Embodiment 1

[0024] Such as figure 2 As shown, a high-power liquid-cooled optical isolator includes a first filter 3 and an optical isolator core 4 in sequence along the incident optical axis of the forward light, and the first filter 3 and the optical isolator core 4 are all arranged on In the water-cooled packaging device 1, the light input into the first filter 3 and the light beam output by the optical isolator core 4 are both approximately parallel light beams with a divergence angle less than 5 degrees.

[0025] The first filter 3 includes an aperture a and lens b3.1 and lens c3.3 located on both sides of the aperture, and the first through hole 3.2 on the aperture a is located at the common focal plane of lens b3.1 and lens c3.3 superior. Diaphragm a can filter out light rays whose angle with the incident optical axis of the forward light is too large.

[0026] The optical isolator core 4 includes a first birefringent crystal 4.1, a Faraday rotator 4.2 and a second birefringent c...

Abstract

The invention relates to an opto-isolator, in particular to a high-power liquid cooling opto-isolator. The high-power liquid cooling opto-isolator comprises a first optical collimator, a first filter, an opto-isolator core and a second optical collimator which are sequentially arranged along a forward light incident light axis, and the first optical collimator, the first filter, the opto-isolator core and the second optical collimator are all arranged in a water cooling packaging device. The first optical collimator is connected with an input optical fiber, and the second optical collimator is connected with an output optical fiber. Due to the fact that the water cooling packaging device is adopted, the heat radiation effect is improved, and the opto-isolator can stably work at high power for a long time.

Description

technical field [0001] The invention relates to an optical isolator, in particular to a high-power liquid-cooled optical isolator. Background technique [0002] Optical isolators are devices that only allow light to pass in one direction while blocking light in the opposite direction. Devices such as semiconductor lasers and fiber lasers are sensitive to light reflected from connectors, fusion points, etc., and reflected light may cause damage to the device. Therefore, an optical isolator is needed to block the reflected light. At present, most of the optical isolators used are used for low-power beams. When it comes to high-power beams, problems such as poor heat dissipation and low isolation are prone to occur. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a high-power liquid-cooled optical isolator, which has the advantages of high isolation and good heat dissipation effect, and can be used for high...
