Diffraction grating — A very large reflecting diffraction grating. In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions. The directions of these beams … Wikipedia
Echelle grating — An echelle grating (from French, échelle , meaning stairs or ladder) is a type of diffraction grating which is characterised by a relatively low grooves density but is optimized for high diffraction orders. Echelle gratings are, like other types… … Wikipedia
Fiber Bragg grating — A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the… … Wikipedia

Ultrafast monochromator — In the diffraction of an ultrashort pulse (in the femtosecond, or lower, time scale) with a grating,apart spectral filtering, there occurs a time stretching due to the difference in the path length among the rays diffracted, even of equal… … Wikipedia
Optical vortex — An optical vortex (also known as a screw dislocation or phase singularity) is a zero of an optical field, a point of zero intensity. Research into the properties of vortices has thrived since a comprehensive paper by Nye and Berry, in 1974,[1]… … Wikipedia
Prism compressor — A prism compressor is an optical device used to shorten the duration of a positively chirped ultrashort laser pulse by giving different wavelength components a different time delay. It typically consists of two prisms and a mirror. Figure 1 shows … Wikipedia
Multiphoton intrapulse interference phase scan — (MIIPS) is a method used in ultrashort laser technology that simultaneously measures (phase characterization), and compensates (phase correction) femtosecond laser pulses using an adaptive pulse shaper. Current ultrashort laser pulse… … Wikipedia
Fiber laser — A fiber laser or fibre laser is a laser in which the active gain medium is an optical fiber doped with rare earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, and thulium. They are related to doped fiber amplifiers,… … Wikipedia
