Description

Technical Field

[0001] The utility model relates to the technical field of laser light source devices, and particularly relates to a dual-frequency laser light source device. Background Art

[0002] A laser light source device is a device that uses laser technology to generate and emit light beams. The applications of laser light source devices are very extensive. They not only play an important role in fields such as industrial processing and medical treatment, but also play an increasingly important role in scientific research, advanced technologies, and the development of national defense technology.

[0003] In the prior art, a laser light source device cannot provide two frequencies of laser simultaneously within the required time. Therefore, we propose a dual-frequency laser light source device to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that in the prior art, a laser light source device cannot provide two frequencies of laser simultaneously within the required time, and a dual-frequency laser light source device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A dual-frequency laser light source device includes:

[0007] A laser for emitting a laser beam;

[0008] A semi-transparent mirror for distributing the laser beam emitted by the laser;

[0009] A mirror assembly for reflecting the beam distributed by the semi-transparent mirror;

[0010] A driving motor for providing power;

[0011] A lead screw, one end of which is fixedly connected to the output shaft of the driving motor, and the driving motor drives the lead screw to rotate;

[0012] A support seat, which is threadedly connected to the lead screw, and the rotation of the lead screw drives the support seat to move.

[0013] Preferably, the semi-transparent mirror is used to distribute the laser beam emitted by the laser into a first beam and a second beam.

[0014] Preferably, the mirror assembly includes a first mirror, a second mirror, a third mirror, a fourth mirror, and a fifth mirror.

[0015] Preferably, the first mirror, the second mirror, the third mirror, the fourth mirror, and the fifth mirror are used to reflect the second beam into a third beam.

[0016] Preferably, the second reflector and the third reflector are arranged on the support base.

[0017] Preferably, a slider is connected to the support base, and the slider is connected to a slide rail.

[0018] In the present utility model, the beneficial effects of the dual-frequency laser light source device;

[0019] The laser beam emitted by the laser is divided into two beams, namely the first beam and the second beam, by the semi-lens. The second beam forms a third beam after being reflected by the first reflector, the second reflector, the third reflector, the fourth reflector, and the fifth reflector. When dual-frequency laser is required, the driving motor is started, and the driving motor drives the lead screw to rotate, causing the support base connected to the lead screw to move parallelly, thereby driving the reflectors on the support base, namely the second reflector and the third reflector, to move parallelly. At the same time, the optical path between the first reflector and the second reflector, and between the fourth reflector and the third reflector is changed, so that the frequency of the third beam is changed during the movement;

[0020] The present utility model can provide two frequencies of laser simultaneously within the required time to meet the usage requirements. Description of the Drawings

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Refer to Figure 1 , a dual-frequency laser light source device, including:

[0025] A laser 1 for emitting a laser beam 2;

[0026] A semi-lens 3 for distributing the laser beam 2 emitted by the laser 1;

[0027] A reflector assembly for reflecting the beam distributed by the semi-lens 3;

[0028] A driving motor 7 for providing power;

[0029] The lead screw 8 has one end fixedly connected to the output shaft of the driving motor 7, and the driving motor 7 drives the lead screw 8 to rotate;

[0030] The support seat 10 is threadedly connected to the lead screw 8, and the rotation of the lead screw 8 drives the support seat 10 to move.

[0031] In this embodiment, the half mirror 3 is used to split the laser beam 2 emitted by the laser 1 into a first light beam 4 and a second light beam 5.

[0032] In this embodiment, the mirror assembly includes a first mirror 6-1, a second mirror 6-2, a third mirror 6-3, a fourth mirror 6-4, and a fifth mirror 6-5.

[0033] In this embodiment, the first mirror 6-1, the second mirror 6-2, the third mirror 6-3, the fourth mirror 6-4, and the fifth mirror 6-5 are used to reflect the second light beam 5 into a third light beam 9.

[0034] In this embodiment, the second mirror 6-2 and the third mirror 6-3 are arranged on the support seat 10.

[0035] In this embodiment, a slider is connected to the support seat 10, and the slider is connected to a slide rail.

[0036] In this embodiment, the laser beam 2 emitted by the laser 1 is split by the half mirror 3 into two light beams, namely the first light beam 4 and the second light beam 5. The second light beam 5 is reflected by the first mirror 6-1, the second mirror 6-2, the third mirror 6-3, the fourth mirror 6-4, and the fifth mirror 6-5 in sequence to form a third light beam 9. When dual-frequency laser is required, the driving motor 7 is started. The driving motor 7 drives the lead screw 8 to rotate, causing the support seat 10 connected to the lead screw 8 to move parallelly, thereby driving the second mirror 6-2 and the third mirror 6-3 on the support seat 10 to move parallelly. At the same time, the optical path between the first mirror 6-1 and the second mirror 6-2, and between the fourth mirror 6-4 and the third mirror 6-3 is changed. Thus, the frequency of the third light beam 9 is changed during the movement. By changing the rotational speed of the driving motor, the magnitude of the moving frequency of the third light beam 9 relative to the first light beam 4 can be adjusted.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
