Description

Technical Field

[0001] The utility model relates to the field of lasers, and more particularly to a coaxial red light device. Background Art

[0002] The working principle of a laser is mainly based on the principles of stimulated emission and optical resonance. In a laser, a pump source provides energy to excite the electrons of atoms or ions in the laser medium, causing them to be in an excited state. When the excited atoms or ions transition to the ground state, a beam of light with the same frequency as the light of the pump source and good coherence is emitted, namely the laser beam. Two highly reflective optical mirrors are installed in the optical resonator, one of which is a semi-transmissive mirror and the other is a total reflective mirror. Through multiple reflections in the optical resonator, the intensity of the laser is enhanced, and a laser output optical path is formed to become the laser beam; a coaxial red light device refers to an auxiliary device externally installed on a laser when the laser needs to be assisted by red light for operations such as measurement during operation.

[0003] When existing lasers need red light operation, they can only be installed separately. It is necessary to adjust the position and angle to achieve the best coaxial effect, and various factors such as the installation space also need to be considered, and the operation process is relatively complex.
