The T850 Pockels Cell Driver is a fraction of the size, power consumption, and price of conventional devices. Its small size and very low power requirements allow it to be mounted immediately adjacent to the Pockels Cell in an optical system. There are no fans or other sources of vibration.

Highland can furnish complementary standard and custom timing controllers to manage pulse picking, Q-switching, chirped pulse amplification, cavity dumping, and two-photon microscopy.

The T850 is available as an OEM product under NDA only. The minimum order quantity starts at 50 pieces. Loaner units are available for demonstration for up to 30 days.

The T850 is available as an OEM/custom product. Specifications are given to illustrate functionality.
