Abstract: A high-brightness picosecond laser system, comprising a fully polarization-maintaining fiber picosecond seed laser (1), a fiber collimator (2), a space isolator (3), a polarization splitting prism (5), a first-stage solid traveling wave amplifier (6), a second-stage solid traveling wave amplifier (7), and a third-stage solid traveling wave amplifier (8) which are sequentially arranged in the laser transmission direction. The first-stage solid traveling wave amplifier (6) is located on the transmission light side of the polarization splitting prism (5), the second-stage solid traveling wave amplifier (7) is located on the reflected light side of the polarization splitting prism (5), and the fiber collimator (2) is connected to the fully polarization-maintaining fiber picosecond seed laser (1) by means of a tail fiber.

Abstract: The present disclosure provides a pluggable connecting device for a contactor and a contactor, the contactor including a housing, a coil framework located inside the housing, the coil framework provided with a first and a second connecting sheet, and an electromagnetic coil wound on the coil framework, two ends of the electromagnetic coil electrically connected to the first and second connecting sheets. The pluggable connecting device includes an insulated connecting member, and a first and second conductive elements which are fixedly connected with the insulated connecting member. The first conductive element is provided with an insertion end and a wiring end which are arranged oppositely, the second conductive element is provided with an insertion end and a wiring end which are arranged oppositely, and the insertion ends of the first and second conductive elements are configured for connection with the first and second connecting sheets respectively in a pluggable manner.
