Wafer yihuta cyane kandi ikora neza cyaneikoranabuhanga rya laser
Ingufu nyinshilaser yihuta cyanezikoreshwa cyane mu nganda zigezweho, mu ikoranabuhanga rigezweho, mu by’ikoranabuhanga riciriritse, mu buvuzi bw’ibinyabuzima, mu bijyanye n’ingabo z’igihugu no mu bya gisirikare, kandi ubushakashatsi bwa siyansi bujyanye nabyo ni ingenzi mu guteza imbere udushya mu by’ubumenyi n’ikoranabuhanga mu gihugu no mu iterambere ry’urwego rwo hejuru.sisitemu ya laserKubera ibyiza byayo by’ingufu nyinshi, ingufu nyinshi zo mu kirere n’ubwiza bw’imirasire y’amashanyarazi, irakenewe cyane muri fiziki ya attosecond, gutunganya ibikoresho n’izindi nzego za siyansi n’inganda, kandi yahangayikishijwe cyane n’ibihugu hirya no hino ku isi.
Mu minsi ishize, itsinda ry’abashakashatsi mu Bushinwa ryakoresheje ikoranabuhanga rya wafer module n’ikoranabuhanga ryo kongera imbaraga mu kongera imbaraga kugira ngo rigere ku musaruro mwiza (ubudahangarwa bwo hejuru, imbaraga nyinshi, ubwiza bwo hejuru, imikorere myiza cyane) wafer yihuta cyane.laserumusaruro. Binyuze mu gushushanya umwobo wa amplifier yo kuvugurura no kugenzura ubushyuhe bw'ubuso n'uburyo kristu ya disiki ihagaze neza mu mwobo, umusaruro wa lazeri uva mu ngufu za single pulse >300 μJ, ubugari bwa pulse <7 ps, imbaraga mpuzandengo >150 W uragerwaho, kandi ubushobozi bwo guhindura urumuri kuva ku mucyo kugera ku mucyo bushobora kugera kuri 61%, ari nabwo buryo bwo guhindura urumuri bwagutse cyane bwagaragajwe kugeza ubu. Ireme ry'umuraba M2 <1.06@150W, ubushobozi bwo guhagarara amasaha 8 RMS <0.33%, iyi ntambwe igaragaza intambwe ikomeye mu gukoresha lazeri ya wafer ikora neza cyane, izatanga amahirwe menshi yo gukoresha lazeri ikora cyane.

Uburyo bwo kongera gusubiramo inshuro nyinshi, uburyo bwo kongera imbaraga za wafer
Imiterere ya amplifier ya laser ya wafer igaragara ku Ishusho ya 1. Irimo isoko y'imbuto za fibre, umutwe wa laser woroheje hamwe n'umwobo wo kongera kuvugurura. Imbuto za oscillator za fibre za ytterbium zifite imbaraga mpuzandengo ya 15 mW, uburebure bw'umurambararo bwa 1030 nm, ubugari bwa pulse bwa 7.1 ps n'umuvuduko wo gusubiramo wa 30 MHz zakoreshejwe nk'isoko y'imbuto. Umutwe wa laser ya wafer ukoresha kristalo ya Yb: YAG yakozwe mu rugo ifite umurambararo wa mm 8.8 n'ubugari bwa µm 150 na sisitemu yo gupompa ya 48-stroke. Isoko y'ipompo ikoresha umurongo wa zero-phonon LD ufite uburebure bwa 969 nm bworoshye, bigabanya ikibazo cya quantum kugeza kuri 5.8%. Imiterere yihariye yo gukonjesha ishobora gukonjesha neza kristalo ya wafer no kwemeza ko umwobo wo kongera kuvugurura uhamye. Umwobo wo kongera kuvugurura ugizwe na Pockels cells (PC), Thin Film Polarizers (TFP), Quarter-Wave Plates (QWP) na resonator ifite ubushobozi bwo gushimangira. Ibyuma bitandukanya urumuri bikoreshwa mu gukumira urumuri rwinshi rwangiza isoko y'imbuto. Imiterere y'ibyuma bigabanya urumuri igizwe na TFP1, Rotator na Half-Wave Plates (HWP) ikoreshwa mu gutandukanya imbuto zinjira n'ibyuma bigabanya urusaku. Ibyuma bigabanya urusaku byinjira mu cyumba cyo kongera urusaku binyuze muri TFP2. Kristale ya Barium metaborate (BBO), PC, na QWP bihurira hamwe bigashyira imbaraga mu gukora icyuma gikoresha ingufu nyinshi kuri PC kugira ngo gifate neza urusaku rw'imbuto no kurukwirakwiza mu mwobo. Ibyuma byifuzwa birazunguruka mu mwobo kandi bikongerwa neza mu gihe cyo kugaruka no kugaruka binyuze mu guhindura neza igihe cyo gukandagira mu gasanduku.
Amplifier yo kuvugurura wafer igaragaza umusaruro mwiza kandi izagira uruhare runini mu nganda zikora ibintu byo mu rwego rwo hejuru nka lithography ya ultraviolet extreme, attosecond pump source, 3C electronics, n'imodoka nshya zikoresha ingufu. Muri icyo gihe, ikoranabuhanga rya wafer laser ryitezwe gukoreshwa ku binyabiziga binini bikomeye cyane.ibikoresho bya laser, itanga uburyo bushya bwo kugerageza bwo gukora no gutahura neza ibintu ku gipimo cy’ikirere cya nanoscale na femtosecond time scale. Intego yo guhaza ibyifuzo by’ingenzi by’igihugu, itsinda ry’umushinga rizakomeza kwibanda ku guhanga udushya mu ikoranabuhanga rya laser, kurushaho guca intege mu gutegura kristu za laser zifite imbaraga nyinshi, no kunoza neza ubushobozi bw’ubushakashatsi n’iterambere ryigenga ry’ibikoresho bya laser mu nzego z’amakuru, ingufu, ibikoresho byo mu rwego rwo hejuru n’ibindi.
