With, it is achieved removing space junk is a kind of feasible scheme.At present, similar system is essentially all adopts
With a set of laser transmitting system, a branch of superlaser is transmitted in target.This laser action system, except
Outside the performance impact of laser instrument self, the eyeglass expanded in light path that Stimulated Light is irradiated can produce temperature deformation,
The outgoing beam quality making system does not reaches the performance indications of optimum；Additionally laser arrives target through propagation in atmosphere,
Atmospheric turbulance can make laser produce distortion, and the atmospheric heat halo effect of propagation of intense laser beam also can cause laser abnormal
Become, thus cause the laser power on fragment target uneven or decline, have a strong impact on the usefulness of system.Pin
To the problems referred to above, current reasonable solution is introducing adaptive optical technique in laser transmitting system,
Realize laser beam reshaping to correct with propagation in atmosphere.
In order to realize preferable space junk removal effect, it is desirable to arrive the laser power density on fragment enough
Greatly.On the one hand this can increase the power of emitting laser；On the other hand the mouth of transmitter-telescope can be increased
Footpath, after making employing adaptive optical technique, sufficiently small close to diffraction limited spot on space junk.But
It is, after simple increase power is higher to the requirement of laser technique, and laser power increases, light path system
Optical element temperature deformation in system can become to be difficult to control to, and has a strong impact on outgoing beam quality；And increase and send out
Penetrate telescopical bore then telescope technology to be had higher requirement, corresponding adaptive optics scale
Also can strengthen, what these all can increase system realizes difficulty and cost.
Summary of the invention
