Dispersing Prism, Brewster Angle, LaKL21, for Ultrashort Pulses

Manufacturer's part number :


Manufacturer Altechna


Description :

LakL21 Brewster angle dispersing prisms are essential parts in most of ultrashort pulse laser systems. These prisms are used intracavity to compensate for dispersion of fixed cavity optics, such as active gain medium. But in most of cases they are used as extra-cavity elements to manipulate pulse characteristics.
