Background technique
The effect of pumping component in laser is mainly by the fiber coupling inside laser at light beam and resonator mode
It matches.Therefore, pumping component plays key effect for beam quality, and the performance for pumping component directly determines working substance
The efficiency of confrontation Pumping light absorption.
Recent years with superpower laser extensive use, to pumping component requirement it is higher and higher.But at present
The pumping component of existing solid state laser has many disadvantages, and such as structure is complicated, adjusts complexity, does not have to the pumping source LD of laser
Protective effect, spotlight effect is poor, and pump light cannot be well along linear transmission, and optical path loss is very big, and efficiency is very low.
Utility model content
Technical problem: in order to solve the defects of prior art, the utility model provides a kind of relatively reliable stabilization of performance
Laser pumping light source coupling device.
Technical solution: a kind of coupling device of laser pumping light source provided by the utility model, including pumping lens barrel, the
One non-spherical lens, the second non-spherical lens；The pumping lens barrel is the tubular structure of both ends open, and place open at one end is equipped with flat
Face protective glass；First non-spherical lens is fixed in pumping lens barrel by lens holder, and second non-spherical lens is logical
It crosses the first washer for being set to the second non-spherical lens two sides and second packing ring is fixed in pumping lens barrel；The lens holder and
It is equipped with spacer ring between first washer, pressing ring is equipped between the second packing ring and plane protective glass.
As an improvement, the spherical surface of first non-spherical lens, the second non-spherical lens is oppositely arranged.
It is improved as another kind, the surface difference of first non-spherical lens, the second non-spherical lens, plane protective glass
It is coated with anti-reflection film.
The utility model has the advantages that the coupling mechanism structure of laser pumping light source provided by the utility model is simple, easy to operate, peace
Dress is convenient, can not only protect to laser pump source LD, and can guarantee that optical path along linear transmission, reduces optical path
Loss improves the beam quality after focusing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the coupling device of laser pumping light source.
Specific embodiment
The coupling device of the utility model laser pumping light source is further illustrated below.

3；The tubular structure that lens barrel 1 is both ends open is pumped, place open at one end is equipped with plane protective glass 9；First non-spherical lens 2 passes through
Lens holder 4 is fixed in pumping lens barrel 1, and the second non-spherical lens 3 is by being set to the first of 3 two sides of the second non-spherical lens
Washer 5 and second packing ring 6 are fixed in pumping lens barrel 1；Spacer ring 7, second packing ring are equipped between lens holder 4 and the first washer 5
Pressing ring 8 is equipped between 6 and plane protective glass 9.
First non-spherical lens 2, the second non-spherical lens 3 spherical surface be oppositely arranged.
First non-spherical lens 2, the second non-spherical lens 3, plane protective glass 9 surface be coated with anti-reflection film respectively；It is anti-reflection
Anti-reflection film commonly used in the art can be selected in film, as long as playing antireflective effect may be implemented the purpose of this utility model.
The effect of each component of the device is:
(1) LD light emitting source is mainly coupled an entirety with other devices by pumping lens barrel；The LD light emitting source of laser is logical
It crosses and fibre-optical splice (SMA90 connector) precession of LD light emitting source is pumped into lens barrel and is locked, such LD light emitting source and pumping lens barrel shape
Integrally；
(2) lens holder be will using optics specialized lens glue by the first non-spherical lens be fixed on lens holder make its at
It is integrated, and will be fixedly mounted in pumping lens barrel；
The effect of (3) first non-spherical lenses is that LD light emitting source is carried out collimating effect, so that optical path is along straightline propagation, the
The surface of one non-spherical lens is coated with anti-reflection film；
(4) spacer ring is to separate the first non-spherical lens and the second non-spherical lens, and have required distance；
(5) second non-spherical lenses are that collimated light is converged to some state, and the second non-spherical lens passes through the first washer
Protection location and installation is carried out with second packing ring；
(6) pressing ring effect is to compress entire internal component, prevents from loosening；
(7) plane protective glass is also to have plated film, is to be bonded with the special glue of optics, prevents resonant cavity reflected
Light damages laser diode pump pumping source LD light emitting source by pumping component.
