In order to cover the high thermal load and high energy working environment, we designed an integrated shutter device. The device includes a thermal absorber shutter, a piezoelectric ceramic fast shutter, a vacuum chamber and an adjustable height base. Firstly SPECTRA and ANSYS were used to verify the device’s institutional temperature reliability at a thermal power density of 64W/mm2. In addition, the device is suitable for both monochromatic and pink light operation with a horizontal pitch of 15mm. The device is also compatible with both vacuum and atmospheric working environments, and the recollimation of the device is not necessary when switching modes. Finally, the thermal absorber shutter is also able to function as a beam profile monitor, and the position of the spot can be monitored through a viewing window on the cavity.
