Taolo ea maqhubu a pulse eatheknoloji ea laser pulse control

1. Khopolo ea Pulse frequency, laser pulse Rate (Pulse Repetition Rate) e bolela palo ea laser pulses e hlahisoang ka nako ea unit, hangata Hertz (Hz). Li-pulse tsa maqhubu a phahameng li loketse ts'ebeliso ea sekhahla se phahameng sa ho pheta-pheta, athe maqhubu a tlase a loketse mesebetsi e phahameng ea matla a le mong.

2. Kamano lipakeng tsa matla, bophara ba pulse le frequency Pele ho taolo ea maqhubu a laser, kamano lipakeng tsa matla, bophara ba sekhahla le maqhubu a tlameha ho hlalosoa pele. Ho na le tšebelisano e rarahaneng lipakeng tsa matla a laser, frequency le pulse wide, 'me ho lokisa e 'ngoe ea li-parameter hangata ho hloka hore ho nahanoe ka liparamente tse ling tse peli ho ntlafatsa phello ea ts'ebeliso.

3. Mekhoa e tloaelehileng ea ho laola maqhubu a pulse

a. Mokhoa oa taolo oa kantle o jara lets'oao la maqhubu kantle ho phepelo ea motlakase, 'me o lokisa maqhubu a laser pulse ka ho laola maqhubu le potoloho ea mosebetsi oa lets'oao la ho laela. Sena se lumella pulse ea tlhahiso hore e hokahane le lets'oao la mojaro, e etsa hore e tšoanelehe bakeng sa lits'ebetso tse hlokang taolo e nepahetseng.

b. Mokhoa oa ho laola ka hare Letšoao la ho laola maqhubu le hahiloe ka har'a motlakase oa koloi, ntle le ho kenya letsoho ka ntle ho tsoa. Basebedisi ba ka khetha pakeng tsa maqhubu a tsitsitseng a hahelletsoeng ka hare kapa maqhubu a taolo a kahare a feto-fetohang bakeng sa ho tenyetseha ho hoholo.

c. Ho fetola bolelele ba sehlahisoa kapamochine oa motlakase oa motlakaseLitšobotsi tsa maqhubu a laser li ka fetoloa ka ho fetola bolelele ba resonator kapa ho sebelisa electro-optical modulator. Mokhoa ona oa taolo ea maqhubu a phahameng hangata o sebelisoa lits'ebetsong tse hlokang matla a mahareng a phahameng le bophara bo khuts'oane ba pulse, joalo ka laser micromachining le imaging ea bongaka.

d. Acousto optic Modulator(AOM Modulator) ke sesebelisoa sa bohlokoa bakeng sa taolo ea maqhubu a maqhubu a theknoloji ea laser pulse control.AOM Modulatore sebelisa phello ea acousto optic (ke hore, khatello ea mochini oa oscillation ea leqhubu la molumo e fetola index ea refractive) ho fetola le ho laola lebone la laser.

4. Theknoloji ea ho feto-fetoha ha intracavity, ha e bapisoa le ho feto-fetoha ha ka ntle, ho feto-fetoha ha intracavity ho ka hlahisa matla a phahameng ka katleho, matla a holimo.laser ea pulse. Tse latelang ke mekhoa e mene e tloaelehileng ea intracavity modulation:

a. Fumana Switching ka ho potlakisa modulating mohloli oa pompo, phaello ea mahareng palo ea phatsa ho kheloha le ho fumana coefficient li thehoa ka potlako, ho feta sekhahla sa mahlaseli a kotsi, se fellang ka keketseho e matla ea photons ka cavity le ho hlahisa laser e khutšoanyane ea pulse. Mokhoa ona o tloaelehile ka ho khetheha ho li-lasers tsa semiconductor, tse ka hlahisang li-pulses ho tloha ho nanoseconds ho ea ho mashome a picoseconds, ka sekhahla sa ho pheta-pheta ha li-gigahertz tse 'maloa,' me e sebelisoa haholo tšimong ea puisano ea optical e nang le litekanyetso tse phahameng tsa phetisetso ea data.

Q switch (Q-switching) Q switch e hatella maikutlo a optical ka ho hlahisa tahlehelo e kholo ka har'a sekoti sa laser, e lumellang ts'ebetso ea ho pompa ho hlahisa phetoho ea palo ea batho ho feta moeli, ho boloka matla a mangata. Ka mor'a moo, tahlehelo ea sekoti e fokotsehile ka potlako (ke hore, boleng ba Q ba sekoti bo eketsehile), 'me maikutlo a optical a buloa hape, e le hore matla a bolokiloeng a lokolloe ka mokhoa oa li-pulses tse matla haholo.

c. Mode Locking e hlahisa li-pulse tse khutšoane haholo tsa boemo ba picosecond kapa esita le femtosecond ka ho laola kamano ea mohato lipakeng tsa mekhoa e fapaneng ea longitudinal ka har'a sekoti sa laser. Theknoloji ea ho notlela mokhoa o arotsoe ka mokhoa oa ho notlela feela le ho notlela mokhoa o sebetsang.

d. Cavity Dumping Ka ho boloka matla a photon ka resonator, ho sebelisa seipone se nang le tahlehelo e tlaase ho tlama li-photon ka katleho, ho boloka boemo bo tlaase ba tahlehelo ka har'a cavity ka nako e itseng. Ka mor'a potoloho e le 'ngoe ea ho ea le ho khutla, molumo o matla oa "pulse" o "lahleloa" ka ntle ho lesoba ka ho fetola kapele karolo ea ka hare ea cavity, e kang modulator ea acousto-optic kapa shutter ea electro-optic, 'me laser e khutšoanyane ea pulse e ntšoa. Ha ho bapisoa le Q-switching, ho ntša cavity ho ka boloka bophara ba pulse ea li-nanoseconds tse 'maloa ka lebelo le phahameng la ho pheta-pheta (joalo ka megahertz e' maloa) le ho lumella matla a phahameng a ho otla, haholo-holo bakeng sa lits'ebetso tse hlokang litekanyetso tse phahameng tsa ho pheta-pheta le li-pulse tse khutšoanyane. Ha e kopantsoe le mekhoa e meng ea ho hlahisa pulse, matla a pulse a ka ntlafatsoa le ho feta.

Pulse control oflaserke ts'ebetso e rarahaneng le ea bohlokoa, e kenyelletsang taolo ea bophara ba pulse, taolo ea maqhubu a sekhahla le mekhoa e mengata ea ho feto-fetoha ha molumo. Ka khetho e nepahetseng le ts'ebeliso ea mekhoa ena, ts'ebetso ea laser e ka fetoloa ka nepo ho fihlela litlhoko tsa maemo a fapaneng a ts'ebeliso. Nakong e tlang, ka ho tsoela pele ho hlaha ha lisebelisoa tse ncha le mahlale a macha, thekenoloji ea taolo ea pulse ea lasers e tla tlisa katleho e eketsehileng, le ho khothaletsa nts'etsopele eatheknoloji ea laserka tataiso ea ho nepahala ho phahameng le ts'ebeliso e pharaletseng.
