Description
Technical field
The invention belongs to laser amplifier technical field, more particularly to a kind of composite construction formula laser amplifier.
Background technology
At present, thin-disc laser amplifier mainly utilizes thin slice rapid heat dissipation, and aperture is big, can obtain stronger by expanding aperture
Laser is exported.But the horizontal gain length of thin-disc laser amplifier is always considerably larger than its thickness, horizontal unwanted oscillation pole
The earth limits the output of power output.Method by increase lateral cross-sectional area lifting power output can not be realized.Result is
Light area or very little, the millimeter of general diameter 10.
The diameter output single mode of usual laser bar, diameter only has several millimeters.With thin-disc laser ceramics, it is desirable to by wafer diameters
Accomplish 10 to 20 centimetres.As a result, horizontal gain length is more than longitudinal gain length, the loss for causing is amplified in parasitic spontaneous radiation
It is very big.Many methods have been had taken up in order to suppress horizontal unwanted oscillation.
Improving laser power output, core is laser particle number, that is, produce the radiation source of laser many.Laser particle number etc.
In gain media workspace chamber, model volume is multiplied by doping concentration.Naturally it is that volume is the bigger the better under same doping concentration.For
Laser bar, can obtain more laser outputs by increasing the length of laser bar and the increase improving laser population of diameter.But
It is that the source of fuel factor and large aperture material all limits the use of laser bar.It is enlarged-area using flake structure, increases scattered
Hot surface lifts an effective way of power output.
Flake structure is still present heat dissipation problem, and simple solution is further thinning.Thinning and heat radiation
Two measures of ability can realize that horizontal thermal distoftion is reduced to the degree that can be allowed.But unwanted oscillation limits laser aperture
Increase, the limitation in aperture and thickness it is thinning, the cumulative volume of laser material workspace is restricted, and as a result lifts doing for power output
Still by lifting doping concentration, the problem that doping concentration elevator belt comes is that the heat that local is produced increases to method, causes laser to export
Distortion.In order to reduce thermal distoftion, realize uniform and quickly radiate, sheet thickness is reduced to 0.2 millimeter, and using advanced
Heat dissipation technology, but as a result also suffer from the puzzlement of fuel factor.And after thin slice is thinning, pump light can not be fully absorbed and had
Effect utilizes lasing ion, it is necessary to lead to condenser systems using baroque, so as to increased the complexity of system more.
Amplify to reduce horizontal unwanted oscillation, using the horizontally-spliced technology of laser thin slice, junction is absorbed transverse-vibration
The laser for swinging, so as to suppress horizontal unwanted oscillation amplify.Based on Germany, other countries' follow-up develops this set technology to this set technology
It is fewer.The thin-sheet laser nearly more than ten years of Germany's development all play leading position in solid state laser development.Development Yb:
YAG, doping concentration lifting 11at%, thin slice accomplishes 0.2 millimeters thick, is conducive to radiating.Such assembling structure is employed, is used
The cooling of microchannel circulating liquid, it is heat sink on there is aperture to vacuumize, suck sheeting by atmosphere negative pressure, it is to avoid warpage.Lifting
The absorption of pump light employs the mode of round multipass, and Pumping mechanism is also complicated and expensive.This set of technology has developed
Boil over, be accordingly difficult to continue to lift up laser output power.
Similar such splicing, or the design that line addition absorbing material suppression unwanted oscillation is amplified all is uniform thickness
Thin slice.This structure limits the application of transversal waveguides pump technology simultaneously.It is domestic some using transversal waveguides pumping method
It is to be coupled into center disk from the YAG waveguides of periphery undoped.This method originates from Japan.Face asking for pumping homogeneity
Topic, at present also in numerical simulation and condition test among.
Another problem that large scale thin-sheet laser faces is the problem of large scale laser material.Crystalline material is due to crystalline substance
The limitation of body growing principle, is easily formed bar-shaped, and lateral dimension is smaller, and laser ceramics is a developing direction, but swashs
The performance of light ceramic is also to be hoisted.
In sum, current high-power, high-energy thin-sheet laser and laser amplifier, still do not walk around the limit of fuel factor
System, horizontal unwanted oscillation and the influence of pumping homogeneity, it is impossible to obtain high-quality laser output.
