| Littrow Prisms |
|
Because Brewster Prisms'angles are chosen, rays at minimum deviation
both enter and exit the prism at the Brewster angle. In this
case, surface reflection losses are negligible. They are often
used inside the cavities of lasers operating on very low gain
laser transitions, where even slight reflection losses may be
intolerable. They are also used to select wavelength from a
multi-wavelength laser. |
