Abstract

The invention discloses a high-precision temperature control device for a large-diameter crystal, relates to a crystal temperature control device and aims at solving the problems that an existing heating device cannot realize precise temperature control of the large-diameter crystal and cannot maintain the temperature gradient of the crystal within 0.2 DEG C. A heater is fixed on the circumferential face of the excircle of a copper ring. The straight end faces of two inner check rings are arranged in an opposite mode, are arranged in the copper ring in a sleeved mode and are in detachable connection with the copper ring in the radial direction. A vertically-arranged crystal is fixed between the straight end faces of the two inner check rings. An inner fixed end cover is fixedly connected with the copper ring. A window glass sheet is fixed on the inclined end faces of the inner check rings in a sealing mode through the inner fixed end cover. The outer side of the heater is sleeved with an outer shell. The two ends of the outer shell are fixed with an outer fixed end cover. A temperature measuring thermal couple is fixed on the copper ring. A display instrument of the temperature measuring thermal couple is arranged on a temperature controller. The temperature measuring thermal couple is connected with the display instrument of the temperature measuring thermal couple through a wire. The display instrument transmits temperature to the temperature controller. The temperature controller is connected with the heater through a wire. The high-precision temperature control device for the large-diameter crystal is used for high-precision temperature control of the large-diameter crystal.

Description

technical field [0001] The invention relates to a crystal temperature control device. Background technique [0002] Frequency doubling conversion technology is an important method to obtain high-energy lasers. It mainly obtains high-frequency, high-energy lasers through the frequency doubling effect of crystals such as KDP, DKDP, and ADP. The frequency doubling conversion efficiency of the crystal can be greatly reduced under a small temperature change, so high-precision temperature control is required for the crystal. In many fields, the demand for large-beam high-frequency lasers is becoming more and more urgent. At the same time, 90° non-critical phase matching technology has a large effective nonlinear optical coefficient, small phase matching angular sensitivity, no optical walk-off and Due to the advantages of high utilization rate and more and more applications, the temperature control accuracy of large-diameter crystals is required to be higher and higher. [0003]...
