Abstract
The invention relates to a polarization output annular resonant cavity with a tunable output rate and an adjustable output mirror. The resonant cavity comprises a gain medium, a polarized light adjusting device and at least three reflection cavity mirrors, and at least one of the reflection cavity mirrors is a polarization reflecting mirror; pump light enters a gain medium after passing through an input mirror, and oscillation light generated by the gain medium circulates in the annular resonant cavity; a first polarization reflecting mirror encountered by the oscillating light after leaving the polarized light adjusting device is used as the output mirror of the annular resonant cavity, and the polarization reflecting mirror highly reflects the oscillating light entering the polarized light adjusting device and highly transmits the polarized light of the other component; and the polarized light adjusting device can adjust the component of the horizontal polarized light in the oscillation light so as to tune the output rate of the annular resonant cavity. The output rate of the annular resonant cavity is tunable, the requirement of the annular resonant cavity for light emitting efficiency optimization can be greatly met, meanwhile, the number and the positions of the output mirrors can be changed, the light emitting direction can be changed, and more choices can be provided for the design of the laser.
Description
technical field [0001] The invention relates to the technical field of solid lasers, in particular to a polarization output ring resonator with adjustable output rate and adjustable output mirror. Background technique [0002] Improving the light extraction efficiency of the laser resonator is a pursuit goal of designing lasers. High light extraction efficiency can not only reduce the power consumption of the laser, but also reduce the thermal load of the laser system, which is of great help to the engineering of the laser. An important factor affecting the light output efficiency of the laser resonator is the output rate of the resonator. Different gain media, different cavity lengths, and different cavity structures have different output rates when they have the best light output effect. Therefore, the resonant cavity with tunable output rate can achieve the best light output efficiency of the laser. [0003] In traditional lasers, the output rate of the resonator is rea...
