Muminda yelaser inotangira, kudoma zita, uye LiDAR, Er: Girazi laser transmitters ave kushandiswa zvakanyanya yepakati-infrared solid-state lasers nekuda kwekuchengetedza kwemaziso kwakanyanya uye dhizaini. Pakati pemaitiro avo ekuita, pulse simba rinoita basa rakakosha mukuona kugona kwekuona, kuvharika kwemhando, uye kuterera kwese system. Ichi chinyorwa chinopa kuongororwa kwakadzama kwesimba rekupuruzira reEr:Glass laser transmitters.
1. Chii chinonzi Pulse Energy?
Pulse energy inoreva huwandu hwesimba rinoburitswa nelaser mune yega yega pulse, inowanzoyerwa mumamilijoules (mJ). Icho chigadzirwa chepamusoro simba uye pulse nguva: E = Ppeak×τ. Ikoko: E ndiyo pulse simba, Ppeak ndiro simba repamusoro,τ ndiko hupamhi hwepulse.
Kune yakajairika Er: Girazi lasers inoshanda pa1535 nm-wavelength muKirasi 1 bhendi rinochengetedza maziso-high pulse energy inogona kuwanikwa uchichengetedza kuchengeteka, zvichiita kuti zvive zvakanyanya kukodzera kune inotakurika uye yekunze application.
2. Pulse Energy Range yeEr:Glass Lasers
Zvichienderana nedhizaini, nzira yepombi, uye chinangwa chekushandiswa, kutengeserana Er:Glass laser transmitters inopa imwechete-pulse simba kubva kumakumi e microjoules (μJ) kusvika makumi akati wandei emamirijoules (mJ).
Kazhinji, Er:Glass laser transmitters anoshandiswa mune diki kubva mamodules ane pulse simba renji ye0.1 kusvika 1 mJ. Kune vagadziri vezvinangwa zvenguva refu, 5 kusvika 20 mJ inowanzodiwa, nepo mauto kana maindasitiri-giredhi masisitimu anogona kudarika 30 mJ, kazhinji achishandisa dual-rod kana akawanda-stage amplification maumbirwo kuti awane yakakwirira goho.
Simba repamusoro-soro rinowanzoita kuti zvionekwe zviri nani, kunyanya pasi pemamiriro ezvinhu akaoma akadai sezviratidzo zvisina simba zvekudzoka kana kukanganisa kwezvakatipoteredza munzvimbo dzakareba.
3. Zvinhu Zvinokanganisa Pulse Energy
①Pump Source Performance
Er:Glass lasers anowanzo kupomba nelaser diodes (LDs) kana mwenje. MaLDs anopa hunyanzvi hwepamusoro uye compactness asi inoda chaiyo kupisa uye kutyaira wedunhu kutonga.
②Doping Concentration uye Kureba kwetsvimbo
Zvishandiso zvakasiyana siyana seEr:YSGG kana Er:Yb:Glasi rinosiyana mumatanho edoping uye rinowedzera kureba, zvichikanganisa simba rekuchengetedza simba.
③Q-Switching Technology
Passive Q-switching (semuenzaniso, neCr: YAG makristasi) inorerutsa chimiro asi inopa kushomeka kwekutonga kurongeka. Active Q-switching (semuenzaniso, nePockels masero) inopa kugadzikana kwepamusoro uye kutonga kwesimba.
④Thermal Management
Pamasimba makuru ekupuruzira, kupisa kunoshanda kubva kune laser tsvimbo uye mudziyo chimiro kwakakosha kuti uve nechokwadi chekubuda kugadzikana uye hupenyu hurefu.
4. Kufananidza Pulse Energy kune Mamiriro Ekushandisa
Kusarudza iyo chaiyo Er:Glass laser transmitter inoenderana zvakanyanya neyakagadzirirwa application. Pazasi pane akajairika makesi ekushandisa uye anowirirana pulse simba kurudziro:
①Handheld Laser Rangefinders
Zvimiro: compact, yakaderera simba, yakakwirira-frequency pfupi-renji zviyero
Yakakurudzirwa Pulse Energy: 0.5-1 mJ
②UAV Kutarisa / Kudzivisa Kudzivisa
Zvimiro: yepakati-kusvika-yakareba, kukurumidza kupindura, kureruka
Inokurudzirwa Pulse Energy: 1-5 mJ
③Mauto Chinangwa Vagadziri
Zvimiro: kupindira kwepamusoro, kupikisa kwakasimba-kupindira, kutungamira kwekurova kwenguva refu
Inokurudzirwa Pulse Energy: 10-30 mJ
④LiDAR Systems
Zvimiro: yakakwira kudzokorora mwero, scanning kana point cloud generation
Yakakurudzirwa Pulse Energy: 0.1-10 mJ
5. Future Trends: High Energy & Compact Packaging
Nekufambira mberi kuri kuitika mugirazi doping tekinoroji, pombi zvimiro, uye zvinopisa zvinhu, Er: Girazi laser transmitters ari kushanduka akananga kusanganiswa kwesimba repamusoro, mwero wekudzokorora wakakwira, uye miniaturization. Semuyenzaniso, masisitimu anobatanidza akawanda-nhanho amplification ane anoshingairira Q-switched madhizaini anogona ikozvino kuunza pamusoro pe30 mJ papuruse uchichengetedza compact fomu chinhu.-yakanakira kuyera-refu-refu uye yakakwirira-yakavimbika kudzivirira zvikumbiro.
6. Mhedziso
Pulse simba ndiyo yakakosha kuita chiratidzo chekuongorora nekusarudza Er:Glass laser transmitters zvichienderana nezvinodiwa zvekushandisa. Sezvo tekinoroji yelaser ichiramba ichishanduka, vashandisi vanogona kuwana yakakwira simba rekubuda uye yakakura huwandu mune zvidiki, zvine simba-rinoshanda zvishandiso. Kune masisitimu anoda kuita kwenguva refu, kuchengetedzwa kweziso, uye kuvimbika kwekushanda, kunzwisisa uye kusarudza iyo chaiyo pulse simba renji kwakakosha mukuwedzera mashandiro ehurongwa uye kukosha.
Kana iwe'uchitsvaga epamusoro-inoshanda Er: Girazi laser transmitters, inzwa wakasununguka kutibata. Isu tinopa akasiyana-siyana emhando ane pulse simba zvirevo kubva pa 0.1 mJ kusvika pamusoro pe30 mJ, akakodzera kuwanda kwekushandisa mu laser inotangira, LiDAR, uye chinangwa chezita.
