Abstract
The invention provides an indicating light generation device for an optical fiber laser. The indicating light generation device comprises an encapsulation package, and an optical fiber end cap, a beam shaping telescope, a free space isolator, a frequency doubling crystal and a diaphragm which are arranged in sequence in the encapsulation package along a light path, wherein the frequency doubling crystal is arranged on a fixture; the fixture is controlled through an electromagnetic valve. The frequency doubling crystal is inserted into the light path when indicating light positioning needs to be provided by the laser, and is extracted from the light path when indicating light positioning is not needed, so that the loss of laser power and interference light are reduced.
Description
[technical field]
The present invention relates to a kind of pilot light generating means of fiber laser.
[background technology]
Laser freuqency doubling technology refers to: utilize the quadratic nonlinearity effect of nonlinear crystal under light laser effect, make frequency be the laser of ω by becoming the frequency doubled light that frequency is 2 ω after crystal, be called frequency doubling technology, or secondary harmonic generation (SHG).As the laser of 1064nm is passed through frequency-doubling crystal, become the green glow of 532nm.Frequency doubling technology expands the wave band of laser, can obtain the laser of more short wavelength.
Existing general location technology is by adding visible light source and high saturating, the high anti-eyeglass of visible wavelength of 1064nm in fiber laser light path, this situation completes being coupled of visible ray and infrared light in fiber laser light path, major defect is to introduce stray light and loss, cause laser performance shakiness and power attenuation, in addition be less than 1064nm infrared optical fiber laser instrument the average life of visible light source, be difficult to change.
[summary of the invention]
The technical problem to be solved in the present invention, be the pilot light generating means that a kind of fiber laser is provided, controlling frequency-doubling crystal is inserted in light path when needs laser instrument provides pilot light to locate, the exit optical when not needing to provide pilot light to locate, thus the loss and the stray light that reduce laser power.
The present invention is achieved in that a kind of pilot light generating means of fiber laser, comprise encapsulating package, and be arranged on optical fiber end cap, beam shaping telescope, free space isolator, frequency-doubling crystal and diaphragm in this encapsulating package along optical path direction successively; Described frequency-doubling crystal is arranged on a fixture, and this fixture is controlled by an insertion control device, when needs laser instrument provides pilot light to locate, described frequency-doubling crystal is inserted in described light path, and when not needing to provide pilot light to locate, described frequency-doubling crystal is exited described light path.
Further, described insertion control device is solenoid valve, and the valve body of solenoid valve connects described fixture, and this solenoid valve is controlled by a power switch be located at outside described encapsulating package.
Further, the light entrance face of described frequency-doubling crystal and exit facet are all coated with the high transmittance film of visible wavelength after the high transmittance film of described fiber laser Output of laser wavelength and frequency multiplication.
Tool of the present invention has the following advantages: frequency-doubling crystal is arranged on a fixture by the present invention, and this fixture is controlled by an insertion control device, frequency-doubling crystal is made to be inserted in light path when needs laser instrument provides pilot light to locate, the exit optical when not needing to provide pilot light to locate, thus the loss and the stray light that reduce laser power.
[accompanying drawing explanation]
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of the pilot light generating means of fiber laser of the present invention.
[embodiment]
As shown in Figure 1, the pilot light generating means of fiber laser of the present invention, comprise encapsulating package 1, and be arranged on optical fiber end cap 2, beam shaping telescope 2, free space isolator 4, frequency-doubling crystal 5 and diaphragm 6 in this encapsulating package 1 along optical path direction successively; Described frequency-doubling crystal 5 is arranged on a fixture 7, and this fixture 7 is controlled by an insertion control device 8, when needs laser instrument provides pilot light to locate, described frequency-doubling crystal 5 is inserted in described light path, and when not needing to provide pilot light to locate, described frequency-doubling crystal 5 is exited described light path.
Wherein, insertion control device 8 of the present invention is various ways, and as being solenoid valve, the valve body of solenoid valve connects described fixture, and this solenoid valve is controlled by a power switch (not shown) be located at outside described encapsulating package.When power switch is opened, because the effect of magnetic force can drive described fixture 7 to move after valve body energising, thus insert or exit described light path.
The light entrance face of described frequency-doubling crystal 5 and exit facet are all coated with the high transmittance film of visible wavelength after the high transmittance film of described fiber laser Output of laser wavelength and frequency multiplication, reduce the power attenuation of Output of laser.
Its principle of work is: export 1064nm infrared light for fiber laser, on the 1064nm laser optical path that fiber laser exports, successively by the frequency-doubling crystal 5 after optical fiber end cap 2, beam shaping telescope 3 and free space isolator 4 in fixture 7, export finally by diaphragm 6.When needs laser instrument provides pilot light to locate, by electromagnetic valve linking fixture 7, frequency-doubling crystal 5 is inserted in light path, 1064nm laser forms visible ray for location by frequency-doubling crystal 5, when not needing to provide pilot light to locate, quit work by external power switch Controlling solenoid valve, electromagnetic valve linking fixture 7, frequency-doubling crystal 5 is withdrawn from light path, thus reduces loss and the stray light of laser power.
As previously mentioned, frequency-doubling crystal is arranged on a fixture by the present invention, and this fixture is controlled by an insertion control device, frequency-doubling crystal is made to be inserted in light path when needs laser instrument provides pilot light to locate, the exit optical when not needing to provide pilot light to locate, thus the loss and the stray light that reduce laser power.
Although the foregoing describe the specific embodiment of the present invention; but be familiar with those skilled in the art to be to be understood that; specific embodiment described by us is illustrative; instead of for the restriction to scope of the present invention; those of ordinary skill in the art, in the modification of the equivalence done according to spirit of the present invention and change, should be encompassed in scope that claim of the present invention protects.
