Pulse Energy yeEr:Glass Laser Transmitters

Muminda yekutarisa ma laser, kusarudzwa kwezvinangwa, uye LiDAR, ma Er:Glass laser transmitters ave kushandiswa zvakanyanya ma mid-infrared solid-state lasers nekuda kwekuchengetedzeka kwavo kwakanaka kwemaziso uye dhizaini yavo diki. Pakati pema parameter avo ekushanda, simba re pulse rinoita basa rakakosha mukuona kugona kuona, kufukidza nzvimbo, uye kupindura kwese kwesystem. Chinyorwa chino chinopa ongororo yakadzama yesimba re pulse rema Er:Glass laser transmitters.

1. Chii Chinonzi Pulse Energy?

Simba repulse rinoreva huwandu hwesimba rinoburitswa nelaser mupulse yega yega, inowanzo kuyerwa mumamilijoules (mJ). Ihwo chibereko chesimba repamusoro uye nguva yepulse: E = P_nhongonya×τKupi: E ndiyo simba rekurova kwemoyo, P_nhongonya ndiyo simba guru,τ ndiyo upamhi hwekurova kwemoyo.

Kune maEr:Girazi lasers akajairika anoshanda pa1535 nm—kureba kwewavelength muchikamu chekutanga chekudzivirira maziso—Simba rekurova kwemoyo rakawanda rinogona kuwanikwa uku uchichengetedza kuchengetedzeka, zvichiita kuti zvive zvakakodzera kushandiswa pakutakura uye panze.

2. Pulse Energy Range yeEr:Glass Lasers

Zvichienderana nedhizaini, nzira yekupomba, uye mashandisirwo azvo, maEr:Glass laser transmitters ekutengesa anopa simba rekurova kwemoyo rimwe chete kubva pamakumi ema microjoules (μJ) kune makumi akati wandei ema millijoules (mJ).

Kazhinji, maEr:Glass laser transmitters anoshandiswa muma miniature ranging modules ane simba re pulse range re 0.1 kusvika 1 mJ. Kune vanogadzira target range refu, 5 kusvika 20 mJ inowanzo diwa, nepo masisitimu emauto kana eindasitiri anogona kudarika 30 mJ, achiwanzoshandisa zvivakwa zve dual-rod kana multi-stage amplification kuti awane goho rakawanda.

Simba guru rekurova kwemoyo rinowanzoita kuti munhu aone zviri nani, kunyanya mumamiriro ezvinhu akaoma akadai sekudzoka kusina simba kana kukanganiswa kwezvakatipoteredza munzvimbo refu.

3. Zvinhu Zvinokanganisa Simba rePulse

①Kushanda Kwepombi

Er:Magirazi elaser anowanzo pombiwa nelaser diodes (LDs) kana flashlamps. MaLD anopa kushanda kwakanyanya uye kupfupika asi anoda kudzora kwakaringana kwethermal uye driving circuit.

②Kuisa Doping Concentration uye Kureba kweRod

Zvinhu zvakasiyana-siyana zvinoshandisa simba remagetsi zvakaita seEr:YSGG kana Er:Yb:Girazi zvinosiyana padanho rekushandisa zvinodhaka uye kureba kwaro, zvichikanganisa zvakananga kugona kwekuchengetedza simba.

③Tekinoroji yeQ-Switching

Kuchinja-chinja kweQ (semuenzaniso, nemakristaro eCr:YAG) kunoita kuti chimiro chive nyore asi kunopa kurongeka kushoma kwekudzora. Kuchinja-chinja kweQ (semuenzaniso, nemaPockels cells) kunopa kugadzikana kwakanyanya uye kutonga simba.

④Kutarisira Kupisa

Kana simba rekupisa rakawanda, kupisa kunobva pamuti welaser uye chimiro chemudziyo kwakakosha kuti pave nechokwadi chekuti zvinobuda zvinogadzikana uye kuti zvinogara kwenguva refu.

4. Kuenzanisa Simba rePulse neZviitiko zveKushandisa

Kusarudza Er:Glass laser transmitter chaiyo kunoenderana zvakanyanya nekushandiswa kwayo. Heano mamwe mashandisirwo akajairika uye mazano anoenderana ne pulse energy:

①Zvishandiso zveLaser zvinobatwa nemaoko

Zvimiro: diki, simba rakaderera, kuyerwa kwenzvimbo pfupi-pfupi-kwakawanda

Simba rePulse Rinokurudzirwa: 0.5–1 mJ

②Kudzivirira Zvipingamupinyi zveUAV / Kudzivirira Zvipingamupinyi

Zvimiro: pakati nepakati kusvika kure, mhinduro inokurumidza, yakareruka

Simba rePulse Rinokurudzirwa: 1–5 mJ

③Vagadziri veMauto

Zvinhu: kupinda kwepamusoro-soro, kudzivirira kupindira kwakasimba, nhungamiro yekurova kure

Simba rePulse Rinokurudzirwa: 10–30 mJ

④Masisitimu eLiDAR

Zvimiro: mwero wepamusoro wekudzokorora, kuongorora kana kugadzira gore renzvimbo

Simba rePulse Rinokurudzirwa: 0.1–10 mJ

5. Mafambiro Emangwana: Simba Rakawanda & Kurongedza Kwakapfupika

Nekufambira mberi kuri kuenderera mberi mu tekinoroji yekushandisa magirazi, mapombi, uye zvinhu zvinopisa, maEr:Glass laser transmitters ari kushanduka achienda kumubatanidzwa wesimba rakawanda, mwero wekudzokorora wakakwira, uye miniaturization. Semuenzaniso, masisitimu anobatanidza multi-stage amplification nemagadzirirwo anoshandiswa neQ-switched anogona ikozvino kupa anopfuura 30 mJ pakurova kwemoyo uku achichengetedza compact form factor.—Yakanakira kuyera kure uye kushandiswa kwekudzivirira kwakasimba.

6. Mhedziso

Simba remhepo (pulse energy) chiratidzo chakakosha chekushanda kwekuongorora nekusarudza maEr:Glass laser transmitters zvichienderana nezvinodiwa zvekushandisa. Sezvo matekinoroji emagetsi emhepo achiramba achichinja, vashandisi vanogona kuwana simba rakawanda uye nzvimbo yakakura mumidziyo midiki, inoshanda nesimba zvakanyanya. Kune masisitimu anoda kushanda kwenguva refu, kuchengetedzeka kwemaziso, uye kuvimbika kwekushanda, kunzwisisa nekusarudza huwandu hwakakodzera hwesimba remhepo kwakakosha pakuwedzera kushanda zvakanaka kwesisitimu uye kukosha kwayo.

Kana iwe'Tiri kutsvaga maEr:Glass laser transmitters anoshanda zvakanaka, inzwa wakasununguka kutibata. Tinopa mhando dzakasiyana dzemamodheru ane pulse energy specifications kubva pa0.1 mJ kusvika pamusoro pe30 mJ, akakodzera kushandiswa kwakasiyana-siyana mu laser ranging, LiDAR, uye target designation.
