Description

Technical Field

[0001] The utility model relates to the field of lasers, in particular to a laser beam guiding mechanism and laser equipment. Background Art

[0002] In optical experiments, the output laser beam of the pump source is often guided to a specific laser system to obtain a laser with a certain wavelength and pulse width. Laser pumping is the action of energy transfer from an external source to the laser working material. The energy is absorbed into the medium and produces excited states in the atoms. The pump source can be coupled from the focusing optical system to the working material, with small coupling losses and relatively high utilization of the working material for the pump source. Due to the advantages of high pumping efficiency, good mode matching and wavelength matching, it has become one of the key development directions of laser science. During the installation process of the pump source and the wavelength extension laser system, position errors are prone to occur. The traditional installation method cannot ensure that the laser beam output by the pump source can smoothly enter the wavelength extension laser system, and there is an installation error between the pump source and the wavelength extension laser system. Utility Model Content

[0003] Based on this, it is necessary to provide a laser beam guiding mechanism and laser equipment, which can adjust the laser beam angle through the laser beam guiding mechanism to compensate for the installation error between the pump source and the wavelength expansion laser system, which helps to ensure that the laser beam output by the pump source can smoothly enter the wavelength expansion laser system and improve the working efficiency of the laser equipment.

[0004] A laser beam guiding mechanism for adjusting an optical path between a pump source and a wavelength extension laser system, comprising:

[0005] A first mounting member, used to be fixed to the pump source, wherein the first mounting member is provided with a rotatable first reflecting mirror;

[0006] A second mounting member, used to be fixed to the wavelength extension laser system, wherein the second mounting member is provided with a rotatable second reflector;

[0007] a telescopic member connecting the first mounting member and the second mounting member, wherein the telescopic member can change the distance between the first mounting member and the second mounting member by telescoping;

A connected light guide channel is formed among the first mounting member, the telescopic member and the second mounting member, and the first reflector and the second reflector are used to control the direction of the optical path in the light guide channel. The laser beam emitted by the pump source is reflected to the telescopic member through the first reflector of the first mounting member, and the laser beam passing through the telescopic member is reflected to the wavelength extension laser system through the second reflector of the second mounting member. In the above process, the laser beam can be reflected from the pump source to the wavelength extension laser system through the light guide channel of the laser beam guiding mechanism. Different from the traditional method of using a reflector alone to adjust the laser beam angle to compensate for the position error between the pump source and the wavelength extension laser system, the laser beam guiding mechanism can adjust the laser beam angle through the laser beam guiding mechanism to compensate for the installation error between the pump source and the wavelength extension laser system, which helps to ensure that the laser beam output by the pump source can smoothly enter the wavelength extension laser system and improve the working efficiency of the laser equipment.

[0032] Lasers are widely used in the field of optics. The three major functional components of a laser are a pump source 80, a working substance, and a resonant cavity. The pump source 80 provides a light source for the laser, the working substance is used to amplify the light after absorbing the energy provided by the pump source 80, and the resonant cavity is a loop between the pump light source and the working substance. The resonant cavity oscillates and selects a mode to output laser light. The pump source 80, as an energy source, is used to generate photons to excite the working substance. The photons emitted by the pump source 80 pump the particles in the working substance from the ground state to a high energy level to achieve a particle number inversion. Laser pumping is the action of energy transfer from an external source to the laser working substance. Energy is absorbed in the medium and produces excited states in the atoms. When the number of particles in an excited state exceeds the number of particles in the ground state or a less excited state, population inversion can be achieved. In this case, a stimulated emission mechanism can occur, and the medium can be used as a laser or an optical amplifier. The pump power must be higher than the laser threshold of the laser. In optical experiments, the output laser beam of the pump source 80 is often guided to a specific wavelength extension laser system 90, so as to obtain a laser with a certain wavelength and pulse width. During the installation process of the pump source 80 and the wavelength extension laser system 90, there will be a position error between the pump source 80 and the wavelength extension laser system 90, and it cannot be guaranteed that the laser beam output by the pump source 80 can smoothly enter the wavelength extension laser system 90, thereby reducing the working efficiency of the laser device. To this end, an embodiment of the present application provides a laser beam guiding mechanism 10, which can ensure that the laser beam output by the pump source 80 can smoothly enter the wavelength extension laser system 90, thereby improving the working efficiency of the laser device.

[0033] See also Figure 1 and Figure 2 The present application provides a laser beam guiding mechanism 10, which is used to adjust the optical path between a pump source 80 and a wavelength extension laser system 90. The laser beam guiding mechanism 10 includes a first mounting member 20, a second mounting member 30 and a telescopic member 40. The first mounting member 20 is used to be fixed to the pump source 80. A rotatable first reflector 21 is provided in the first mounting member 20. The laser beam emitted by the pump source 80 can be emitted to the first reflector 21. The second mounting member 30 is used to be fixed to the wavelength extension laser system 90.

In some embodiments, the telescopic member 40 connects the first mounting member 20 and the second mounting member 30, and the first mounting member 20 and the second mounting member 30 are respectively provided at both ends of the telescopic member 40. In some embodiments, the telescopic member 40 can be extended or shortened along its axial direction. Since the telescopic member 40 is connected to the first mounting member 20 and the second mounting member 30, the distance between the first mounting member 20 and the second mounting member 30 can be adjusted by adjusting the telescopic member 40. In some embodiments, a connected light guide channel 50 is formed in the first mounting member 20, the telescopic member 40, and the second mounting member 30, and the first reflector 21 and the second reflector 31 are used to control the direction of the light path in the light guide channel 50. Specifically, the laser beam emitted by the pump source 80 can be reflected to the light guide channel 50 in the telescopic member 40 through the first reflector 21 of the first mounting member 20, and the laser beam passing through the telescopic member 40 is reflected to the wavelength extension laser system 90 through the second reflector 31 of the second mounting member 30. In the above process, the laser beam can be reflected from the pump source 80 to the wavelength extension laser system 90 through the light guide channel 50 of the laser beam guiding mechanism 10. Since the telescopic member 40 can adjust the distance between the first mounting member 20 and the second mounting member 30, the length of the telescopic member 40 in the laser beam guiding mechanism 10 can be adjusted according to the distance between the pump source 80 and the wavelength expansion laser system 90 to ensure that the laser beam output by the pump source 80 smoothly enters the wavelength expansion laser system 90.
