Description
Technical field
The utility model relates to the semiconductor conicals under laser amplifier more particularly to a kind of one way and round trip composite mode
Laser amplification device.
Background technique
In the fields such as Physics of Cold Atoms research and accurate measurement, laser is a kind of essential experimental resources, and
Main operational means.One complete cold atom interferometer Experiment generally require a variety of different frequency different capacities laser or
Simultaneously or timesharing act on atom realize to atomic group complexity manipulate, can refer to document (Test of Equivalence
Principle at 10-8 Level by a Dual-Species Double-Diffraction RamanAtom
Interferometer, Zhou Lin etc., Phys.Rev.Lett. volume 115, page 013004,2015).Complete interferometer
Experiment needs a variety of different laser, such as cooling light, time pump light and Raman light.These laser frequencies are different, and right
The requirement of laser is also different, and if Raman light needs fairly good beam quality and the purity of frequency spectrum, and cooling and time pump light requires phase
To lower.
It is required to provide that the combination of commercial semiconductor lasers and semiconductor conical laser amplifier (TA) are commonly used in experiment
Laser.Commercial semiconductor lasers can provide quality and the purity of frequency spectrum all good laser, and output power is usually several
Ten milliwatts；Semiconductor conical laser amplifier is a kind of laser power amplifier part, output laser and injection laser frequency phase
Together, but output power may be up to 1 watt even 2 watts.TA is commonly used in experiment, and power amplification is carried out to meet reality to the laser after shift frequency
Test demand.However the use of TA equally has its limitation.
Usual TA work requires the power of seed laser when one way work in one way operating mode, it needs several
The seed light injection of ten milliwatts can just work normally, and amplification efficiency is lower, and the output laser of a commercial semiconductor lasers
Only it is able to satisfy the injection requirement of a TA；Furthermore multiple shift frequency is needed in experiment, and shift frequency operation will cause the damage of laser power
It loses, when especially shift frequency range arrives GHz magnitude, efficiency often only has 30% to pass through less than the output laser of, semiconductor laser
It crosses after shift frequency large-scale in this way and is unable to satisfy the injecting power demand of TA.These problems cause to generally require multiple put in experiment
The combination of big device, required laser is generated by multiple shift frequency and power amplification, and laser system had both been made to become complicated in this way,
It is not easy to optimize and integrate, also improve cost, waste a large amount of resource, and repeatedly power amplification meeting introducing portion need not
The noise wanted, influences experimental result.
Limitation for TA to incident seed light, can use the construction of round trip TA, it drops the limitation of seed optical power
Low two orders of magnitude, from tens milliwatts to several hundred microwatts, to greatly improve semiconductor conical laser amplifier
Amplification efficiency can refer to document (Double-pass tapered amplifier diode laser with an output
Power of 1Wfor an injection power of only200 μ W, V.Bolpasi etc., Rev.Sci.Instrum.
Volume 81, page 113108,2010).But in practical applications we have found that round trip TA is due to round trip competition and spontaneous emission components
Influence, Output optical power is not sufficiently stable, and the purity of frequency spectrum for exporting laser is poor, such laser can be used for it is cooling with
Pump light is returned, the place for having high request to laser, such as Raman light can not be but used.
In conclusion it is difficult to meet the needs of cold atom interferometer Experiment is to laser due to the limitation of TA itself.One way
Amplification efficiency is lower when work, and is difficult to provide the seed laser of enough power；Although amplification efficiency is high when round trip works,
It is poor to export laser activity, it can not be as high demand laser such as Raman lights.

The 1st acousto-optic modulator 4-1 under 1st radio frequency source 14-1 driving can expeditiously modulate seed light.
When 1st acousto-optic modulator 4-1 does not work, seed light frequency does not change, and direction will not deviate, will be along 0 grade of light
Direction is propagated, and the 2nd emergent light a2 is become.Due to not being modulated, the power of the 2nd emergent light a2 is larger, after coupled transfer
Power can satisfy the seed light requirement of one way TA.When 1st acousto-optic modulator 4-1 works, quarter-wave plate 5, plano-convex lens 6
It is located at+1 grade of light direction after modulation, they and the 1st acousto-optic modulator 4-1 and the 1st polarization spectro rib with the 1st reflecting mirror 7-1
Mirror 3-1 constitutes round trip acousto-optic modulator structure, can refer to document (Double-pass acousto-optic modulator
System, E.A.Donley etc., Rev.Sci.Instrum. volume 76, page 063112,2005).Round trip acousto-optic modulator knot
Structure makes seed light pass twice through the 1st acousto-optic modulator 4-1 shift frequency, and due to passing twice through quarter-wave plate 5, laser polarization
Direction changes 90 ° to be reflected by the 1st polarization splitting prism 3-1, becomes the 1st emergent light a1.The diffraction of acousto-optic modulator is imitated
The joint effect of rate and frequency modulation(PFM) by acousto-optic modulator itself and RF driving source, therefore can be according to need in practical application
It asks and neatly selects different acousto-optic modulator and radio frequency source.Emergent light a1 is used as the seed of round trip TA by coupled transfer later
Light, the demand to power is very low (only several hundred microwatts), therefore even if using the lower high frequency acousto-optic modulator of diffraction efficiency,
It can meet demand.
