Iyini i-laser ye-CW DPSS? Incazelo Incazelo

Igagasi Eliqhubekayo (CW):Lokhu kubhekisela kwimodi yokusebenza kwe-laser. Kumodi ye-CW, i-laser ikhipha ukukhanya okuzinzile nokungaguquguquki, ngokungafani nama-laser ashukunyiswayo akhipha ukukhanya ngokuqhuma. Ama-laser e-CW asetshenziswa lapho kudingeka ukukhanya okuqhubekayo nokuzinzile, njengasekucubunguleni, ekushiseni, noma ekuqopheni.

Ukupompa kwe-diode:Kuma-laser adonswa yi-diode, amandla asetshenziswa ukuvusa i-laser medium anikezwa ama-diode e-laser e-semiconductor. Lawa ma-diode akhipha ukukhanya okumuncwa yi-laser medium, okuvusa ama-athomu angaphakathi kwawo futhi kuwavumele ukuthi akhiphe ukukhanya okuqondile. Ukupompa kwe-diode kusebenza kahle futhi kuthembekile uma kuqhathaniswa nezindlela ezindala zokupompa, njengezibani ezikhanyayo, futhi kuvumela imiklamo ye-laser emincane futhi eqinile.

I-Laser Yesimo Esiqinile:Igama elithi "i-solid-state" libhekisela ohlotsheni lwe-gain medium esetshenziswa ku-laser. Ngokungafani nama-gas noma ama-liquid laser, ama-solid-state laser asebenzisa izinto eziqinile njenge-medium. Le medium ngokuvamile iyikristalu, njenge-Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) noma i-Ruby, exutshwe nezinto ezingavamile zomhlaba ezivumela ukukhiqizwa kokukhanya kwe-laser. Ikristalu exutshwe yiyo ekhulisa ukukhanya ukuze kukhiqizwe umsebe we-laser.

Ubude be-Wavelength kanye nezicelo:Ama-laser e-DPSS angakhipha ngamaza ahlukahlukene, kuye ngohlobo lwezinto zokusebenzisa izidakamizwa ezisetshenziswa kukristalu kanye nomklamo we-laser. Isibonelo, ukucushwa okuvamile kwe-laser ye-DPSS kusebenzisa i-Nd:YAG njengendlela yokuthola inzuzo yokukhiqiza i-laser ku-1064 nm ku-spectrum ye-infrared. Lolu hlobo lwe-laser lusetshenziswa kabanzi ezinhlotsheni zezimboni zokusika, ukushisela, kanye nokumaka izinto ezahlukahlukene.

Izinzuzo:Ama-laser e-DPSS aziwa ngekhwalithi yawo ephezulu yemisebe, ukusebenza kahle, kanye nokuthembeka. Asebenzisa amandla amaningi kune-laser yendabuko yesimo esiqinile ekhishwa ngama-flashlight futhi anikeza isikhathi eside sokusebenza ngenxa yokuqina kwama-laser e-diode. Ayakwazi futhi ukukhiqiza imisebe ye-laser eqinile futhi enembile, okubalulekile ekusetshenzisweni okuningiliziwe nokunembile.

Izicelo Eziyinhloko ze-CW Diode Pumped Solid State Laser:

1.Ukusikwa Kwedayimane Nge-Laser:

I-laser ye-G2-A isebenzisa ukucushwa okuvamile kokuphindaphinda imvamisa: umsebe wokufaka we-infrared ku-1064 nm uguqulwa ube yigagasi eliluhlaza elingu-532-nm njengoba lidlula kukristalu elingelona umugqa. Le nqubo, eyaziwa ngokuthi ukuphindaphindwa kwemvamisa noma isizukulwane sesibili se-harmonic (SHG), iyindlela eyamukelwa kabanzi yokukhiqiza ukukhanya ngamaza amafushane.

Ngokuphinda kabili imvamisa yokukhishwa kokukhanya okuvela ku-laser engu-1064-nm esekelwe ku-neodymium noma i-ytterbium, i-laser yethu ye-G2-A ingakhiqiza ukukhanya okuluhlaza ku-532 nm. Le ndlela ibalulekile ekudaleni ama-laser aluhlaza, avame ukusetshenziswa ezinhlelweni ezisukela kuma-laser pointers kuya kumathuluzi esayensi nezimboni ayinkimbinkimbi, futhi athandwa kakhulu endaweni yokusika idayimane ye-Laser.

