Problems solved by technology

Its main disadvantage is that the transmittance of the existing output mirrors is fixed and cannot be changed randomly
If you want to change the output rate of the laser, you must replace the output mirror, which is very troublesome to operate and requires professional laser technicians

Embodiment 1

[0021] refer to figure 1 As shown, a kind of resonant cavity structure based on the magneto-optical effect provided by the present embodiment includes: two laser high reflection mirrors 1 arranged at intervals and a polarization device and a magnetic field generator ( not shown) and magneto-optical material body 2. Specifically, the resonant cavity is a linear resonant cavity, and the two laser high-reflection mirrors 1 are arranged opposite to each other. The incident beam is reflected by the two laser high-reflection mirrors 1 to oscillate and amplify in the resonant cavity to form an oscillating beam (ie, e-light). The polarizer is a Glan-Taylor prism 4 , and the oscillating light beam (ie, e-light) can propagate through the Glan-Taylor prism 4 and the magneto-optical material body 2 .

Abstract

The invention relates to a resonant cavity structure based on a magneto-optical effect and a laser with the resonant cavity. The resonant cavity structure based on the magneto-optical effect comprisestwo laser high-reflectivity mirrors which are arranged at an interval, and a polarization device, a magnetic field generator and a magneto-optical material body which are arranged between the two laser high-reflectivity mirrors, wherein the magnetic field generator corresponds to the magneto-optical material body; a magnetic field generated by the magnetic field generator has a certain componentin the propagation direction of the oscillating beam at the current position; the magneto-optical material body changes the polarization direction of the oscillation light beam under the action of a magnetic field, and the oscillation light beam with the polarization direction changed by the magneto-optical material body is separated by the polarization device into an oscillation light beam whichcontinues to be oscillated and amplified in the resonant cavity and an output light beam which is separated from the resonant cavity to be output. The intensity of the output light beam is related tothe magnetic field intensity, the transmittance of the output light beam can be changed by changing the magnetic field intensity, and parts do not need to be replaced.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a resonant cavity structure based on the magneto-optic effect and a laser with the resonant cavity. Background technique [0002] A laser is generally composed of three parts: a pump source, a laser working medium and a resonant cavity. The resonant cavity is composed of an input mirror and an output mirror. The input mirror is coated with a laser high-reflection film, which is a laser high-reflection mirror; while the laser output mirror is coated with a partial reflection film (that is, has a partial transmittance). The partial reflection of the output mirror is to continuously oscillate and amplify the laser in the resonant cavity, while the transmission is to realize the laser output. Most of the existing laser output mirrors are partially reflected by coating. Its main disadvantage is that the transmittance of the existing output mirrors is fixed and cannot be changed randomly. If y...
