Embodiment Construction

[0024] The present invention is described in further detail below by specific embodiment:

[0025] see figure 1 , which is a flow chart of the first embodiment of the getter laser irradiation activation method of the present invention. The method for activating the built-in getter of the laser gyroscope of the present invention irradiates the laser beam on the surface of the getter located in the gas storage hole of the laser gyroscope through a fiber coupler, continuously irradiates and heats the getter and activates the getter. In the present embodiment, its steps are as follows:

[0026] Step 1. Adjust the position of the fiber coupler that outputs the laser beam. You can use a tool to fix it at the center of the large hole of the laser gyroscope, so that the light output direction is relatively perpendicular to the surface of the getter;

[0027] Step 2. Turn on the laser and adjust the output power of the laser;

[0028] Step 3. The laser is output from the fiber coupl...

Abstract

The present invention relates to a getter activation method, and particularly relates to a laser gyro built-in getter laser irradiation activation method. The getter activation method uses a laser irradiation heating technology, a laser is a high-power semiconductor laser, laser wavelength is within a near infrared band, laser beams are guided and outputted by an optical fiber coupler for irradiation on the surface of a laser gyro built-in getter, laser power is adjusted, and by continuous irradiation for a period of time, the effect of activation can be achieved. The laser gyro built-in getter activation method is high in activating efficiency and easy to operate, and has actual application value.

Description

technical field [0001] The invention belongs to vacuum technology, in particular to a method for activating a built-in getter in a laser gyroscope. Background technique [0002] As a vacuum system that requires long life and high stability, the laser gyro needs a built-in getter to absorb the impurity gas inside the cavity to ensure the purity and proportion of the working gas medium, thereby increasing the working life and long-term stability. [0003] The built-in getter must first be activated by heating to remove the miscellaneous gas in its own body before it can play the role of inhalation. [0004] At present, there are three commonly used getter activation methods in vacuum systems, namely, direct electric heating method, thermal radiation heating method and high-frequency induction heating method. The first is that there is a heat submerged inside the getter, and the getter is directly heated and activated after the heat is energized. The second is to be heated by ...
