Abstract

The Raman laser modulation device and method provided in the embodiments of the present application first emits laser light to the laser transmission channel, and then adjusts the positional relationship between the laser transmission channel and the optical microcavity, so that the laser passes through the laser transmission channel and the The optical microcavity resonant coupling described above. Then, the laser is further adjusted to make a mechanical frequency comb phenomenon appear in the image displayed by the radio frequency spectrometer to generate Raman laser. The Raman laser modulation method and device described in the present application effectively switch the Raman laser by introducing the mechanical frequency comb characteristic, and realize the function of an optical switch. This application simplifies the preparation process and provides a new idea for the application of Raman laser generation and optical switch.

Description

technical field [0001] The present application relates to the field of precision instruments, in particular to a Raman laser modulation device and method. Background technique [0002] Whispering gallery mode optical microcavities have extremely high quality factor and small mode volume, which can greatly enhance the interaction between light field and matter, and have attracted more and more research interest in the field of Raman laser generation. In traditional technology, the technology of using optical microcavity to generate Raman laser can be divided into two categories according to the different gain mechanisms. One is to use materials like semiconductors and doped rare earth elements to achieve gain amplification. The other is the use of nonlinear effects to achieve laser gain amplification. [0003] In the traditional technology, the preparation process required by the optical microcavity to generate Raman laser is very complicated, and it cannot effectively real...
