Paper Abstract
Plasma Pockels cell (PPC), which can use a thin crystal to perform the uniform electro-optical effect, is ideal component
as average-power optical switch with large aperture. In this paper, by reformative design and employing a capacity to
share the gas discharge voltage, the DKDP PPC driven by one pulse is realized. As gas breakdown delay time is stable,
and discharge plasma is uniformly filled the full aperture, it meets the demand of plasma electrode for the repetition-rate
PPC with DKDP crystal. A rep-rate plasma Pockels cell (PPC) with Φ30mm aperture has been fabricated. It is optimized
with the limited space of repetition rate diode pumped laser. The specification of the PPC is: static transition of 97.2%,
switching efficiency of 99.8%, the switch rising time of 8.6ns. In the LD pumped Yb:YAG plate laser system, the PPC
can steadily work on 10Hz repetition rate performed as Q-switch. The key problems in PPC are analyzed for
repetition-rate application, and thermo-optical effects are simulated by means of numerical modeling when average
power laser is loaded on the electro-optical crystal. Furthermore, the principium design of rep-rate PPC with
longitudinally conductive cooled structure is described in this paper. It will efficiently abate the thermo-optical effects
under repetition rate application.
