Uburyo bwo gukuramo ibara rya Laser ni iki?

Uburyo bwo gukuraho urumuri hakoreshejwe uburyo bwa laser ni ibikoresho byongera urumuri binyuze mu ibyuka bishyushye. Iyo atome cyangwa molekile z'ubwo buryo zihujwe n'ingufu nyinshi, zishobora gutanga fotoni z'uburebure runaka iyo zigarutse ku rwego rwo hasi rw'ingufu. Ubu buryo bwongera urumuri runyura muri ubwo buryo, ari nabyo by'ingenzi mu mikorere ya laser.

Uburyo Busanzwe bwo Kunguka ni ubuhe?

Uburyo bwo kunguka bushobora guhindurwa, harimoimyuka, ibinyobwa (irangi), ibintu bikomeye(amakristale cyangwa indorerwamo zivanze na iyoni z'icyuma zidasanzwe cyangwa zihindagurika), hamwe na semiconductors.Lazeri za leta ikomeyeUrugero, akenshi bakoresha kristu nka Nd: YAG (Neodymium-doped Yttrium Aluminium Garnet) cyangwa indorerwamo zirimo ibintu bidasanzwe. Laser zikoresha irangi zikoresha amarangi y’umwimerere ashongeshejwe mu bintu bishongesha, naho laser zikoresha imyuka cyangwa uruvange rwa gazi.

Inkoni za laser (kuva ibumoso ujya iburyo): Ruby, Alexandrite, Er:YAG, Nd:YAG

Itandukaniro riri hagati ya Nd (Neodymium), Er (Erbium), na Yb (Ytterbium) nk'uburyo bwo gukusanya

ahanini bifitanye isano n'uburebure bw'ingufu zisohora, uburyo bwo kohereza ingufu, n'ikoreshwa ryazo, cyane cyane mu bijyanye n'ibikoresho bya laser bya doped.

Uburebure bw'imiraba isohora umwuka:

- Er: Erbium ikunze gusohora kuri 1.55 µm, ikaba iri mu gace karinda amaso kandi ikaba ingirakamaro cyane mu itumanaho bitewe n'igihombo cyayo gito mu migozi y'urumuri (Gong et al., 2016).

- Yb: Ytterbium ikunze gutanga hagati ya µm 1.0 na 1.1, bigatuma ikoreshwa mu buryo butandukanye, harimo na lazeri zifite imbaraga nyinshi na amplifiers. Yb ikunze gukoreshwa nk'ikintu gituma Er yongera ubushobozi bw'ibikoresho bya Er binyuze mu kohereza ingufu kuva kuri Yb zijya kuri Er.

- Nd: Ibikoresho birimo Neodymium bikunze gusohora hafi µm 1.06. Urugero, Nd:YAG izwiho imikorere myiza kandi ikoreshwa cyane mu byuma bya laser byo mu nganda no mu buvuzi (Y. Chang et al., 2009).

Uburyo bwo kohereza ingufu:

- Er na Yb Co-doping: Co-doping ya Er na Yb mu buryo bw'umwuka ni ingirakamaro mu kongera imyuka iri hagati ya µm 1.5-1.6. Yb ikora nk'ikintu gifasha Er kumererwa neza binyuze mu kwinjiza urumuri rwa pompe no kohereza ingufu kuri iyoni za Er, bigatuma imyuka yoherezwa mu buryo bwiyongera mu itumanaho. Uku guhererekanya ingufu ni ingenzi mu mikorere ya amplifiers za fibre za Er (EDFA) (DK Vysokikh et al., 2023).

- Nd: Nd ntabwo ikenera sensitizer nka Yb muri sisitemu za Er-doped. Ingufu za Nd zikomoka ku kwinjiza kwayo urumuri rwa pompe mu buryo butaziguye no ku isohoka ryayo nyuma y’aho iturutse, bigatuma iba uburyo bworoshye kandi bunoze bwo gukuramo urumuri rwa laser.

Porogaramu:

- Er:Ikoreshwa cyane cyane mu itumanaho bitewe n'uko isohora 1.55 µm, ibyo bikaba bihura n'igihe gito cyo gutakaza fibre optique ya silica. Ibyuma byo gukusanya amashanyarazi bya Er-doped ni ingenzi cyane ku byuma bitanga amplifier na lazeri muri sisitemu y'itumanaho rya fibre optique ikora kure.

