Emkhakheni wobubanzi be-laser, ukuqokwa okuqondisiwe, kanye ne-LiDAR, Er:Izidluliseli ze-laser zengilazi sezisetshenziswa kakhulu amalaser wesifunda esiqinile esimaphakathi ne-infrared ngenxa yokuphepha kwawo okuhle kakhulu kwamehlo kanye nomklamo ohlangene. Phakathi kwamapharamitha wabo wokusebenza, amandla okushaya kwenhliziyo adlala indima ebalulekile ekunqumeni amandla okuthola, ukumbozwa kobubanzi, kanye nokusabela kwesistimu kukonke. Lesi sihloko sinikeza ukuhlaziya okujulile kwamandla we-pulse Er:Glass laser transmitters.
1. Iyini I-Pulse Energy?
I-Pulse energy isho inani lamandla akhishwa i-laser ku-pulse ngayinye, ngokuvamile elinganiswa ngama-millijoules (mJ). Kungumkhiqizo wamandla aphezulu kanye nobude be-pulse: E = Pisiqongo×τ. Kuphi: E yi-pulse energy, Pisiqongo amandla aphezulu,τ ububanzi be-pulse.
Kuma-laser e-Er:Glass asebenza ku-1535 nm-ubude begagasi ebhendini ephephile iso Yekilasi 1-amandla aphezulu e-pulse angafinyelelwa ngenkathi kugcinwa ukuphepha, okubenza bafaneleke ikakhulukazi izinhlelo zokusebenza eziphathwayo nezingaphandle.
2. I-Pulse Energy Range ye-Er:Ama-Glass Lasers
Ngokuya ngedizayini, indlela yokupompa, nokusetshenziswa okuhlosiwe, i-Er:Izidluliseli ze-laser ze-Glass zinikeza amandla okubhoboza okukodwa asukela kumashumi ama-microjoules (μJ) kuya kumashumi amaningana amamilijoule (mJ).
Ngokuvamile, i-Er:Izidlulisi ze-laser zengilazi ezisetshenziswa kumamojula amancane asukela zinebanga lokushaya kwamandla ka-0.1 kuya ku-1 mJ. Kubaklami abaqondiwe bebanga elide, u-5 kuya ku-20 mJ ngokuvamile uyadingeka, kuyilapho amasistimu ezempi noma ebanga lezimboni angase eqe u-30 mJ, ngokuvamile asebenzisa izakhiwo zokukhulisa ezi-dual-rod noma zezigaba eziningi ukuze kutholwe umphumela ophezulu.
Amandla okushaya kwenhliziyo aphezulu ngokuvamile aphumela ekusebenzeni okungcono kokutholwa, ikakhulukazi ngaphansi kwezimo eziyinselele ezifana namasiginali okubuyisela ebuthaka noma ukuphazamiseka kwemvelo ebangeni elide.
3. Izici Ezithinta I-Pulse Energy
①Ukusebenza Komthombo Wephampu
Er:Ama-laser engilazi ngokuvamile ampontshwa ngama-laser diode (LDs) noma ama-flashlamps. Ama-LD anikeza ukusebenza kahle okuphezulu nokubumbana kodwa adinga ukulawulwa kwesekethe okushisayo nokushayela.
②I-Doping Concentration kanye Nobude Benduku
Izinto zokusingathwa ezihlukene ezifana ne-Er:YSGG noma i-Er:Yb:Glass ziyahlukahluka ngamaleveli azo e-doping futhi azuza ubude, okuthinta ngqo umthamo wokugcina amandla.
③I-Q-Switching Technology
I-Passive Q-switching (isb, ngamakristalu e-Cr:YAG) yenza ukwakheka kube lula kodwa kunikeza ukunemba kokulawula okulinganiselwe. Ukushintsha i-Q okusebenzayo (isb, ngamaseli e-Pockels) kunikeza ukuzinza okuphezulu nokulawula amandla.
④Ukuphatha Okushisayo
Emandleni aphezulu okushaya kwenhliziyo, ukuchithwa kokushisa okusebenzayo okuvela ku-laser rod kanye nesakhiwo sedivayisi kubalulekile ukuze kuqinisekiswe ukuqina okukhiphayo nokuphila isikhathi eside.
4. Ukufanisa I-Pulse Energy nezimo zohlelo lokusebenza
Ukukhetha i-Er elungile:Isidlulisi se-laser yengilazi sincike kakhulu kuhlelo oluhlosiwe. Ngezansi ezinye izimo zokusetshenziswa ezivamile kanye nezincomo ezihambisanayo zamandla e-pulse:
①Ephathwayo Laser Rangefinders
Izici: amandla ahlangene, aphansi, izilinganiso zebanga elifushane lemvamisa ephezulu
Amandla E-Pulse Anconyiwe: 0.5-1 mj
②Ububanzi be-UAV / Ukugwema Izithiyo
Izici: ibanga eliphakathi nobude, impendulo esheshayo, engasindi
Amandla E-Pulse Anconyiwe: 1-5 mj
③Abaklami Bethagethi Yezempi
Izici: ukungena okuphezulu, ukulwa nokuphazamiseka okuqinile, isiqondiso sesiteleka sebanga elide
Amandla E-Pulse Anconyiwe: 10-30 mj
④I-LiDAR Systems
Izici: izinga lokuphindaphinda eliphezulu, ukuskena noma iphuzu lesizukulwane samafu
Amandla E-Pulse Anconyiwe: 0.1-10 mj
5. Amathrendi Azayo: Amandla Aphezulu & Ukupakisha Okuhlangene
Ngokuthuthuka okuqhubekayo kubuchwepheshe be-doping yengilazi, izakhiwo zephampu, nezinto ezishisayo, i-Er:Izidlulisi ze-laser zengilazi ziguqukela ekuhlanganisweni kwamandla aphezulu, izinga lokuphindaphinda eliphezulu, kanye nokwenza kancane. Isibonelo, amasistimu ahlanganisa ukukhulisa izigaba eziningi ngemiklamo eshintshwayo ye-Q manje angakwazi ukuletha ngaphezu kuka-30 mJ ishayela ngalinye kuyilapho egcina ifomu elihlangene.-ilungele ukulinganisa ibanga elide kanye nezicelo zokuvikela ezinokwethenjelwa okuphezulu.
6. Isiphetho
I-Pulse energy iyinkomba yokusebenza eyinhloko yokuhlola nokukhetha i-Er:Glass laser transmitters ngokusekelwe kuzidingo zohlelo lokusebenza. Njengoba ubuchwepheshe be-laser buqhubeka nokuvela, abasebenzisi bangafinyelela ukukhishwa kwamandla okuphezulu kanye nobubanzi obukhulu kumadivaysi amancane, asebenza kahle kakhulu. Kumasistimu afuna ukusebenza kwebanga elide, ukuphepha kwamehlo, nokwethembeka ekusebenzeni, ukuqonda nokukhetha ububanzi obufanele bokushaya kwe-pulse kubalulekile ukuze kukhuliswe ukusebenza kahle kwesistimu kanye nenani.
Uma u'ufuna kabusha i-Er:Izidluliseli ze-laser zengilazi ezisebenza kahle kakhulu, zizwe ukhululekile ukusithinta. Sinikeza amamodeli ahlukahlukene anezincazelo zamandla okushaya kwenhliziyo asukela ku-0.1 mJ kuye kwangaphezu kuka-30 mJ, afanelekela uhla olubanzi lwezinhlelo zokusebenza ku-laser esukela, i-LiDAR, kanye negama eliqondiwe.
