Chii chinonzi CW DPSS laser? Tsanangudzo Kuputsa-pasi

Continuous Wave (CW):Izvi zvinoreva maitiro ekushanda kwelaser. Mune CW modhi, iyo laser inoburitsa yakatsiga, inogara mwenje wechiedza, kupesana nemapuruzi lasers anoburitsa mwenje mukuputika. CW lasers inoshandiswa kana inoenderera, yakatsiga mwenje kubuda ichidikanwa, sekucheka, welding, kana kunyora maapplication.

Diode Pumping:Mune diode-pumped lasers, iro simba rinoshandiswa kufadza iyo laser medium rinopihwa semiconductor laser diodes. Aya diode anoburitsa mwenje unotorwa nelaser medium, inonakidza maatomu ari mukati mayo uye ichivabvumira kuburitsa mwenje wakabatana. Diode kupomba inoshanda zvakanyanya uye inovimbika kana ichienzaniswa neyekare nzira dzekupomba, senge marambi, uye inobvumira mamwe compact uye anogara akasimba laser dhizaini.

Solid-State Laser:Izwi rekuti "solid-state" rinoreva rudzi rwekuwana svikiro rinoshandiswa mulaser. Kusiyana negasi kana mvura lasers, solid-state lasers inoshandisa yakasimba zvinhu sepakati. Iyi svikiro inowanzoita sekristaro, senge Nd: YAG (Neodymium-doped Yttrium Aluminium Garnet) kana Ruby, yakashongedzwa nezvinhu zvisingawanzo pasi zvinogonesa kugadzirwa kwelaser light. Iyo doped crystal ndiyo inokwidziridza mwenje kuti ibudise laser beam.

Wavelengths uye Zvishandiso:DPSS lasers inogona kuburitsa kune akasiyana wavelengths, zvichienderana nerudzi rwedoping zvinhu zvinoshandiswa mukristaro uye dhizaini yelaser. Semuyenzaniso, yakajairwa DPSS laser kumisikidzwa inoshandisa Nd: YAG senzira yekuwana yekugadzira laser pa1064 nm mune infrared spectrum. Iri rudzi rwelaser rinoshandiswa zvakanyanya mumaindasitiri ekushandisa kucheka, welding, uye kumaka zvinhu zvakasiyana.

Zvakanakira:DPSS lasers inozivikanwa nehupamhi hwayo hwemhando, kugona, uye kuvimbika. Iwo anonyanya kushanda nesimba kupfuura echinyakare akasimba-nyika lasers anopombwa nemwenje uye anopa hupenyu hurefu hwekushanda nekuda kwekusimba kwema diode lasers. Ivo zvakare vanokwanisa kugadzira yakagadzikana uye chaiyo laser matanda, ayo akakosha kune yakadzama uye yakakwirira-chaiyo maapplication.

Kushandiswa kwakakosha kweCW Diode Pumped Solid State Laser:

1.Laser Diamond Kucheka:

Iyo G2-A laser inoshandisa yakajairwa gadziriso yekupeta kaviri: infrared yekuisa danda pa1064 nm inoshandurwa kuita girinhi 532-nm wave apo ichipfuura nepakati pekristaro isina mutsetse. Iyi nzira, inozivikanwa sefrequency doubling kana yechipiri harmonic generation (SHG), inzira inogamuchirwa nevakawanda yekugadzira mwenje papfupi wavelengths.

Nekupeta kaviri kuwanda kwekubuda kwemwenje kubva kune neodymium- kana ytterbium-based 1064-nm laser, yedu G2-A laser inogona kuburitsa girinhi mwenje pa532 nm. Iyi tekinoroji yakakosha pakugadzira magreen lasers, ayo anowanzo shandiswa mumashandisirwo kubva kune laser anongedza kusvika kune akaomesesa esainzi uye maindasitiri zviridzwa, uye zvakare kuve akakurumbira muLaser Diamond Cutting Area.

2. Material Processing:

 Aya ma lasers anoshandiswa zvakanyanya mukugadzira zvinhu zvekushandisa sekucheka, welding, uye kudhirowa kwesimbi nezvimwe zvinhu. Kunyatsoita kwavo kwepamusoro kunoita kuti ive yakanakira dhizaini uye kucheka, kunyanya mumaindasitiri emotokari, aerospace, uye zvemagetsi.

3. Zvikumbiro zvekurapa:

Mundima yekurapa, CW DPSS lasers inoshandiswa pakuvhiya inoda kunyatsojeka, sekuvhiyiwa kwemaziso (seLASIK yekugadzirisa kuona) uye nzira dzakasiyana dzemazino. Kugona kwavo kunyatso kunanga matishu kunoita kuti ive yakakosha mukuvhiya kushoma.

4. Tsvakurudzo yeSainzi:

Aya ma lasers anoshandiswa mune akati wandei mashandisirwo esainzi, anosanganisira spectroscopy, particle image velocimetry (inoshandiswa mune fluid dynamics), uye laser scanning microscopy. Kubuda kwavo kwakagadzikana kwakakosha pakuyera kuyerwa uye kucherechedzwa mukutsvaga.

5. Nharembozha:

Mundima yenharembozha, DPSS lasers inoshandiswa mufiber optic masisitimu ekutaurirana nekuda kwekugona kwavo kugadzira danda rakagadzikana uye rinoenderana, izvo zvinodiwa pakufambisa data pamusoro pemadaro marefu kuburikidza neoptical fibers.

6. Laser Engraving uye Kumaka:

Kunyatsoita uye kugona kweCW DPSS lasers kunoita kuti ive yakakodzera kunyora uye kumaka zvakasiyana-siyana zvezvinhu, zvinosanganisira simbi, mapurasitiki, uye ceramics. Iwo anowanzo shandiswa kuita barcoding, serial manhamba, uye personalizing zvinhu.

7. Dziviriro uye Chengetedzo:

Aya ma lasers anowana maapplication mukudzivirira kune chinangwa chekudanwa, kutsvaga kwemhando, uye infrared mwenje. Kuvimbika kwavo uye kurongeka kwakakosha munzvimbo idzi dzepamusoro-soro.

8. Semiconductor Manufacturing:

Muindasitiri yesemiconductor, CW DPSS lasers inoshandiswa kumabasa senge lithography, annealing, uye kuongororwa kwesemiconductor wafers. Iyo chaiyo laser's kwakakosha pakugadzira iyo microscale zvimiro pane semiconductor machipisi.

9. Varaidzo uye Kuratidzwa:

Iwo anoshandiswawo muindasitiri yevaraidzo yezviratidziro zvemwenje uye fungidziro, uko kugona kwavo kugadzira mwenje wakajeka uye wakanyanya kunobatsira.

10. Biotechnology:

Mubiotechnology, ma lasers aya anoshandiswa mumashandisirwo akaita seDNA kutevedzana uye kurongedza masero, uko kurongeka kwavo uye kudzorwa simba rekubuda kwakakosha.

11. Metrology:

Nekuyera kuyerwa uye kurongeka muinjiniya nekuvaka, CW DPSS lasers inopa huchokwadi hunodiwa pamabasa akadai sekuyera, kurongeka, uye kurongeka.