2. Ukucubungula Izinto:

 Lawa ma-laser asetshenziswa kakhulu ekucubungulweni kwezinto ezifana nokusika, ukushisela, kanye nokubhoboza izinsimbi nezinye izinto. Ukunemba kwawo okuphezulu kuwenza afaneleke kakhulu emiklamo eyinkimbinkimbi kanye nokusika, ikakhulukazi embonini yezimoto, yezindiza kanye neye-elekthronikhi.

3. Izicelo Zezokwelapha:

Emkhakheni wezokwelapha, ama-laser e-CW DPSS asetshenziselwa ukuhlinzwa okudinga ukunemba okuphezulu, njengokuhlinzwa kwamehlo (njenge-LASIK yokulungisa umbono) kanye nezinqubo ezahlukahlukene zamazinyo. Ikhono lawo lokuqondisa ngqo izicubu lenza zibe usizo ekuhlinzeni okungangenisi kakhulu.

4. Ucwaningo Lwesayensi:

Lawa ma-laser asetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza zesayensi, okuhlanganisa i-spectroscopy, i-particle image velocimetry (esetshenziswa ku-fluid dynamics), kanye ne-laser scanning microscopy. Umphumela wawo ozinzile ubalulekile ekulinganisweni nasekubonweni okunembile ocwaningweni.

5. Ezokuxhumana:

Emkhakheni wezokuxhumana, ama-laser e-DPSS asetshenziswa ezinhlelweni zokuxhumana ze-fiber optic ngenxa yekhono lawo lokukhiqiza umsebe ozinzile nongaguquguquki, okudingekayo ekudluliseni idatha emabangeni amade ngemicu ye-optical.

6. Ukuqoshwa Nokumakwa Nge-Laser:

Ukunemba nokusebenza kahle kwama-laser e-CW DPSS kuwenza afanelekele ukuqopha nokumaka izinto eziningi ezahlukene, okuhlanganisa izinsimbi, ipulasitiki, kanye nezinto zobumba. Avame ukusetshenziswa ekubhaleni amabhakhodi, ukubhala izinombolo zochungechunge, kanye nokwenza izinto zibe ngezomuntu siqu.

7. Ukuvikela Nokuphepha:

Lawa ma-laser athola izinhlelo zokusebenza zokuzivikela ekuchazeni okuqondiwe, ekutholeni ibanga, kanye nokukhanya kwe-infrared. Ukuthembeka kwawo kanye nokunemba kwawo kubalulekile kulezi zindawo ezisengozini enkulu.

8. Ukukhiqizwa Kwe-semiconductor:

Embonini ye-semiconductor, ama-laser e-CW DPSS asetshenziselwa imisebenzi efana ne-lithography, i-annealing, kanye nokuhlolwa kwama-wafer e-semiconductor. Ukunemba kwe-laser kubalulekile ekudaleni izakhiwo ze-microscale kuma-chip e-semiconductor.

9. Ezokuzijabulisa Nokuboniswa:

Zisetshenziswa futhi embonini yezokuzijabulisa emibukisweni yokukhanya kanye nemibukiso, lapho ikhono lazo lokukhiqiza imisebe yokukhanya ekhanyayo negxilile lizuzisa khona.

10. I-Biotechnology:

Ku-biotechnology, lawa ma-laser asetshenziswa ezinhlelweni ezifana nokulandelana kwe-DNA kanye nokuhlela amaseli, lapho ukunemba kwawo kanye nokukhishwa kwamandla okulawulwayo kubalulekile.

11. I-Metrology:

Ukuze kulinganiswe kahle futhi kulungiswe kahle kwezobunjiniyela nakwezokwakha, ama-laser e-CW DPSS anikeza ukunemba okudingekayo emisebenzini efana nokulinganisa, ukulinganisa, kanye nokufaka iphrofayili.
