Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1-3, an ultrashort laser resonant system disclosed by the utility model comprises an optical path bottom plate 1, wherein a light-gathering cavity body 2 is arranged on the optical path bottom plate 1, a lamp tube 21 and a crystal rod 22 are arranged in the light-gathering cavity body 2, the lamp tube 21 is preferably but not limited to a xenon lamp, the chemical property is stable, and the use safety is high. Meanwhile, the xenon lamp and the crystal rod 22 are both horizontally arranged in the light-gathering cavity body 2, so that most of light emitted by the xenon lamp can be irradiated on the crystal rod 22 to form laser, and the crystal rod 22 absorbs the light emitted by the xenon lamp and then emits the light to two ends along the length direction of the crystal rod. A cooling device is preferably arranged in the condensation cavity body 2, so that heat emitted by the hernia lamp during operation can be effectively taken away.
One side of the light condensation cavity body 2 is provided with a total reflection lens 3, the total reflection lens 3 is specifically adapted to the position setting of the crystal rod 22, and the total reflection lens 3 is perpendicular to the crystal rod 22, namely, the total reflection lens 3 and the crystal rod 22 are arranged at an included angle of 90 degrees. The other side of spotlight chamber body 2 is equipped with speculum 4, speculum 4 with crystal stick 22 is 45 contained angles setting, one side of speculum 4 is equipped with half mirror plate 5 rather than looks adaptation, half mirror plate 5 with crystal stick 22 looks parallel, namely speculum 4 locates crystal stick 22 with between half mirror plate 5. Further, both ends of the crystal rod 22 respectively extend out of the light-gathering cavity body 2, so that the light absorbed by the crystal rod 22 can be smoothly emitted and pass through the total reflection lens 3 and the reflection mirror 4.
Specifically, as shown in fig. 3, the light source generated by the laser is completed by the cooperation of the crystal rod 22 and the xenon lamp, the laser emitted from two ends of the crystal rod 22 is emitted to the total reflection lens 3 from one end, and the total reflection lens 3 also reflects the laser back to the crystal rod 22; on the other hand, the laser emitted from the other end of the crystal rod 22 is emitted to the reflecting mirror 4, and because the reflecting mirror 4 is arranged at 45 degrees, the path of the laser is turned to 90 degrees and is conveyed to the semi-reflecting mirror 5, meanwhile, the semi-reflecting mirror 5 also reflects the laser back to the crystal rod 22 in the original path, when the laser repeatedly passes through the total reflecting mirror 3 and the semi-reflecting mirror 5 and back and forth oscillation reflection reaches a certain energy threshold, the laser finally outputs welding laser through the semi-reflecting mirror 5, the path of the laser is greatly shortened, the production requirement of small-sized equipment can be met, and meanwhile, the internal space of the large-sized equipment can be saved when the laser is installed in the large-sized equipment.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, or alternatives falling within the spirit and principles of the utility model.
