Iyini i-laser ye-CW DPSS? Ukuhlukaniswa kwencazelo

I-Continuous Wave (CW):Lokhu kubhekisela kumodi yokusebenza ye-laser. Kumodi ye-CW, i-laser ikhipha umsebe wokukhanya ozinzile, ongaguquki, ngokuphambene namalaser ashayayo akhipha ukukhanya ngokuqhuma. Amalaser e-CW asetshenziswa uma kudingeka ukukhanya okuqhubekayo, okungaguquki, njengokusika, ukushisela, noma izinhlelo zokusebenza eziqoshiwe.

I-Diode Pumping:Kuma-lasers ampompa i-diode, amandla asetshenziselwa ukujabulisa i-laser medium ahlinzekwa ngama-semiconductor laser diode. Lawa ma-diode akhipha ukukhanya okumuncwa i-laser medium, ajabulise ama-athomu angaphakathi kwawo futhi awavumele ukuthi akhiphe ukukhanya okuhambisanayo. Ukupompa i-Diode kusebenza kahle kakhulu futhi kuthembekile uma kuqhathaniswa nezindlela zakudala zokupompa, njengama-flashlamps, futhi kuvumela imiklamo ye-laser ehlangene futhi ehlala isikhathi eside.

I-Solid-State Laser:Igama elithi "solid-state" libhekisela ohlotsheni lwendawo yokuzuza esetshenziswa kulaser. Ngokungafani nama-laser egesi noma awuketshezi, ama-laser esifunda esiqinile asebenzisa into eqinile njengendawo ephakathi. Le medium ngokuvamile iyikristalu, njenge-Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) noma i-Ruby, ehlanganiswe nezinto ezingavamile zomhlaba ezivumela ukukhiqizwa kokukhanya kwe-laser. Ikristalu ene-doped yiyona ekhulisa ukukhanya ukuze kukhiqizwe i-laser beam.

Ama-wavelengths kanye nezicelo:Amalaser e-DPSS angaphuma ngamaza ahlukahlukene, kuye ngohlobo lwezinto zokudotshwa ezisetshenziswa kukristalu kanye nomklamo we-laser. Isibonelo, ukucushwa kwelaser ye-DPSS okuvamile kusebenzisa i-Nd:YAG njengendlela yokuthola ukukhiqiza i-laser ku-1064 nm ku-spectrum ye-infrared. Lolu hlobo lwe-laser lusetshenziswa kakhulu ezimbonini zokusika, ukushisela, nokumaka izinto ezahlukahlukene.

Izinzuzo:Ama-laser e-DPSS aziwa ngekhwalithi yawo ephezulu yomugqa, ukusebenza kahle, nokuthembeka. Awonga kakhulu amandla kunama-laser esifunda esiqinile angokwesiko ampontshwa amathoshi futhi anikeza isikhathi eside sokusebenza ngenxa yokuqina kwamalaser e-diode. Bayakwazi futhi ukukhiqiza imishayo ye-laser ezinzile futhi enembayo, ebalulekile ekusetshenzisweni okunemininingwane nokunemba okuphezulu.

Izicelo Ezibalulekile ze-CW Diode Pumped Solid State Laser:

1.I-Laser Diamond Cutting:

I-G2-A laser isebenzisa ukucushwa okujwayelekile kokuphindwa kabili: i-infrared input beam ku-1064 nm iguqulwa ibe igagasi elingu-532-nm eliluhlaza njengoba lidlula kukristalu elingaqondile. Le nqubo, eyaziwa ngokuthi i-frequency doubling noma i-second harmonic generation (SHG), iyindlela esetshenziswa kabanzi yokukhiqiza ukukhanya ngamaza amaza amafushane.

Ngokuphinda kabili imvamisa yokukhishwa kokukhanya kusuka ku-neodymium- noma i-ytterbium-based 1064-nm laser, i-laser yethu ye-G2-A ingakhiqiza ukukhanya okuluhlaza ku-532 nm. Le nqubo ibalulekile ekudaleni ama-lasers aluhlaza, avame ukusetshenziswa ezinhlelweni ezisukela ezikhombi ze-laser kuye kwezisetshenziswa eziyinkimbinkimbi zesayensi nezimboni, futhi adume endaweni yokusika i-Laser Diamond.

