Chii chinonzi CW DPSS laser? Tsananguro Kupatsanurwa

Mafungu Anoenderera Mberi (CW):Izvi zvinoreva maitiro ekushanda kwelaser. MuCW mode, laser inoburitsa chiedza chakasimba, chisingachinji, kusiyana nemapulsed lasers anoburitsa chiedza mukuputika. CW lasers dzinoshandiswa kana chiedza chichibuda nguva dzose, chakasimba, senge pakucheka, kusanganisa, kana kugadzira zvishongo.

Kupomba Diode:Muma laser anopombwa ne diode, simba rinoshandiswa kumutsa laser medium rinopihwa nema semiconductor laser diodes. Aya ma diode anoburitsa chiedza chinotorwa ne laser medium, zvichifadza maatomu ari mukati mawo uye zvichivabvumira kuburitsa chiedza chakabatana. Kupomba ma diode kunoshanda uye kwakavimbika zvichienzaniswa nenzira dzekare dzekupomba, senge flashlamps, uye kunobvumira magadzirirwo e laser akatetepa uye anogara kwenguva refu.

Laser Yemamiriro Akasimba:Izwi rekuti "solid-state" rinoreva rudzi rwe gain medium inoshandiswa mu laser. Kusiyana nema gas kana liquid lasers, ma solid-state lasers anoshandisa solid material se medium. Iyi medium inowanzova crystal, senge Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) kana Ruby, ine zvinhu zvisingawanzoitiki zvinoita kuti chiedza che laser chigadzike. Iyo doped crystal ndiyo inowedzera chiedza kuti chigadzire laser beam.

Marefu eWavelength uye Mashandisirwo:Malaser eDPSS anogona kuburitsa mawavelength akasiyana-siyana, zvichienderana nerudzi rwezvinhu zvinoshandiswa mukristaro uye dhizaini yelaser. Semuenzaniso, dhizaini yelaser yeDPSS inoshandisa Nd:YAG senzira yekuwana nayo laser pa1064 nm mu infrared spectrum. Rudzi urwu rwelaser runoshandiswa zvakanyanya mumaindasitiri ekucheka, kusanganisa, uye kuisa mamaki pazvinhu zvakasiyana-siyana.

Zvakanakira:Malaser eDPSS anozivikanwa nekunaka kwawo, kushanda zvakanaka, uye kuvimbika. Anoshandisa simba shoma kupfuura malaser echinyakare e solid-state anopombwa nemwenje yeflash uye anopa hupenyu hurefu hwekushanda nekuda kwekugara kwenguva refu kwemalaser ediode. Anokwanisawo kugadzira malaser akasimba uye akanyatsojeka, izvo zvakakosha pakushandisa zvakadzama uye nemazvo.

Mashandisirwo Akakosha eCW Diode Pumped Solid State Laser:

1.Kucheka kweDaimondi neLaser:

Laser yeG2-A inoshandisa nzira yakajairika yekudzokorodza frequency: danda reinfrared input pa1064 nm rinoshandurwa kuita wave yegirini ye532-nm parinopfuura nepakati pekristaro isina mutsara. Maitiro aya, anozivikanwa se frequency doubling kana second harmonic generation (SHG), inzira inoshandiswa zvakanyanya yekugadzira chiedza pahurefu hwema wavelengths hupfupi.

Nekuwedzera kaviri frequency yekubuda kwechiedza kubva kune neodymium- kana ytterbium-based 1064-nm laser, laser yedu yeG2-A inogona kugadzira chiedza chegirini pa532 nm. Iyi nzira yakakosha pakugadzira magreen lasers, ayo anowanzo shandiswa mumashandisirwo akasiyana kubva kuma laser pointers kusvika kune zvishandiso zvesainzi uye zvemaindasitiri, uye zvakare anonyanya kufarirwa muLaser Diamond Cutting Area.

2. Kugadziriswa Kwezvinhu:

 Malaser aya anoshandiswa zvakanyanya mukugadzirisa zvinhu zvakaita sekucheka, kusanganisa, uye kuboora simbi nezvimwe zvinhu. Kunyatsoshanda kwawo kunoita kuti akwanise kugadzirwa nekucheka zvinhu zvakaoma, kunyanya muindasitiri yemotokari, yendege, uye yemagetsi.

3. Mafomu Ekushandisa Mukurapa:

Mukurapa, ma laser eCW DPSS anoshandiswa pakuvhiya kunoda kunyatsojeka, sekuvhiya maziso (senge LASIK yekugadzirisa kuona) uye nzira dzakasiyana-siyana dzekurapa mazino. Kugona kwavo kunanga nyama zvakananga kunoita kuti dzive dzinokosha mukuvhiya kusingapindi zvakanyanya.

4. Tsvagiridzo yeSainzi:

Malaser aya anoshandiswa mumabasa akasiyana-siyana esainzi, anosanganisira spectroscopy, particle image velocimetry (inoshandiswa mu fluid dynamics), uye laser scanning microscopy. Kubuda kwawo kwakasimba kwakakosha pakuyera nemazvo uye kucherechedza mukutsvaga.

5. Kutaurirana:

Munyaya dzekutaurirana, ma DPSS lasers anoshandiswa mumasisitimu ekutaurirana ne fiber optic nekuda kwekukwanisa kwawo kugadzira danda rakagadzikana uye rinowirirana, iro rinodiwa pakutumira data kure kure kuburikidza ne optical fibers.

6. Kunyora neLaser:

Kunyatsojeka uye kushanda zvakanaka kwemalaser eCW DPSS kunoita kuti akwanise kuveza nekumaka zvinhu zvakasiyana-siyana, zvinosanganisira simbi, mapurasitiki, uye zviumbwa zvedongo. Anowanzoshandiswa pakugadzira mabarcode, kunyora manhamba, uye kugadzira zvinhu zvinoenderana nemunhu.

7. Dziviriro neKuchengetedzwa:

Malaser aya anowana mashandisirwo ekudzivirira chinangwa, kutsvaga nzvimbo, uye kuvhenekesa kwe infrared. Kuvimbika kwavo uye kurongeka kwavo kwakakosha munzvimbo idzi dzine njodzi huru.

8. Kugadzira Semiconductor:

Muindasitiri yesemiconductor, malaser eCW DPSS anoshandiswa pamabasa akadai se lithography, annealing, uye kuongorora mawafer esemiconductor. Kunyatsojeka kwelaser kwakakosha pakugadzira maumbirwo e microscale pamaserumondi chips.

9. Varaidzo neZviratidzwa:

Dzinoshandiswawo muindasitiri yevaraidzo pakuratidzira chiedza nekuratidzira, uko kugona kwadzo kugadzira chiedza chakajeka uye chakasimba kunobatsira.

10. Biotechnology:

Mu biotechnology, ma laser aya anoshandiswa mukushandiswa kwakadai seDNA sequencing uye masero sorting, uko kunyatsojeka kwavo uye simba rinodzorwa rinobuda zvakakosha.

11. Metrology:

Kuti zviyereswe uye zvienderane nemazvo muinjiniya nekuvaka, malaser eCW DPSS anopa kururama kunodiwa pamabasa akadai sekuyera, kuenderana, uye kuongorora.
