Description
Technical field
The utility model belongs to laser technology field, more particularly to a kind of microsphere laser device based on sun optical pumping.
Background technology
In recent years, laser and its application are developed rapidly, and microsphere laser utensil has small volume, Low threshold, transformation efficiency high
The advantages of, got the attention in scientific research.Solar energy is pure regenerative resource, effectively exploits and utilize the sun
There can be very great meaning.At present, for solar energy utilization it is most commonly used be solar water heater and solar energy
Generate electricity.Its Land use systems has optical and thermal to convert and optical-to-electronic conversion, and light-light can be directly realized by using solar energy as pumping source and is turned
Change.Because sunshine is disorderly and unsystematic and frequency spectrum is wider so can be by rambling sunshine using solar energy as pumping source
It is converted into the preferable laser of monochromaticjty.Pumping source using sunshine as laser is realized that the method for laser output has and run into
This low, pollution-free, advantages of simple structure and simple.
The content of the invention
The utility model is in view of the shortcomings of the prior art, it is proposed that a kind of microsphere laser device based on sun optical pumping.
The utility model includes two condenser lenses and an Er-doped fiber with Er-doped fiber microballoon, a diameter of 5-100
Centimetre condenser lens perpendicular to incident sunshine;The Er-doped fiber lower end of taper carries a diameter of 50-300 microns of er-doped
Fiber optic microsphere, the Er-doped fiber microballoon is positioned over the focal position of the condenser lens;A diameter of 5-10 centimetres of condenser lens is put down
Row is placed in sunshine, and close to Er-doped fiber microballoon;Sunshine medium wavelength falls light near 980nm or 1480nm as mixing
The pump light of erbium fiber optic microsphere, light produces the laser near 1550nm after the amplification of Er-doped fiber microballoon.
The utility model is applied to fiber optic microsphere field of laser device technology, and sunshine is applied to the pumping source of laser,
Microballoon is used as resonator, and Er-doped fiber microballoon is used as gain media, constructs a kind of microsphere laser device based on sun optical pumping.
Sunshine is disorderly and unsystematic and frequency distribution wider range, so the utility model can be converted to rambling sunshine
The good laser of monochromaticjty.Pumping source using solar energy as laser has simple in construction, low cost, free of contamination advantage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 be the utility model embodiment in microsphere laser device laser output spectrum figure is realized based on sun optical pumping.
Embodiment
As shown in figure 1, the utility model includes the Er-doped fiber 2 of taper, there is a diameter L its lower end(100 microns)'s
Er-doped fiber microballoon 3, Er-doped fiber microballoon is processed on the basis of the Er-doped fiber of taper and belongs to existing mature technology;From one
Individual diameter D(20 centimetres)Condenser lens 1 and a diameter of d(5 centimetres)Condenser lens 4.By diameter D(20 centimetres)Focusing it is saturating
Mirror 1 is perpendicular to incident parallel sunshine;The Er-doped fiber microballoon 3 of the lower end of Er-doped fiber 2 of taper is positioned over diameter D(20
Centimetre)Condenser lens 1 focal position so that parallel incident solar light focusing is in Er-doped fiber microballoon 3;By a diameter of d
(5 centimetres)Condenser lens 4 placed parallel to sunshine, and close to Er-doped fiber microballoon 3, so as to collect from Er-doped fiber microballoon
3 laser sent;Spectroanalysis instrument 5, which is used to measure, passes through a diameter of d(5 centimetres)Condenser lens 4 collect Er-doped fiber it is micro-
Ball laser.
The wave-length coverage of sunshine is between 300~2500nm, and its wavelength falls light near 980nm or 1480nm can be with
It is used as the pump light of Er-doped fiber microballoon.Erbium ion on Er-doped fiber microballoon, the erbium ion when being not affected by the excitation of sunshine
In low-lying level, after the irradiation of sunshine, erbium ion absorbs the energy of photon, and high level is transitted to from low-lying level, so that
So that the population on high level is more than the population of low-lying level, population inversion is realized, the erbium ion of high level is then in
Produce stimulated radiation and transit to low-lying level while launching one and the identical photon of external photon, so as to increase from high level
The quantity of sunshine photon is added.After light is incident, the light wave being coupled into microballoon can constantly occur on the surface of microballoon
Total reflection, constantly detours, 980nm or 1480nm light is put by Er-doped fiber microballoon in sunshine along the equator of microballoon
The laser near 1550nm is just generated after big, Fig. 2 is seen.
The utility model mainly make use of the light near sunshine medium wave a length of 980nm and 1480nm as er-doped material
Pumping, using Low threshold fiber optic microsphere as laser structure, it is achieved thereby that laser output of the wavelength near 1550nm.Due to
Sunshine is pure regenerative resource, and the pumping source using solar energy as laser is by rambling natural light by amplifying
The good laser of monochromaticjty is converted to afterwards, has the advantages that operating cost is low, is particularly suitable for outer space laser application.
