Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The present invention uses the tuning disk in the microwave resonator to change the resonant frequency of the resonator, and then changes the loss of the resonator, that is, the Q value, and then uses the change of the Q value at a specific moment to make the upper energy level accumulate enough particle numbers, and finally produces Microwave pulses with a single frequency, this method can effectively improve the problem of low output power and improve output efficiency.

[0028] Such as figure 1 As shown, the Q-switching device of the maser working under the geomagnetic field at room temperature provided by the e...

Abstract

The invention belongs to the technical field of a maser and discloses a Q-switching device and method for a maser working in the room temperature earth magnetic field. According to the method, a control panel, a voice coil motor and a laser are started, the motor is driven through a control panel driving circuit, the frequency and range of the voice coil motor moving back and forth are set, a limit switch is set to prevent a resonant frequency tuning disk from bumping a resonant chamber during movement, a grating scale sensor QH-200 outputs a signal with specific waveform to the control panel,the initial position is set, a signal is outputted by the control panel to the laser, a power peak of the output microwave from a coupling ring is observed by an oscilloscope, after debugging is completed, setting of the initial position is changed, the situation of the i-th work is observed, the power peak of the output microwave is recorded, the Q-switching position is determined through continuously narrowing the range, the final position is finally calibrated, and Q-switching of the maser is completed. The method is advantaged in that problems of relatively low output power and efficiencyexisting in the maser working in the room temperature earth magnetic field can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of masers, and in particular relates to a Q-switching device and method of a maser working under a geomagnetic field at room temperature. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: A maser is a kind of amplification device made by using the principle of stimulated radiation of a radiation field. It is based on a gain material, with the help of laser or other pump energy, through the stimulated radiation of the upper energy level and then A technique for producing monochromatic coherent microwave radiation with extremely low noise. This technology is widely used in atomic clocks and astronomical research. The core device of the maser is the gain medium material, the microwave resonator and the pump energy. During operation, the pump energy pumps the particles of the gain medium to the upper energy level, and the frequency of the electrom...