2. Ukucubungula Okubalulekile:

 Lawa ma-laser asetshenziswa kakhulu ezinhlelweni zokucubungula izinto ezifana nokusika, ukushisela, nokubhoboza izinsimbi nezinye izinto. Ukunemba kwazo okuphezulu kuzenza zilungele imiklamo nokusikeka okuyinkimbinkimbi, ikakhulukazi ezimbonini zezimoto, ze-aerospace, ne-electronics.

3. Izicelo Zokwelashwa:

Emkhakheni wezokwelapha, amalaser e-CW DPSS asetshenziselwa ukuhlinzwa okudinga ukunemba okuphezulu, njengokuhlinzwa kwamehlo (okufana ne-LASIK yokulungiswa kombono) kanye nezinqubo ezihlukahlukene zamazinyo. Ikhono lazo lokukhomba ngokunembile izicubu lizenza zibe usizo ekuhlinzeni okungavamisile.

4. Ucwaningo Lwesayensi:

Lawa ma-laser asetshenziswa ohlotsheni lwezinhlelo zesayensi, okuhlanganisa i-spectroscopy, i-particle image velocimetry (esetshenziswa ku-fluid dynamics), kanye ne-laser scanning microscopy. Okukhiphayo okuzinzile kubalulekile ekulinganisweni okunembile nokubhekwa ocwaningweni.

5. Ezokuxhumana:

Emkhakheni wezokuxhumana ngocingo, ama-laser e-DPSS asetshenziswa ezinhlelweni zokuxhumana ze-fiber optic ngenxa yekhono lazo lokukhiqiza uthango oluzinzile futhi olungaguquguquki, oludingekayo ukuze kudluliswe idatha kumabanga amade nge-optical fibers.

6. Ukuqoshwa kwe-Laser nokumaka:

Ukunemba nokusebenza kahle kwamalaser e-CW DPSS kuwenza afanelekele ukuqoshwa nokumaka inhlobonhlobo yezinto ezisetshenziswayo, okuhlanganisa izinsimbi, amapulasitiki, nezitsha zobumba. Ngokuvamile zisetshenziselwa ukwenza ibhakhodi, izinombolo ze-serial, kanye nezinto eziqondene nawe.

7. Ukuvikela Nokuvikeleka:

Lawa ma-laser athola izinhlelo zokusebenza ekuvikeleni ukuqokwa okuqondiwe, ukutholwa kobubanzi, nokukhanya kwe-infrared. Ukuthembeka nokunemba kwabo kubalulekile kulezi zindawo eziphakeme kakhulu.

8. Ukukhiqiza I-semiconductor:

Embonini ye-semiconductor, amalaser e-CW DPSS asetshenziselwa imisebenzi efana ne-lithography, i-annealing, nokuhlolwa kwama-wafers we-semiconductor. Ukunemba kwelaser kubalulekile ekudaleni izakhiwo ezincane kuma-semiconductor chips.

9. Ukuzijabulisa Nokubukisa:

Zibuye zisetshenziswe embonini yokuzijabulisa emibukisweni ekhanyayo nokuqagela, lapho ikhono lazo lokukhiqiza imishayo yokukhanya ekhanyayo futhi egxilile inenzuzo.

10. I-Biotechnology:

Ku-biotechnology, lawa ma-lasers asetshenziswa ezinhlelweni ezifana nokulandelana kwe-DNA nokuhlelwa kwamaseli, lapho ukunemba kwawo kanye nokukhishwa kwamandla okulawulwayo kubalulekile.

11. I-Metrology:

Ukuze uthole ukukalwa okunembayo nokuqondanisa kwezobunjiniyela nokwakha, amalaser e-CW DPSS anikeza ukunemba okudingekayo emisebenzini efana nokulinganisa, ukuqondanisa, kanye nokwenza iphrofayela.
