cathode sputtering
The method of disintegrating the substance of the cathode by bombarding it with ions and depositing it on another electrode or electron tube envelope.
chirped-pulse amplification laser
A laser whose pulses are expanded, using gratings and optical fibers, before amplification and compressed to increase beam intensity without damage to the optical train.
chirped-pulse amplification
Chirped pulse amplification (CPA) is a technique used in laser physics to amplify ultrashort laser pulses to high energies without causing damage to the amplifying medium. The method was first...
concave grating
A reflecting grating ruled on a concave spherical surface that not only disperses the light but focuses the spectrum. The great advantage of this grating lies in the fact that no separate collimating...
concave holographic grating
The generation of a grating on a concave spherical blank by the holographic process. In this way, ghost images and intense stray light are avoided.
covered groove
A technique used in integrated optics where a groove is cut on a substrate surface and covered by a thin film to facilitate the construction of filters, resonators, beamsplitters and grating couplers...
crystal grating
A crystal that may serve as a diffraction grating if mounted effectively.
Czerny-Turner design
A form of monochromator optical system consisting of two spherical concave mirrors used in conjunction with a movable diffraction grating.
