Pulse Energy ya Er: Magalasi a Laser Transmitters

M'madera a laser kuyambira, kutchulidwa kwa chandamale, ndi LiDAR, Er: Ma transmitters a magalasi agalasi akhala akugwiritsidwa ntchito kwambiri ma lasers apakati pa infrared solid-state chifukwa cha chitetezo chawo cha maso komanso kapangidwe kake kakang'ono. Pakati pa magawo awo ogwirira ntchito, mphamvu ya pulse imagwira ntchito yofunika kwambiri pakuzindikira kuthekera, kufalikira kwamitundu yosiyanasiyana, komanso kuyankha kwamakina onse. Nkhaniyi ikupereka kusanthula kwakuya kwa mphamvu ya pulse ya Er:Glass laser transmitters.

1. Kodi Pulse Energy ndi Chiyani?

Mphamvu ya pulse imatanthawuza kuchuluka kwa mphamvu zomwe zimatulutsidwa ndi laser pamtundu uliwonse, womwe umayesedwa mu millijoules (mJ). Ndiwopangidwa ndi mphamvu yayikulu komanso nthawi yayitali: E = P_nsonga× t. Kumeneko: E ndi mphamvu ya pulse, P_nsonga ndiye mphamvu yayikulu,τ ndi pulse width.

Kwa Er: Magalasi agalasi omwe amagwira ntchito pa 1535 nm-kutalika kwa mafunde mu gulu la Class 1 loteteza maso-Kuthamanga kwamphamvu kwamphamvu kumatha kupezedwa ndikusunga chitetezo, kuwapangitsa kukhala oyenera kunyamula komanso panja.

2. Pulse Energy Range ya Er: Magalasi agalasi

Kutengera kapangidwe kake, njira ya mpope, ndi momwe amagwiritsidwira ntchito, malonda a Er:Magalasi otumizira magalasi amapereka mphamvu ya pulse imodzi kuyambira makumi a ma microjoules (μJ) mpaka makumi angapo a millijoules (mJ).

Nthawi zambiri, Er: Ma transmitters agalasi omwe amagwiritsidwa ntchito m'magawo ang'onoang'ono osiyanasiyana amakhala ndi mphamvu yapakati pa 0.1 mpaka 1 mJ. Kwa opanga zolinga zazitali, 5 mpaka 20 mJ nthawi zambiri imafunikira, pomwe zida zankhondo kapena zamafakitale zimatha kupitilira 30 mJ, nthawi zambiri zimagwiritsa ntchito zokulitsa zamagulu awiri kapena masitepe angapo kuti zikwaniritse zotulutsa zambiri.

Kuthamanga kwamphamvu kwamphamvu nthawi zambiri kumapangitsa kuti munthu azitha kuzindikira bwino, makamaka m'mikhalidwe yovuta monga ma siginecha ofooka obwerera kapena kusokonezedwa ndi chilengedwe pazitali zazitali.

3. Zomwe Zimakhudza Mphamvu ya Pulse

①Ntchito ya Pump Source

Er:Magalasi agalasi amapopedwa ndi ma laser diode (LDs) kapena nyali. Ma LDs amapereka mphamvu zambiri komanso kuphatikizika koma amafuna kuwongolera koyenera kwa kutentha ndi kuyendetsa.

②Kukhazikika kwa Doping ndi Kutalika kwa Ndodo

Zida zosiyanasiyana zochitira zinthu monga Er:YSGG kapena Er:Yb:Glass zimasiyana m'miyezo yake ya doping ndikuwonjezera utali, zomwe zimakhudza mwachindunji kusungirako mphamvu.

③Q-Switching Technology

Passive Q-switching (mwachitsanzo, ndi Cr:YAG makhiristo) imathandizira kapangidwe kake koma imapereka kuwongolera kocheperako. Kusinthasintha kwa Q (mwachitsanzo, ndi ma Pockels cell) kumapereka kukhazikika kwapamwamba komanso kuwongolera mphamvu.

④Thermal Management

Pamphamvu zamphamvu kwambiri, kutentha kwamphamvu kwa laser ndodo ndi kapangidwe ka chipangizo ndikofunikira kuti zitsimikizire kukhazikika komanso moyo wautali.

4. Kufananiza Mphamvu ya Pulse ndi Zochitika Zogwiritsira Ntchito

Kusankha Er yoyenera: Chotumizira laser chagalasi zimatengera kwambiri ntchito yomwe mukufuna. M'munsimu muli zina zomwe zimagwiritsidwa ntchito nthawi zambiri komanso zofananira ndi mphamvu zamagetsi:

①M'manja Laser Rangefinders

Mawonekedwe: compact, mphamvu yochepa, miyeso yayifupi yafupipafupi kwambiri

Mphamvu ya Pulse Energy: 0.5-1 mj

②Kuthamanga kwa UAV / Kupewa Zopinga

Mawonekedwe: kutalika kwapakatikati, kuyankha mwachangu, kopepuka

Mphamvu ya Pulse Energy: 1-5 mj

③Okonza Zolinga Zankhondo

Mawonekedwe: kulowa kwakukulu, kutsutsa mwamphamvu, kuwongolera kwanthawi yayitali

Mphamvu ya Pulse yovomerezeka: 10-30 mj

④LiDAR Systems

Mawonekedwe: kubwereza kwakukulu, kusanthula kapena kupanga mtambo

Mphamvu ya Pulse Energy: 0.1-10 mj

5. Zochitika Zam'tsogolo: Mphamvu Zapamwamba & Kupaka Pang'onopang'ono

Ndi kupita patsogolo kopitilira muyeso muukadaulo wa magalasi opangira magalasi, kapangidwe ka mapampu, ndi zida zotenthetsera, Er:Magalasi otumizira magalasi akusintha kupita kuphatikiziro lamphamvu kwambiri, kubwereza kwapamwamba, ndi miniaturization. Mwachitsanzo, makina ophatikizira kukulitsa masitepe ambiri ndi mapangidwe osinthika a Q tsopano atha kutulutsa 30 mJ pa kugunda kwinaku akusunga mawonekedwe ophatikizika.-abwino kwa kuyeza kwautali ndi ntchito zodalirika zodalirika kwambiri.

6. Mapeto

Mphamvu ya kugunda ndi chizindikiro chachikulu cha magwiridwe antchito pakuwunika ndikusankha Er:Magalasi otumizira magalasi kutengera zomwe mukufuna. Pamene matekinoloje a laser akupitilirabe kusinthika, ogwiritsa ntchito amatha kupeza mphamvu zochulukirapo komanso kusiyanasiyana pazida zing'onozing'ono, zogwiritsa ntchito mphamvu zambiri. Kwa machitidwe omwe amafunikira kugwira ntchito kwa nthawi yayitali, chitetezo cha maso, ndi kudalirika kwa magwiridwe antchito, kumvetsetsa ndikusankha mtundu wamagetsi oyenera ndikofunikira kuti muwonjezere mphamvu zamakina ndi mtengo wake.

Ngati inu'mukuyang'ananso Er: Ma transmitters agalasi agalasi, omasuka kutilumikizana nafe. Timapereka mitundu yosiyanasiyana yokhala ndi mphamvu yamphamvu kuyambira 0.1 mJ mpaka 30 mJ, yoyenera kugwiritsa ntchito mitundu yosiyanasiyana ya laser kuyambira, LiDAR, ndi kutchulidwa chandamale.
