Carbon-dioxide laserThe carbon-dioxide laser (CO2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964 and is still one of the most useful types of laser. Carbon-dioxide lasers are the highest-power continuous-wave lasers that are currently available. They are also quite efficient: the ratio of output power to pump power can be as large as 20%. The CO2 laser produces a beam of infrared light with the principal wavelength bands centering on 9.6 and 10.6 micrometers (μm).
Optical fiberAn optical fiber, or optical fibre in Commonwealth English, is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables.
Black-figure potteryBlack-figure pottery painting, also known as the black-figure style or black-figure ceramic (), is one of the styles of painting on antique Greek vases. It was especially common between the 7th and 5th centuries BCE, although there are specimens dating as late as the 2nd century BCE. Stylistically it can be distinguished from the preceding orientalizing period and the subsequent red-figure pottery style. Figures and ornaments were painted on the body of the vessel using shapes and colors reminiscent of silhouettes.
Red-figure potteryRed-figure vase painting is one of the most important styles of figural Greek vase painting. It developed in Athens around 520 BCE and remained in use until the late 3rd century BCE. It replaced the previously dominant style of black-figure vase painting within a few decades. Its modern name is based on the figural depictions in red color on a black background, in contrast to the preceding black-figure style with black figures on a red background. The most important areas of production, apart from Attica, were in Southern Italy.
Ultrawide formatsUltrawide formats refers to photos, videos, and displays with greater than 2. There were multiple moves in history towards wider formats, including one by Disney, with some of them being more successful than others. Cameras usually capture ultra-wide photos and videos using an anamorphic format lens, which shrinks the extended horizontal field-of-view (FOV) while saving on film or disk. Before computer monitors became a separate product line, televisions were used as displays for computers such as Timex Sinclair 1000.
