RPMC Inganda picosekond laser neoMOS-70ps

Incamake y'ibicuruzwa n'amateka ya tekiniki

neoMOS-70ps ni intangarugero idasanzwe ya sisitemu yo mu rwego rwa picosekond ya laser yakozwe na neoLASE yo mu Budage, kandi ni umunyamuryango wa neoMOS ultrashort pulse laser. Urukurikirane rurimo moderi zifite ubugari butandukanye bwa pulse, kuva femtosekond neoMOS 700fs kugeza picosecond neoMOS 10ps na neoMOS 70ps, ikora ultrashort pulse laser igisubizo7. neoMOS-70ps yateguwe byumwihariko kubidukikije bikomeza kubyara inganda, bihuza tekinoroji ya fibre oscillator yubuhanga hamwe nubwubatsi bukomeye-bukomeye bwa amplifier yubatswe, kandi bugaragaza imikorere idasanzwe mubijyanye na micromachining neza.

Duhereye ku nkomoko ya tekiniki, urukurikirane rwa neoMOS rugereranya kwirundanya kwumwuga wa neoLASE mubijyanye na lazeri ikomeye, kandi filozofiya yayo ishushanya ishimangira uburinganire hagati y "kwizerwa" no "kubungabunga bike" 1. Ugereranije na sisitemu gakondo ya ultrafast, neoMOS-70ps ireka tekinoroji ya CPA (chirped pulse amplification) ikora kandi igakoresha imiterere yoroshye kandi ikora neza ya MOPA (master oscillator power amplifier), itagabanya gusa ingano ya sisitemu, ahubwo inatezimbere cyane imikorere yo guhindura ingufu. Iki gishushanyo mbonera gisubiza ibyifuzo byihutirwa byinganda kugirango miniaturizasi no guhuza ibikoresho, bituma ubunini bwumutwe wa laser bugenzurwa kuri 330mm × 220mm × 90mm (verisiyo ya 15W), byorohereza cyane guhuza sisitemu.

Ihiganwa ryibanze rya neoMOS-70ps rigaragarira mubikorwa byinganda-ndende. Ibikoresho byateguwe kugirango bikore 24/7 bikomeza, kandi igihe kiri hagati yo kunanirwa (MTBF) kirenze kure icy'ibikoresho byo mu rwego rwa laboratoire, bitewe n'ibishushanyo mbonera by'ibice by'ingenzi hamwe n'ibizamini bikomeye byo kurwanya ibidukikije7. Sisitemu ya laser ikoresha ubwubatsi bwa modular, cyane cyane harimo ibice bitanu: isoko yimbuto (fibre oscillator), preamplifier, amplifier nyamukuru, generator ihuza (itabishaka) hamwe nigice cyo kugenzura. Muri byo, inkomoko y'imbuto ishingiye ku kuvoma laser diode yizewe kugirango itange picosekond ya mbere; icyiciro cya amplifier gikoresha tekinoroji ya leta ikomeye kugirango yizere ubudahemuka bwimiterere ya pulse mugihe cyo kongera ingufu.

Urebye uko isoko rihagaze, neoMOS-70ps igamije cyane cyane murwego rwo gutunganya ibintu neza, harimo ariko ntibigarukira gusa ku bicuruzwa bifotora na elegitoroniki, kwerekana ibirahure, hamwe n’umutekano hamwe n’ibimenyetso byo gushushanya. Muri utwo turere, ubugari bwa 70ps butanga ubushyuhe bwiza bwibasiwe na zone mugihe wirinze kugorana nigiciro cya ultrashort pulses (nka laseri ya femtosekond). Lazeri ishyigikira igipimo cyisubiramo cyoroshye (kuva kuri imwe kugeza kuri 80MHz) hamwe no kugenzura ingufu za pulse (kugeza kuri 250μJ), zishobora guhuza ibikenewe bitandukanye.

Ibipimo bya tekiniki nibiranga imikorere

Lazeri ya neoMOS-70ps picosecond ifite imikorere myiza mubipimo byinshi bya tekiniki kubera igishushanyo mbonera cyayo cya tekinoroji, yujuje byimazeyo ibikenerwa mu gutunganya neza inganda. Gusobanukirwa byimbitse ibi bipimo bya tekiniki ningirakamaro muguhitamo ibikoresho, guteza imbere inzira no guhuza sisitemu. Iki gice kizasesengura ibipimo fatizo bya laser hamwe nubusobanuro bwa tekiniki inyuma yabo kuburyo burambuye kugirango bifashe abakoresha gusobanukirwa neza ibiranga ibikoresho.

Ibiranga umusaruro wibanze

Uburebure bwo hagati bwa neoMOS-70ps ni 1064nm, ikaba iri hafi ya-infragre ya spécran. Uburebure bwumurongo bufite uburyo bukwiye bwo kwinjiza ibintu bitandukanye byinganda, kandi birashobora guhinduka neza mumucyo wicyatsi (532nm) cyangwa urumuri ultraviolet (355nm / 266nm) binyuze mumashanyarazi adafite umurongo kugirango byuzuze ibisabwa byihariye24. Laser itanga impuzandengo yo gusohora ingufu za 15W, ni urwego ruciriritse-ruri hejuru murwego rwa picosekond kandi birahagije kubikorwa byinshi bya micromachining. Ingufu zayo imwe ishobora kugera kuri 250μJ, itanga ingwate ihagije yo gutunganya ibikoresho byinjira cyane.

Ubugari bwa pulse ni ishingiro ryizina ningenzi biranga neoMOS-70ps, igenzurwa neza kuri picosekond 70 (femtosekond 70.000) 4. Ubugari bwa pulse buringaniza neza gutunganya neza uburyo bwo gutunganya no kugorana kwa sisitemu - ugereranije na lazeri ya nanosekond, zone yibasiwe nubushyuhe iragabanuka cyane, kandi ibyago byo kwangirika kwa optique biterwa nimbaraga zikomeye cyane za lazeri femtosekond biririndwa. Lazeri ishyigikira intera nini yo gusubiramo inshuro nyinshi kuva imyuka ihumanya ikirere ikagera kuri 80MHz, kandi abayikoresha barashobora guhitamo bakurikije uburyo bwo gutunganya neza nibisabwa2. Birakwiye ko tumenya ko igikoresho gishobora kuba gifite "Burst mode" (gari ya moshi ya gari ya moshi), ishobora kugera ku musaruro ukurikiranye utabanje gukururwa hanze kugirango uhuze ibikenewe bidasanzwe byo gutunganya ibikoresho.
