The present mature High Power Femtosecond Laser of technology, form discharge channel because atmosphere can be punctured (making air generation ionization), successfully be used for the lightning lead-in and arresting operation now, Chinese patent 93204289 " rotary laser lightning lead-in and arresting device " discloses and has utilized the laser breakdown air to make air ionization form the technology that discharge channel comes lightning lead-in and arresting.But if femtosecond laser is used for using as the high-octane occasion of needs such as weapon, because of its energy too little (though its power reaches the several times of the existing generating in whole world gross power, but the also not enough erg-ten of gross energy of each emission), almost be worth without any (operation).
Three, summary of the invention:
The present invention utilizes electric energy to strengthen the energy of laser.Particular content is:
High-energy laser of the present invention is made up of high power laser light generator and electrode.The high power laser light generator can use the existing laser that sends can make the superpower laser of air ionization (as the High Power Femtosecond Laser device); Electrode is positioned over the exit that laser generator sends laser, generally also has an aperture in the centre of electrode, and laser can pass through from the middle aperture or the limit of electrode.After connecting high-tension electricity (as electrode is received the positive pole of high energy high-voltage capacitor that is full of electricity or the output of high-tension transformer by lead) to electrode, make high power laser light (reaching the femtosecond laser of terawatt (TW) level as power) that laser generator sends from the high voltage electric field that electrode produces by penetrating.High power laser light can puncture air makes air ionization produce a conductive channel, (as target ground connection or with electrode discharge loop is arranged) when discharging condition possesses, and this will be produced discharge (lightning) and be discharged huge energy by the conductive channel that laser produces.The sound wave energy of powerful electric current, electromagnetic pulse and discharge generation produces destruction to target, and it is the same that execution is subjected to thunderbolt just like target.If target does not have ground connection, also can be when penetrating high potential laser (i.e. the laser that from the electric field that high-potential electrode produces, passes through), ground connection laser (i.e. the laser that from low-potential electrode or grounding electrode, passes through) from another high-energy laser ejaculation electronegative potential, form discharge loop, the generation lightning smashes target or target is damaged.
The present invention is because utilization discharge electric energy strengthens the energy of laser, and the size of discharge electric energy energy depends on discharge power supply energy stored size.According to existing technical merit, the energy of manual discharge can surpass the energy of natural thunder and lightning, the energy of existing high power (femtosecond) laser is brought up to more than 1000 to 1 megajoules from not enough erg-ten, and energy has just improved 1000 to 1,000,000 times, even higher.
The appearance of high-energy laser of the present invention, the greatly scope of application of expansion of laser light:
Use as laser weapon, it has that target of attack speed is fast, the shift of fire is fast, efficiency-cost ratio high (each launching costs is compared almost and can be ignored with aircraft or cost-per-bird), killing-efficiency advantages of higher, can smash targets such as aircraft, guided missile in moment, thereby make laser weapon enter the practical stage; Can destroy electronic equipment, electric power facility, puncture and light petroleum pipeline, make fire on the enemy innerland, the enemy be carried out the precision strike of operation formula; Can be used to shoot living aims such as enemy's human body, it " is electrocuted ".
Except as the weapon purposes, also can be used for machining (similar), plant deinsectization (but light, electricity, sound desinsection of producing during lightning) and apply fertilizer that (airborne nitrogen becomes nitrogen dioxide with the oxidation symphysis during lightning in operation with existing laser, edm process.The nitrogen dioxide that generates is dissolved in and becomes the very low nitric acid of concentration in the water.It one is fallen in the soil, just with other material chemical combination, becomes nitre, and nitre is good chemical fertilizer.)
Also be used in the artificial lightning of aerial manufacturing in addition: when the charged laser of the one high and one low current potential of two bundles is collided, will form discharge loop and produce lightning aloft.Aerial like this lightning flashes and thunder rumbles will no longer be the masterpiece of the Nature, and human use's oneself ability produces grand " thunder and lightning " in also can be on high.Artificial lightning can be used for fertilising, desinsection, decorate the night sky, also can provide new technological means in addition in the basic research in fields such as physics, chemistry, optics, electricity, nuclear fusion igniting.
