 nm and an efficiency of 33% - according to the manufacturer, a record for such devices. The laser is intended for use as a light source in compact projectors and car displays with image projection on the windshield.

The threshold current of the laser LED is 55 mA. With a typical operating voltage of 2,5 V and a current of 182 mA, the optical power is 150 mW. The horizontal and vertical divergence angles are 9° and 17°, respectively.

The manufacturer expects to start deliveries of trial samples of new lasers on January 31, 2013 at a price of about $58 per piece, and from March 29, 2013, serial production of GH0641FA2C in the amount of 10000 pieces per month should begin.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Honey anti aging 01.02.2008

Doctors from the University of the New Zealand city of Hamilton added 10% honey or 8% sugar to two groups of rats for a year, and the third group was not given any sweets.

It turned out that the rodents that received honey were the most courageous and curious - they were not afraid to go to the middle of the cage. In addition, they were better at remembering the correct path through a maze and were more likely to enter an unfamiliar maze. Doctors believe that honey consumption can improve memory and general mood in older adults.
