Laser ya CW DPSS ni iki? Isesengura ry'ibisobanuro

Umuraba uhoraho (CW):Ibi bivuga uburyo laser ikora. Muri CW mode, laser itanga urumuri rudahindagurika, bitandukanye na laser zikoresha pulse zitanga urumuri mu buryo butunguranye. CW laser zikoreshwa iyo hakenewe urumuri rudahindagurika, nko mu gukata, gusudira, cyangwa gukoresha icyuma.

Kuvoma Diode:Muri laser zikoresha diode, ingufu zikoreshwa mu gukangura laser zitangwa na diode za semiconductor laser. Izi diode zitanga urumuri rwinjizwa na laser, zigashimisha atome ziri muri zo kandi zigatuma zitanga urumuri ruhamye. Gukangura diode birakora neza kandi byizewe ugereranije n'uburyo bwa kera bwo gukangura, nka flashlamps, kandi bituma habaho imiterere ya laser iciriritse kandi irambye.

Laser yo mu rwego rwo hejuru:Ijambo "solid-state" risobanura ubwoko bw'uburyo bwo gukusanya umusaruro bukoreshwa muri laser. Bitandukanye na laser za gaze cyangwa liquid, laser za solid-state zikoresha ibikoresho bikomeye nk'uburyo bwo gukusanya. Ubu buryo busanzwe ni kristu, nka Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) cyangwa Ruby, igizwe n'ibintu bidasanzwe byo mu butaka bituma habaho urumuri rwa laser. Kristale ya doped niyo yongera urumuri kugira ngo rukore urumuri rwa laser.

Uburebure bw'amabara n'imikoreshereze:Lazeri za DPSS zishobora gusohora ku bunini butandukanye bw'uburebure, bitewe n'ubwoko bw'ibikoresho bya doping bikoreshwa muri kristu n'imiterere ya lazeri. Urugero, imiterere isanzwe ya lazeri ya DPSS ikoresha Nd:YAG nk'uburyo bwo gukuramo lazeri kuri 1064 nm muri spectrum ya infrared. Ubu bwoko bwa lazeri bukoreshwa cyane mu nganda mu gukata, gusudira, no gushyira ikimenyetso ku bikoresho bitandukanye.

Ibyiza:Lazeri za DPSS zizwiho ubwiza bwazo, imikorere yazo myiza, kandi zizewe. Zikoresha ingufu nke kurusha lazeri zisanzwe zikoreshwa n'amatara ya flash kandi zitanga igihe kirekire cyo gukora bitewe n'uko lazeri za diode ziramba. Zishobora kandi gukora imirasire ya laser ihamye kandi isobanutse neza, ibi bikaba ari ingenzi cyane mu gukoresha neza no mu buryo burambuye.

Imikoreshereze y'ingenzi ya CW Diode Pumped Solid State Laser:

1.Gukata Diyama hakoreshejwe Lazeri:

Lazeri ya G2-A ikoresha uburyo busanzwe bwo gukuba inshuro ebyiri: urumuri rw’umurasire wa infrared kuri 1064 nm ruhinduka umuraba w’icyatsi kibisi wa 532-nm iyo runyuze muri kristu idakoresha umurongo umwe. Ubu buryo, buzwi nka gukuba inshuro ebyiri cyangwa SHG ya kabiri, ni uburyo bukoreshwa cyane mu gutanga urumuri ku isanzure ry’uburebure rigufi.

Mu kongera inshuro ebyiri urumuri ruturuka kuri laser ya 1064-nm ikoresha neodymium cyangwa ytterbium, laser yacu ya G2-A ishobora gukora urumuri rw'icyatsi kibisi kuri 532 nm. Ubu buryo ni ingenzi mu gukora laser y'icyatsi kibisi, ikoreshwa cyane mu bikorwa bitandukanye kuva ku byuma bipima laser kugeza ku bikoresho bya siyansi n'inganda bigezweho, kandi ikaba ikunzwe cyane mu gace gacukura diyama muri laser.

2. Gutunganya ibikoresho:

 Izi laser zikoreshwa cyane mu gutunganya ibikoresho nko gukata, gusudira, no gucukura ibyuma n'ibindi bikoresho. Ubuhanga bwazo butuma ziba nziza cyane mu gushushanya no gukata ibintu mu buryo buhambaye, cyane cyane mu nganda zikora imodoka, indege n'ibikoresho by'ikoranabuhanga.

3. Ubusabe bwo Kwakira:

Mu rwego rw'ubuvuzi, imirasire ya CW DPSS ikoreshwa mu kubaga bisaba ubuhanga bwo hejuru, nko kubaga amaso (nka LASIK yo gukosora amaso) no mu buryo butandukanye bwo kuvura amenyo. Ubushobozi bwayo bwo kwibasira neza ingingo z'umubiri butuma igira akamaro mu kubaga gake cyane.

4. Ubushakashatsi bwa Siyansi:

Izi laser zikoreshwa mu buryo butandukanye bwa siyansi, harimo spectroscopy, velocimetry y'ishusho y'uduce (ikoreshwa mu mihindagurikire y'amazi), na microscopy ya laser scanning. Umusaruro wazo uhamye ni ingenzi kugira ngo habeho gupima neza no kwitegereza neza mu bushakashatsi.

5. Itumanaho:

Mu rwego rw'itumanaho, lazeri za DPSS zikoreshwa muri sisitemu y'itumanaho rya fiber optique bitewe n'ubushobozi bwazo bwo gukora urumuri ruhamye kandi ruhoraho, ibyo bikaba ari ngombwa mu kohereza amakuru mu ntera ndende binyuze muri fibre optique.

6. Gushushanya no gushyira ikimenyetso kuri laser:

Ubuhanga n'ubushobozi bwa laser za CW DPSS bituma zikoreshwa mu gushushanya no gushyira ibimenyetso ku bikoresho bitandukanye, harimo ibyuma, pulasitiki, na ceramic. Zikunze gukoreshwa mu gushushanya, gushyira mu byiciro no gushyira ibintu ku giti cyabyo.

7. Ubwunganizi n'umutekano:

Izi laser zibona uburyo bwo kwirwanaho mu kugaragaza intego, gushakisha aho ibintu biri, no kubona urumuri rwa infrared. Kwizerwa kwazo no gukora neza kwazo ni ingenzi cyane muri ibi bice bikomeye.

8. Gukora ibikoresho bya semiconductor:

Mu nganda za semiconductor, laser za CW DPSS zikoreshwa mu mirimo nka lithography, annealing, no kugenzura wafer za semiconductor. Ubuhanga bwa laser ni ingenzi mu gukora imiterere ya microscale kuri chips za semiconductor.

9. Imyidagaduro n'Imurikagurisha:

Zikoreshwa kandi mu nganda z'imyidagaduro mu bitaramo by'amatara no mu kwerekana amashusho, aho ubushobozi bwazo bwo gukora urumuri rwinshi kandi runini ari ingirakamaro.

10. Ikoranabuhanga mu by'ibinyabuzima:

Mu ikoranabuhanga rya biotechnology, izi laser zikoreshwa mu bikorwa nko gukurikirana ADN no gutondekanya utunyangingo, aho ubwiza bwazo n'ingufu zikoreshwa mu kugenzura ari ingenzi cyane.

11. Metrology:

Kugira ngo habeho gupima no guhuza neza ibintu mu buhanga n'ubwubatsi, laser za CW DPSS zitanga uburyo bwo gukora ibintu neza nko gupima, guhuza no gusesengura.
