Description
Przedmiotem wynalazku jest uklad sterowania parametrami wiazki promieniowania laserowego w oparciu o model matematyczny.The subject of the invention is a system for controlling the parameters of a laser beam based on about a mathematical model.
Dotychczas znane uklady zasilania i sterowania praca lasera pozwalaja jedynie na sterowanie jednym para¬ metrem promieniowania laserowego, to jest energia impulsu przy impulsowej pracy lasera lub moca promieniowa¬ nia laserowego przy ciaglej pracy lasera. Uklady te sa ukladami otwartymi bez sprzezenia zwrotnego i nie pozwalaja na niezalezne sterowanie wielkoscia energii impulsu lasera i czasu trwania impulsu oraz nie umozliwiaja sterowania praca lasera w oparciu o model matematyczny.Hitherto known power supply and control systems for laser operation allow for controlling only one pair meter of laser radiation, that is, the pulse energy in pulsed operation of the laser or the radiation power operation of the laser during continuous operation of the laser. These circuits are open circuits without feedback and not allow for independent control of the amount of laser pulse energy and the duration of the pulse, and do not allow laser control based on a mathematical model.
Celem wynalazku jest usuniecie tych niedogodnosci przez opracowanie ukladu pozwalajacego na niezalezne sterowanie podstawowymi parametrami wiazki promieniowania laserowego w oparciu o model matematyczny.The object of the invention is to overcome these drawbacks by providing a system that is independent control of the basic parameters of a laser beam based on a mathematical model.
Cel ten uzyskano dzieki skonstruowaniu ukladu sterowania wedlug wynalazku, który pozwala na niezalezne sterowanie energii impulsu laserowego i czasu jego trwania w oparciu o model matematyczny.This object is achieved by designing a control system according to the invention which is independent control of the laser pulse energy and its duration based on a mathematical model.
Istota ukladu wedlug wynalazku jest to, ze sklada sie on z kolejno zabudowanych zespolów, zasilacza sterowanego, wzbudzania laserowego, osrodka laserujacego, regulacji dobroci rezonatora, skupiajacego wiazke laserowa i zwiazanego z powierzchnia absorbujaca promieniowanie laserowe, polaczonych z zespolem steruja¬ cym, który steruje tymi zespolami oraz czlonami wykonawczymi, przy czym wyjscia wszystkich zespolów sa polaczone poprzez zespoly pomiarowo-przetwarzajace dane z komputerem sterujacym zespolem sterowania w ukladzie zamknietym sprzezenia zwrotnego.The essence of the system according to the invention is that it consists of sequentially built-up units, a power supply controlled, laser excitation, laser center, goodness adjustment of the resonator, focusing the beam laser and associated with the surface absorbing laser radiation, connected to the control unit which controls these assemblies and executive members, the outputs of all assemblies being connected by measuring and data processing units with the computer controlling the control unit in closed feedback loop.
Uklad wedlug wynalazku dzieki temu, ze zawiera zasilacz sterowany, zespól regulacji dobroci rezonatora, zespól skupiajacy wiazke laserowa i zespól zwiazany z powierzchnia absorbujaca promieniowanie laserowe, po¬ zwala na swiadome, zadane ksztaltowanie przestrzenno-czasowych parametrów wiazki laserowej i automatyczna kontrole parametrów wyjsciowych wszystkich zespolów ukladu, .o umozliwia automatyczne sterowanie proce¬ sem akcji laserowej za pomoca komputera w oparciu o model matematyczny.The system according to the invention, due to the fact that it includes a controlled power supply, a goodness adjustment unit of the resonator, unit focusing the laser beam and the unit associated with the surface absorbing laser radiation, allows for conscious and automatic shaping of the space-time parameters of the laser beam control of the output parameters of all components of the system, .o enables automatic control of the processes laser action semester using a computer based on a mathematical model.
Przedmiot wynalazku jest przedstawiony w przykladzie wykonania na zalaczonym rysunku, który przed¬ stawia schemat blokowy ukladu.97 672 Uklad sklada sie z kolejno po sobie zabudowanych zespolów zasilacza sterowanego 1, wzbudzania lasera 2, osrodka laserujacego 3, regulacji dobroci rezonatora 4, skupiajacego wiazke laserowa 5 i zwiazanego z powierzen- nia absorbujaca promieniowanie laserowe 6, polaczonych z zespolem sterujacym 7, który steruje zespolami 1-6 oraz czlonami wykonawczymi a—n. Wyjscia zespolów 1-6 sa polaczone poprzez zespoly 8—12 pomiarowo-prze- twarzajace dane, z komputerem 13 sterujacym zespolem sterowania 7.The subject matter of the invention is illustrated in an exemplary embodiment in the attached drawing, which is illustrated by creates a block diagram of the system 97 672 The system consists of successively built-in units of a controlled power supply 1, laser excitation 2, laser center 3, goodness regulation of the resonator 4, focusing the laser beam 5 and related to the surfaces absorbing laser radiation 6, connected with a control unit 7, which controls units 1-6 and executive members a-n. The outputs of sets 1-6 are connected through the sets 8-12 measuring and transferring generating data, with the computer 13 controlling the control unit 7.
Sterowanie parametrami wiazki promieniowania laserowego za pomoca ukladu wedlug wynalazku, odbywa sie nastepujaco. Energia elektryczna doprowadzona do zasilacza sterowanego 1 w zaleznosci od informacji otrzy¬ manej z zespolu sterujacego 7, jest dostarczana do zespolu wzbudzenia laserowego 2, w którym nastepuje wzbu¬ dzenie energii powodujacej powstanie akcji laserowej w zespole 3. Wychodzaca wiazka promieniowania laserowe¬ go z zespolu 3 jest regulowana w czasie w zespole regulacji dobroci rezonatora 4, jest ksztaltowana przestrzennie w zespole skupiajacym wiazke laserowa 5 i doprowadzana do zespolu zwiazanego z powierzchnia absorbujaca promieniowanie laserowe 6. Na wyjsciach zespolów 1-6 zabudowane sa zespoly 8-12 pomiarowo-przetwarzaja- ce dane, które wysylaja informacje do komputera 13. Komputer po porównaniu warunków zewnetrznych modelu matematypznego z informacjami dostarczonymi z zespolów 8-12, wysyla odpowiednie informacje do zespolu sterawania 7, który steruje oddzielnie praca poszczególnych zespolów 1—6 jak równiez moze spowodo¬ wac zadzialanie poszczególnych czlonów wykonawczych a-n realizujacych inne cele niz generacja promieniowa¬ nia laserowego.The control of the parameters of the laser beam by means of the system according to the invention takes place as follows. Electricity supplied to the power supply 1 controlled depending on the information received from the control unit 7, is supplied to the laser excitation unit 2, in which the excitation takes place energy generating the laser action in group 3. Outgoing beam of laser radiation it from the unit 3 is time-controlled in the Q factor of the resonator 4, it is spatially formed in the unit focusing the laser beam 5 and led to the unit associated with the absorbing surface laser radiation 6. At the outputs of units 1-6 there are units 8-12 measuring and processing data that sends information to the computer 13. Computer after comparing the external conditions the math model with the information supplied from sets 8-12, sends the relevant information to of the control unit 7, which separately controls the operation of the individual units 1-6, as well as may cause what is the action of individual A-n actuators realizing goals other than radiation generation laser technology.
