CRYSTAL SWITCHING DEVICE SUITABLE FOR OPTICAL PARAMETRIC OSCILLATOR

WIPO Patent Application WO/2022/083105

A1

Disclosed in the present invention is a crystal switching device suitable for an optical parametric oscillator, comprising a switching disc, a transmission disc, connection members and a positioning device; the switching disc and the transmission disc are coaxially provided on a fixed shaft; the switching disc is located above the transmission disc; the switching disc is provided with a plurality of sub-discs, and the sub-discs do not overlap; the connection member is provided on the outer edge of each sub-disc; a positioning hole is provided at the free end of each connection member; the transmission disc is rotated to drive the sub-discs of the switching disc to rotate and stops rotating when the sub-discs of the switching disc rotate to the positioning device; the positioning device extends out of a positioning shaft and is combined with the positioning holes in a positioning manner, so that switching of a crystal fixed by the connection member on each sub-disc is completed. According to the present invention, a standby crystal can be automatically switched inside the laser system, and the endurance operation of the oscillator is ensured.
