Circular Polarizer / Phase Retarder Laser Optics, Heads, and Beam Delivery Components

KD*P Pockels Cell Components
from CRYSTECH, Inc.

KD*P (Potassium Dideuterium Phosphate) is the most widely used material for electro-optical applications due to its excellent E-O properties. An electro-optic material such as KD*P can alter the polarization state of light passing through it, when an applied voltage induces birefringence change in... [See More]

Polarizer-Analyzer-Attenuator
from II-VI INFRARED

Polarizer-Analyzer-Attenuator is a stacked series of ZnSe plates placed at Brewster ™s angle to an incoming beam. At each plate, virtually all of the p-polarized component is transmitted, while most of the s-polarized component is reflected. The net result, after the beam has traversed several... [See More]

Prisms & Rhombs
from II-VI INFRARED

It ™s often necessary to alter or manipulate the source ™s polarization. For example, a reflective phase retarder converts linear to circular polarization and improves the laser cutting quality. (For reflective phase retarders, please see Phase Retarders.) However, most polarization... [See More]

Reflective Phase Retarders
from II-VI INFRARED

Metal cutting and other critical laser operations are sensitive to any variation in kerf width or cross-section. The kerf ™s quality depends on the polarization orientation relative to the cut direction. This is illustrated in Figure 1. Current theory suggests that the assumption of a focused... [See More]
