Abstract
The invention discloses a frequency doubling crystal heating device and a method thereof. A frequency doubling crystal is fixed on a heat insulation rack; a temperature sensor is arranged between the heat insulation rack and the frequency doubling crystal; the heating device is provided with a pulsed light generator and a controller; the controller real-timely monitors the temperature of the frequency doubling crystal detected by the temperature sensor and controls the pulsed light generator to produce heating pulsed light; and the heating pulsed light emitted by the pulsed light generator penetrates the frequency doubling crystal. When the temperature of the frequency doubling crystal is higher than the set value, the pulsed light generator stops producing pulsed light; and when the temperature of the frequency doubling crystal is lower than the set value, the pulsed light generator produces pulsed light to heat the frequency doubling crystal, so that operating laser can pass through the frequency doubling crystal in the set temperature. The heating device and method adopt non-contact heating, thereby achieving cleanness, zero contamination and uniform and stable internal and external heating; and the light pulse heating time and temperature are controllable, the light transmission route can not be influenced and the efficiency of the frequency doubling crystal is effectively improved.