1st emergent light a1 passes through the 1st fibre-coupled mirrors 8-1, the 1st after the 3rd half wave plate 2-3 adjusts polarization
The coupling input of single-mode polarization maintaining fiber 9-1, the 2nd fibre-coupled mirrors 8-2, are propagated and coupling is output into the 1st seed light a3；It is similar
, the 2nd emergent light a2 is in the 2nd half wave plate 2-2, the 3rd fibre-coupled mirrors 8-3, the 2nd single-mode polarization maintaining fiber 9-2 and the 4th light
Become the 2nd seed light a4 under the action of fine coupling mirror 8-4.
Seed light of the 1st seed light a3 as round trip TA, with the 2nd polarization splitting prism 3-2, Faraday polarization apparatus 10, lattice
Blue Taylor prism 11, the 6th half wave plate 2-6, semiconductor conical laser amplifier 12, optical filter 13 and the 2nd reflecting mirror 7-2
Constitute round trip TA structure.1st seed light a3 is after the 4th half wave plate 2-4 adjustment polarization by the 2nd polarization splitting prism
3-2 reflection has rotated 45 ° by its polarization direction after Faraday polarization apparatus 10, and adjustment Glan-Taylor prism 11 to polarize
Laser after rotation can be transmitted through, and the 6th half wave plate 2-6 then put with semiconductor conical laser by adjustable laser
The polarization of big device 12 is overlapped, and hereafter laser obtains first time power amplification back through TA.2nd radio frequency source 14-2 controls the 2nd
The working condition of acousto-optic modulator 4-2, when TA is in round trip working condition, radio frequency source is turned off, and acousto-optic modulator does not work, right
Light channel structure does not influence substantially.Optical filter 12 can filter out the stray light due to the spontaneous radiation generation of TA.Reversed amplification
For laser afterwards by being reflected after the 2nd acousto-optic modulator 4-2 by the 2nd reflecting mirror 7-2, forward direction realizes that the second journey is put by TA
Greatly.The output light of forward direction amplification passes sequentially through the 6th half wave plate, Glan-Taylor prism 11, Faraday polarization apparatus 10 and the 2nd
Polarization splitting prism 3-2.Since again by Faraday polarization apparatus 10, laser polarization direction 45 ° of rotation again is final defeated
The polarization direction of light has rotated 90 ° compared with the 1st seed light out, thus is transmitted through the 2nd polarization splitting prism 3-2, becomes defeated
Light a5 out.Here the 2nd polarization splitting prism 3-2, Faraday polarization apparatus 10 and Glan-Taylor prism 11 have effectively formed isolation
The construction of device, isolation are influenced by the extinction ratio of the angle of Faraday polarization apparatus 10 and two prisms.
2nd seed light a4, the 5th half wave plate 2-5, the 2nd acousto-optic modulator 4-2 and semiconductor conical laser amplifier
12 constitute one way TA structure.The 2nd radio frequency source 14-2 is opened under one way TA operating mode, and the 2nd acousto-optic modulator 4-2 is in work shape
State, the 2nd seed light is after the 5th half wave plate 2-5 adjustment polarization matches with TA, by the 2nd acousto-optic modulator 4-2,
Its+1 grade of light forward direction passes through TA and obtains power amplification.It is safe that its shoot laser equally passes through the 6th half wave plate 2-6, Glan
Output light a5 is formed after strangling prism 11, Faraday polarization apparatus 10 and the 2nd polarization splitting prism 3-2.
The one way and round trip operating mode of TA is by two radio frequency source control switchings.When the 1st radio frequency source 14-1 shutdown while the 2nd
When radio frequency source 14-2 is opened, the 1st acousto-optic modulator 4-1 does not work and the 2nd acousto-optic modulator 4-2 works, at this time semiconductor laser
The seed light of device is propagated all along the 2nd emergent light a2, and the 1st emergent light a1 is closed, i.e., only the 2nd seed light a4 is without the 1st kind
Sub-light a3, TA are in simple one way operating mode；When the 1st radio frequency source 14-1 opens the 2nd radio frequency source 14-2 closing simultaneously, the
1 acousto-optic modulator 4-1 work, the 2nd acousto-optic modulator 4-2 do not work；Since acousto-optic modulator has certain extinction ratio, i.e., the 1st
0 grade of light direction of acousto-optic modulator 4-1 has fraction of laser light power, and the 1st emergent light a1 and the 2nd emergent light a2 is deposited simultaneously at this time
That is, the 1st seed light a3 and the 2nd seed light a4 have；But since the 2nd acousto-optic modulator 4-2 is in off position, the 2nd kind
Sub-light a4 can not diffraction enter TA, therefore TA is in simple round trip working condition at this time.The benefit manipulated in this way is two kinds of works
Make to have under state and only one seed light enters TA, guarantees that TA is in simple one way or round trip working condition without going out
The case where now interfering with each other.
The Output optical power stability and laser purity of round trip TA is all relatively poor, the stability and laser purity of one way TA
Very well, can distribute according to need single round trip operating mode in actual work, export laser as round trip may be selected in cold atom interferometer
Cold atom cloud is prepared with time pump light as cooling, one way output laser is selected as Raman light and carries out interference experiment.
The utility model can meet a variety of laser demands in cold atom interferometer Experiment, provide a kind of one way and round trip
Semiconductor conical laser amplifier system under composite mode is put using a semiconductor laser and a semiconductor conical laser
Big device achieves that required laser output, greatly simplification are integrated with cold atom interferometer Experiment laser optical path；Utilize the time-division
Advantage under the faster switching characteristics of multiplexing technology and two kinds of different working modes is complementary, which can be with time-sharing work in difference
Mode, can both export High-performance lasers, and the high efficiency amplification of laser power also may be implemented.
