Abstract
The utility model discloses a semiconductor laser focusing device, which comprises a laser collimation lens and a laser focusing lens, wherein both the laser collimation lens and the laser focusing lens are cylindrical lenses and are perpendicular to each other; and the diameter of the laser collimation lens is less than that of the laser focusing lens. The semiconductor laser focusing device disclosed by the utility model is simple in structure, convenient in assembly, high in coupling efficiency, good in focusing stability, lower in cost, and the like.
Description
Technical field
The utility model relates to a kind of semiconductor laser focalizer, especially a kind of device that the laser of semiconductor laser array illuminating source output is collimated and focuses on.
Background technology
Because semiconductor laser array device output laser angle of divergence on orthogonal direction differs greatly; Its luminous size is also different, and present focalizer generally is made up of three parts, at first to output laser alignment; Then it is carried out shaping, use lens focus at last.These install all more complicated, and existence is processed, shortcomings such as resetting difficulty is big, manufacturing cost height.
The utility model content
The purpose of the utility model be provide in order to address the above problem a kind of simple in structure, coupling efficiency is high, focusing stability good and debug laser focusing device easily.
The utility model is realized through following technical scheme:
The semiconductor laser focalizer of the utility model; Comprise laser alignment lens and laser focusing lens; Said laser alignment lens and said laser focusing lens are cylindrical lens; Said laser alignment lens are vertical each other with said laser focusing lens, and the diameter of said laser alignment lens is less than the diameter of said laser focusing lens.
As preferably, said laser alignment lens are optical fiber cylinder laser alignment lens.
As preferably, said laser alignment lens and said laser focusing lens are processed by pure quartz material.
The beneficial effect of the utility model is:
(1) simple in structure, easy to assembly; (2) coupling efficiency is high, focusing stability is good; (3) cost is lower.
Description of drawings
Fig. 1 is the front view of semiconductor laser focalizer;
Fig. 2 is the vertical view of semiconductor laser focalizer.
The accompanying drawing sign:
1, laser alignment lens, 2, laser focusing lens, 3, the semiconductor laser array device
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify:
As depicted in figs. 1 and 2; The utility model semiconductor laser focalizer; Comprise laser alignment lens 1 and laser focusing lens 2; Laser alignment lens 1 are cylindrical lens with laser focusing lens 2, and laser alignment lens 1 are vertical each other with laser focusing lens 2, and the diameter of laser alignment lens 1 is less than the diameter of laser focusing lens 2.The illuminating source of semiconductor laser array device 3 sends laser, and the laser that the illuminating source of 1 pair of semiconductor laser array device 3 of laser alignment lens sends collimates, and the laser after laser focusing lens 2 collimation focuses on then.
Laser alignment lens 1 are optical fiber cylinder laser alignment lens.Laser alignment lens 1 are processed by pure quartz material with laser focusing lens 2.
The above preferred embodiment that is merely the utility model that discloses can not limit the interest field of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
