    en.wikipedia.org/wiki/Schmidt–Pechan_prism

    A Schmidt–Pechan prism is a type of optical prism used to rotate an image by 180°. These prisms are commonly used in binoculars as an image erecting system. The Schmidt–Pechan prism makes use of a roof prism section (from the German: "Dachkante", lit. roof edge ). Binoculars designs using Schmidt–Pechan prisms can be constructed more ...

  6. Organic laser - Wikipedia

    en.wikipedia.org/wiki/Organic_laser

    An organic laser is a laser which uses an organic (carbon based) material as the gain medium. The first organic laser was the liquid dye laser. [1] [2] These lasers use laser dye solutions as their gain media. Organic lasers are inherently tunable and when configured as optimized multiple-prism grating laser oscillators can yield efficient ...

  7. Tunable laser - Wikipedia

    en.wikipedia.org/wiki/Tunable_laser

    A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner. While all laser gain media allow small shifts in output wavelength, only a few types of lasers allow continuous tuning over a significant wavelength range. There are many types and categories of tunable lasers. They exist in the gas, liquid, and ...
