Description
Technical field
The invention belongs to laser amplifier technical field more particularly to a kind of composite construction formula laser amplifiers.
Background technique
Currently, thin-disc laser amplifier mainly utilizes thin slice rapid heat dissipation, aperture is big, can be stronger by expanding aperture acquisition
Laser output.But the lateral gain length of thin-disc laser amplifier is always considerably larger than its thickness, lateral unwanted oscillation pole
The earth limits the output of output power.It can not achieve by increasing the method that lateral cross-sectional area promotes output power.The result is that going out
Light area or very little, 10 millimeters or so of general diameter.
The diameter of usual laser bar exports single mode, and 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, lateral gain length is greater than longitudinal gain length, it is lost caused by parasitic spontaneous radiation amplification
It is very big.In order to inhibit lateral unwanted oscillation to have taken up many methods.
Improving laser output power, core are laser particle numbers, i.e. the radiation source of generation laser is more.Laser particle number etc.
In gain media workspace cavity mold volume multiplied by doping concentration.It is that volume is the bigger the better naturally under same doping concentration.For
Laser bar can obtain more laser outputs by the increase improving laser population of the length and diameter of growth laser bar.But
It is that the source of fuel factor and large aperture material all limits the use of laser bar.Using flake structure be enlarged-area, increase dissipate
One effective way of hot surface promotion output power.
Flake structure still has heat dissipation problem, and simple solution is further thinned.Thinned and heat radiation
Two measures of ability are able to achieve lateral thermal distoftion and are reduced to the degree that can permit.But unwanted oscillation limits laser aperture
Increase, the limitation in aperture and being thinned for thickness, the total volume of laser material workspace is restricted, and as a result promotes doing for output power
Method still leans on promotion doping concentration, and the problem that doping concentration elevator belt comes is that the heat that local generates increases, and laser is caused to export
Distortion.In order to reduce thermal distoftion, realizing uniformly and quickly radiate, sheet thickness is reduced to 0.2 millimeter, and using advanced
Heat dissipation technology, but result also suffers from the puzzlement of fuel factor.And after thin slice is thinned, pump light cannot be fully absorbed and have
Effect utilizes lasing ion, needs using complicated multi-pass condenser system, to increase the complexity of system.
Junction is set to absorb transverse-vibration in order to reduce lateral unwanted oscillation amplification using the horizontally-spliced technology of laser thin slice
The laser swung, so that lateral unwanted oscillation be inhibited to amplify.For this set technology based on Germany, other countries' follow-up develops 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.Develop Yb:
YAG, doping concentration promote 11at%, and thin slice accomplishes 0.2 millimeters thick, is conducive to radiate.Using such assembling structure, use
Microchannel circulating liquid is cooling, it is heat sink on there is aperture to vacuumize, suck sheeting by atmosphere negative pressure, avoid warpage.It is promoted
By the way of round-trip multipass, Pumping mechanism is also complicated and expensive for the absorption of pump light.This set of technology has developed
It boils over, is accordingly difficult to continue to lift up laser output power.
Similar such splicing, or it is all uniform thickness that scribing line addition absorbing material, which inhibits the design of unwanted oscillation amplification,
Thin slice.This structure limits the application of transversal waveguides pump technology simultaneously.Domestic some methods pumped using transversal waveguides
It is that the YAG waveguide undoped from periphery is coupled into center disk.This method is originating from Japan.Face asking for pumping homogeneity
Topic, at present also in numerical simulation and condition test among.
The problem of another problem that large scale thin-sheet laser faces is large scale laser material.Crystalline material is due to crystalline substance
The limitation of body growing principle, is easily formed rodlike, and lateral dimension is smaller, and laser ceramics is a developing direction, but swashs
There are also to be hoisted for the performance of light ceramic.
In conclusion current high-power, high-energy thin-sheet laser and laser amplifier, still do not walk around the limit of fuel factor
System, lateral unwanted oscillation and the influence of pumping homogeneity are unable to get the laser output of high quality.
