OVERVIEW

Littrow prisms by STANDA.

Littrow prisms usually are 30 – 60 – 90 deg prisms. The uncoated Littrow prism can disperse white light into its spectrum; the coated Littrow prism diverts the beam at a 60 deg angle without inverting or reversing the image. Littrow prisms can also be used as retro-reflecting Brewster prisms, as shown in the picture. They are positioned so that beam which enters front side of prism suffers Brewster angle and falls normal to the flat surface and is reflected back along the same path.

These prisms are useful in laser cavities where the wavelength of the return beam can be selected by tilting the prism slightly. In this way the gain of the cavity can be tuned to a specific laser line.
