Description
Technical field
The present invention relates to a kind of optical path adjusting system, particularly relate to a kind of light laser target practice optical path adjusting system and method based on LabVIEW.
Background technology
Along with the development of ultrashort ultra-strong femto-second laser technology, the peak power of ultrashort and ultrahigh laser device has reached terawatt (TW) (TW, 1TW=10
12w) or even clap watt (PW, 1PW=10
15w) magnitude, by optical focus technology, its peak power density can arrive relativity magnitude (10
18w/cm
2), this provides real basis for light laser drives target to produce relevant radiation source (also can be described as secondary source, as feature K α x-ray source, BetatronX radiographic source, high energy proton source etc.).For obtaining the radiation source of high-quality, for ensureing effective utilization of laser energy, the experiment that most light laser drives target to produce various secondary source is all launch under vacuum conditions, and vacuum level requirements is 10
-3pa is even higher, but under vacuum environment, the fine adjustment of light path accounts for the most of the time, is also to determine one of Success in Experiment whether key factor, and therefore, the stable and fine adjustment of light path is most important under vacuum conditions.
At present, the method for the most conventional light laser target practice optical path adjusting is divided into following process: 1) stand for optical lens be arranged on electricity driving displacement platform, under atmospheric environment, complete adjustment; 2) do a target cross with reflector, be adjusted to hot spot and beat central point at reflector target cross, this point is facula position anchor point; 3) utilize mechanical pump, molecular pump, cryopump etc. that the vacuum chamber air pressure residing for stand for optical lens is evacuated to 10 successively
-3about Pa; 4) directly observed by human eye or ccd image display after eye-observation hot spot in the position of reflector target cross, manually inching button (inching button is the platform courses handle that producer joins) regulates electricity driving displacement platform, realize to light path point to fine setting.This method has the following disadvantages: after 1) vacuumizing, and causes light path to offset due to the change of laser propagation medium refraction index, cannot realize monitoring in real time and regulate translation stage to correct light path under vacuum; 2) adopt inching button control, during for mobile designated displacement amount operating cost, in addition, even if the software kit that developer gives also can only control a particular dimension translation stage, function singleness and operation inconvenience, the request for utilization of complication system can not be met; 3) judge that hot spot carrys out location spot in the position of reflector and whether offsets by human eye, there is human eye error, and the repetition frequency of laser being 10Hz or lower, there is difficulty in eye-observation; 4) high-precision flat moving stage is generally all import equipment, belongs to common apparatus, and the single and function imperfection of mode of operation, can not meet the complex environment request for utilization of specifying; 5) be directed to light laser experiment, light path is complicated, and regulate dimension many, control difficulty large, interface is complicated, and software kit can not meet the demands.
In addition, follow-up work of the present invention is that light laser target practice produces x-ray source, needing is the circular light spot within the circular light spot of 30mm is focused to diameter 10 μm by diameter, can hot spot finally focus within 10 μm, whether stablizing of light path is most important, because light path is very large on OAP impact, if light path offsets, hot spot focuses on less than 10 μm after OAP, or the shape of hot spot is not circular, hot spot is bigger than normal and light spot shape is bad, and the power density size that final hot spot acts on target material surface is also different, and physical phenomenon just has very big-difference.
