Abstract

The invention relates to a temperature control system and a method for frequency doubling crystal. The temperature control system comprises a frequency doubling crystal unit and a temperature controlcircuit device, the frequency doubling crystal unit comprises a crystal base and a frequency doubling crystal, the frequency doubling crystal is fixed over the crystal base, a groove is formed under the crystal base, a resistance wire is fixed in the groove under the crystal base, and a temperature sensor is close to the frequency doubling crystal; the temperature control circuit device comprisesan MCU and a current driving module. The power supply module is electrically connected with the MCU and the current driving module; wherein the MCU is in communication connection with a remote controlend, the MCU is connected with the current driving module and the analog-to-digital converter, controls the current driving module and acquires a temperature value converted by the analog-to-digitalconverter, the current driving module is connected with the resistance wire and controls the current of the resistance wire, and the analog-to-digital converter is connected with the temperature sensor and acquires a temperature value of the temperature sensor. The temperature of the frequency doubling crystal is controlled in a resistance wire heating mode, and accurate adjustment of the temperature of the frequency doubling crystal is achieved by controlling the heating power of the resistance wire.

Description

technical field [0001] The invention relates to a temperature control system and method for frequency doubling crystals. Background technique [0002] The frequency doubling crystal is a nonlinear material that is very sensitive to temperature. The heat on the frequency doubling crystal will change when the laser is turned on and off, which will directly affect the output laser pulse energy and beam quality. Therefore, keeping the temperature of the frequency doubling crystal stable during the working process is an important link in the entire laser. [0003] At present, most of the working temperature control of the frequency doubling crystal is realized by controlling the TEC. During the working process, the temperature control device can heat or cool the crystal by controlling the flow of the current in the TEC. The realization process is complicated and difficult to control. At the same time, the installation requirements of the TEC High, the cost of the temperature con...
