Background technology
In high power solid state laser system, to be only partially converted into laser defeated for the pump light that laser gain medium absorbs
Go out, remaining overwhelming majority is converted to waste heat and is deposited on inside gain media, heat distribution heterogeneous is formed, with double-end pumping
For plate solid laser, decayed when pump light transmits in the gain medium by exponential form by absorption, therefore along plate
The distribution of length direction endogenous pyrogen is approximately gentle " V " type.Since solid state gain medium can only rely on non-pumped outer surface
Heat is taken away in cooling, and the cooling of internal heat and outer surface necessarily forms temperature gradient inside gain media, corresponding to produce
Raw thermal stress and thermal strain and the change of gain media refractive index eventually lead to the reduction of laser output power and light beam matter
The decline of amount.In the development course of laser, fuel factor problem is always to restrict laser to ultra high power and quality light beam

Periodically, the total heat transfer coefficient of fluid is inversely proportional amount one with channel hydraulic diameter in rectangular channel, therefore, with subtracting for channel diameter
Small, the coefficient of heat transfer increases.
At present, the equivalent diameter of high power solid state laser microchannel cooling heat sink is generally between 0.1mm~0.4mm,
Increasingly being promoted for laser output power proposes higher requirement to the cooling efficiency of micro-channel heat sink, further reduces
Cooling heat sink equivalent diameter is likely to result in the blocking of channel, and cooling efficiency will not be significantly increased, therefore only by subtracting
The hydraulic diameter of passage aisle can not meet the cooling requirement of laser.To improve the cooling efficiency of micro-channel heat sink, need
The complicated flow passage structure of inside microchannels setting is with further thinned flow boundary layer or in the cooling for flowing through micro-channel heat sink
High thermal conductivity coefficient particle is added in medium to improve the thermal conductivity factor of cooling medium, but complicated flow passage structure development cost
Height, difficulty of processing are big, it is difficult to produce manufacture in enormous quantities, and often be made after cooling medium summarizes addition high thermal conductivity coefficient particle
Into the blocking of microchannel, and then make entire heat sink cooling failure.Widely used structure in superpower laser cooling scheme at present
Simplest parallel groove shape or needle ribbed micro-channel heat sink, still increase substantially its cooling efficiency without preferable mode,
And its internal simple runner can not be distributed with the heat of " V " type approximate inside laser gain medium and match.
