Pulse Energy ea Er: Li-transmitters tsa Laser tsa Khalase

Mafapheng a laser rangeng, target designation, le LiDAR, Er:Glas laser transmitters li se li sebelisoa haholo li-laser tsa boemo bo bohareng ba infrared ka lebaka la polokeho ea mahlo ea tsona e ntle le moralo o kopaneng. Har'a liparamente tsa bona tsa ts'ebetso, matla a pulse a bapala karolo ea bohlokoa ho khethollang bokhoni ba ho lemoha, ho fana ka tšireletso ea mefuta-futa, le karabelo ea sistimi ka kakaretso. Sengoliloeng sena se fana ka tlhahlobo e tebileng ea matla a pulse a Er:Glass laser transmitters.

1. Pulse Energy ke Eng?

Pulse energy e bolela boholo ba matla a hlahisoang ke laser ho phallo e 'ngoe le e' ngoe, eo hangata e lekantsoeng ka millijoules (mJ). Ke sehlahisoa sa matla a holimo le nako ea ho otla ha pelo: E = P_tlhoro× t. Moo: E ke matla a pulse, P_tlhoro ke matla a phahameng,τ ke bophara ba pulse.

Bakeng sa lisebelisoa tse tloaelehileng tsa Er:Laser tsa khalase tse sebetsang ho 1535 nm-bolelele ba maqhubu sehlopheng sa 1 se sireletsang mahlo-matla a phahameng a pulse a ka finyelloa ha a ntse a boloka tšireletseho, a etsa hore a tšoanelehe ka ho khetheha bakeng sa lisebelisoa tse nkehang habonolo le tsa ka ntle.

2. Pulse Energy Range ea Er: Glass Lasers

Ho ipapisitsoe le moralo, mokhoa oa pompo, le ts'ebeliso e reriloeng, khoebo ea Er:Glass laser transmitters e fana ka matla a matla a tsoang ho mashome a microjoules.μJ) ho isa ho mashome a 'maloa a millijoules (mJ).

Ka kakaretso, Er: Li-transmitters tsa laser tse sebelisoang mefuteng e menyenyane ea ho fapana li na le matla a ho otla a 0.1 ho isa ho 1 mJ. Bakeng sa baqapi ba sepheo sa nako e telele, 5 ho 20 mJ hangata e hlokahala, ha litsamaiso tsa sesole kapa tsa indasteri li ka feta 30 mJ, hangata li sebelisa mekhoa ea ho hōlisa lithupa tse peli kapa tse ngata ho finyella tlhahiso e phahameng.

Matla a phahameng a ho otla ha pelo ka kakaretso a fella ka ts'ebetso e ntlafetseng ea ho lemoha, haholo-holo tlas'a maemo a thata joalo ka matšoao a fokolang a ho khutla kapa tšitiso ea tikoloho libakeng tse telele.

3. Lintlha tse Amang Pulse Energy

①Ts'ebetso ea Mohloli oa Pompo

Er: Li-laser tsa khalase hangata li pompuoa ka li-laser diode (LDs) kapa li-flashlights. Li-LD li fana ka ts'ebetso e phahameng le compactness empa li hloka taolo e nepahetseng ea mocheso le ho khanna.

②Mahlohonolo a Doping le Bolelele ba Molamu

Lisebelisoa tse fapaneng tsa moamoheli joalo ka Er:YSGG kapa Er:Yb:Glass lia fapana ho ea ka maemo a tsona a doping le ho eketsa bolelele, e amang matla a polokelo ea matla ka kotloloho.

③Q-Switching Technology

Passive Q-switching (mohlala, ka Cr:YAG crystals) e nolofatsa sebopeho empa e fana ka taolo e nepahetseng e fokolang. Active Q-switching (mohlala, ka lisele tsa Pockels) e fana ka botsitso bo phahameng le taolo ea matla.

④Tsamaiso ea Mocheso

Ka matla a phahameng a pulse, ho senya mocheso o sebetsang hantle ho tloha molamu oa laser le sebopeho sa lisebelisoa ke habohlokoa ho netefatsa botsitso ba tlhahiso le bophelo bo bolelele.

4. Ho Bapisa Matla a Pulse le Maemo a Kopo

Ho khetha Er e nepahetseng: Transmitter ea laser ea khalase e itšetlehile haholo ka ts'ebeliso e reriloeng. Ka tlase ke maemo a mang a ts'ebeliso e tloaelehileng le likhothaletso tse tsamaellanang tsa matla a pulse:

①Laser Rangefinders e tšoaroang ka letsoho

Likarolo: compact, matla a tlase, litekanyo tse khutšoane tsa maqhubu a holimo

Matla a Pulse a khothalelitsoeng: 0.5-1 mJ

②UAV Range / Thibelo ea Litšitiso

Likarolo: bohareng ba nako e telele, karabo e potlakileng, e bobebe

Matla a Pulse a khothalelitsoeng: 1-5 mJ

③Baqapi ba Maikemisetso a Sesole

Likarolo: ho kenella ho phahameng, ho thibela ho kena-kenana ho matla, tataiso ea nako e telele ea seteraeke

Matla a Pulse a khothalelitsoeng: 10-30 mJ

④Sistimi ea LiDAR

Likarolo: sekhahla se phahameng sa ho pheta-pheta, ho hlahloba kapa ho hlahisa maru

Matla a Pulse a khothalelitsoeng: 0.1-10 mJ

5. Mekhoa ea Bokamoso: Matla a Phahameng & Packaging Compact

Ka tsoelopele e tsoelang pele ho theknoloji ea doping ea khalase, meaho ea pompo, le lisebelisoa tsa mocheso, Er: Li-transmitters tsa laser tsa Glass li ntse li tsoela pele ho kopana le matla a phahameng, sekhahla se phahameng sa ho pheta-pheta, le miniaturization. Mohlala, lits'ebetso tse kopanyang matlafatso ea mekhahlelo e mengata ka meralo e sebetsang ea Q-switched joale e ka fana ka ho feta 30 mJ ka lebelo ha e ntse e boloka sebopeho se kopaneng.-e loketseng bakeng sa tekanyo ea nako e telele le lits'ebetso tsa ts'ireletso tse tšepahalang haholo.

6. Qetello

Pulse energy ke sesupo sa bohlokoa sa ts'ebetso bakeng sa ho lekola le ho khetha Er:Glass laser transmitters ho ipapisitsoe le litlhoko tsa ts'ebeliso. Ha mahlale a laser a ntse a tsoela pele ho fetoha, basebelisi ba ka fumana tlhahiso e phahameng ea matla le mefuta e mengata ea lisebelisoa tse nyane, tse sebetsang hantle haholoanyane. Bakeng sa lits'ebetso tse hlokang ts'ebetso ea nako e telele, polokeho ea mahlo, le ts'epahalo ea ts'ebetso, ho utloisisa le ho khetha mefuta e nepahetseng ea matla a pulse ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso le boleng ba sistimi.

Haeba u're batlana le Er:Li-transmitters tsa laser tse sebetsang hantle haholo, ikutloe u lokolohile ho ikopanya le rona. Re fana ka mefuta e fapaneng ea mefuta e nang le litlhaloso tsa matla a pulse ho tloha ho 0.1 mJ ho ea ho 30 mJ, e loketseng mefuta e mengata ea lisebelisoa tsa laser ho tloha, LiDAR, le ho khethoa ha sepheo.