- Yb:Ikunze gukoreshwa mu gukoresha ingufu nyinshi bitewe n'imiterere yayo yoroheje y'ikoranabuhanga ituma habaho gukoresha neza diode pumping no gutanga ingufu nyinshi. Ibikoresho bya Yb nabyo bikoreshwa mu kunoza imikorere ya sisitemu za Er-doped.

- Nd: Ikwiriye cyane gukoreshwa mu buryo butandukanye, kuva ku gukata no gusudira mu nganda kugeza kuri laser zo kwa muganga. Laser za Nd:YAG zihabwa agaciro cyane kubera imikorere yazo, imbaraga, n'ubushobozi bwazo bwo gukora ibintu bitandukanye.

Kuki twahisemo Nd:YAG nk'uburyo bwo gukuramo umusaruro muri laser ya DPSS?

Lazeri ya DPSS ni ubwoko bwa lazeri bukoresha uburyo bwo gupima ibintu bukoresha ikoranabuhanga rya solid-state gain (nka Nd: YAG) bukoreshwa na diode ya lazeri ya semiconductor. Iri koranabuhanga ryemerera lazeri nto kandi zikora neza zishobora gukora imirasire myiza mu buryo bugaragara no mu buryo bwa infrared. Ku nkuru irambuye, ushobora gutekereza gushakisha mu bubiko bw'amakuru bwa siyansi cyangwa abasohora ibitabo kugira ngo ubone isuzuma ryimbitse ku ikoranabuhanga rya lazeri ya DPSS.

Nd:YAG ikunze gukoreshwa nk'uburyo bwo gukuramo umusaruro muri module za laser zikoreshwa na semiconductor kubera impamvu zitandukanye, nk'uko byagaragajwe n'ubushakashatsi butandukanye:

1. Ingufu nyinshi n'umusaruro w'amashanyarazi: Igishushanyo n'ishusho bya module ya laser ya Nd:YAG ya diode yakozwe na diode byagaragaje imikorere myiza cyane, aho laser ya Nd:YAG ya diode yakozwe na diode itanga imbaraga mpuzandengo za 220 W mu gihe igumana ingufu zidahinduka kuri buri terambere mu ntera nini y'umuvuduko. Ibi bigaragaza imikorere myiza n'ubushobozi bwo gutanga ingufu nyinshi za laser ya Nd:YAG iyo ikozwe na diode (Lera et al., 2016).
2. Guhindura imikorere no kwizerwa: Ibikoresho bya Nd:YAG byagaragaye ko bikora neza ku burebure butandukanye bw'uburebure, harimo n'uburebure bw'uburebure butabangamira amaso, hamwe n'ubushobozi bwo hejuru bwo kuva kuri optique kugera kuri optique. Ibi bigaragaza ubuhanga bwa Nd:YAG mu gukora ibintu bitandukanye no kwizera nk'uburyo bwo gukura umusaruro mu buryo butandukanye bwa laser (Zhang et al., 2013).
3. Kuramba n'ubwiza bw'umurabyo: Ubushakashatsi kuri lazeri ya Nd:YAG ikora neza cyane, ikoresha diode, bwagaragaje ko iramba kandi ikora neza, bigaragaza ko Nd:YAG ikwiriye gukoreshwa isaba amasoko ya lazeri aramba kandi yizewe. Ubushakashatsi bwagaragaje ko ikora igihe kirekire, ifite amasasu arenga 4.8 x 10^9 nta kwangirika kw'amatara, ikomeza kugira ubwiza bwiza bw'imirasire (Coyle et al., 2004).
4. Umurimo uhoraho wo gukoresha umuraba uhoraho cyane:Ubushakashatsi bwagaragaje imikorere myiza cyane ya laser za Nd:YAG (CW), bugaragaza ko zikora neza cyane nk'uburyo bwo gukura umusaruro muri sisitemu za laser zikoresha diode. Ibi birimo kugera ku buhanga bwo guhindura urumuri mu buryo buhanitse no gukora neza mu miterere y'imirasire, bishimangira ko Nd:YAG ikwiriye gukoreshwa muri laser zikoresha ubuhanga bwo hejuru (Zhu et al., 2013).

Uruvange rw'imikorere myiza, ingufu zisohoka, ubushobozi bwo gukora neza, kwizerwa, kuramba, n'ubwiza bw'imirasire myiza bituma Nd:YAG iba uburyo bwiza bwo gukuramo ibintu muri module za laser zikoreshwa na semiconductor mu buryo butandukanye.
