  • WIDE ANGLE POCKELS CELLS AND USE THEREOF
    Publication number: 20230384626
    Abstract: A system for switching and collating light contains a focusing lens that focuses a laser. A first linear polarizer receives the focused beam and transmits the focused beam incoming light, polarized at plus 45 degrees, to a Pockels cell. The Pockels cell contains: a first Pockels cell crystal that follows the first linear polarizer; a first internal birefringent crystal plate that compensates for birefringence of the first Pockels cell crystal; a second internal birefringent compensation crystal plate that follows the first plate; and a second Pockels cell crystal, that follows the second plate. The second plate considerably compensates for birefringence of the second Pockels cell crystal. A second linear polarizer receives light from the Pockels cell and transmits light best if the light is polarized at minus 45 degrees to an optical fiber.
