Chii chinonzi cryogenic laser

Pfungwa yeLasers inoshanda pakudziya yakadzika haisi itsva: Iyo yechipiri laser munhoroondo yaive CRYGENIC. Pakutanga, pfungwa yacho yaive yakaoma kuwana tembiricha yekuisa tembiricha, uye kushingairira kwebasa rakadzika-tembiricha kwakatanga mu1990 nekuvandudzwa kwesimba repamusoro-sosi uye amplifiers.

Mune simba rakakwiriralaser zvinyorwa, inokonzeresa yakadaro seyakasimudzirwa kurasikirwa, iyo thermal lens kana laser Crystal kukotama kunogona kukanganisa maitiro eTsime Renje. Kuburikidza nekudziya kwekushisa, zvakawanda zvinokuvadza zvinokuvadza zvinogona kudzvanywa zvinobudirira, kureva kuti, iyo yekuwana svikiro inoda kutonhorerwa kusvika ku77k kana kunyange 4k. Mhedzisiro inotonhorera inonyanya kusanganisira:

Hunhu hwehunhu hwenyika hwesvikiro hunorambidzwa zvikuru, kunyanya nekuti nzira yemahara yetambo yakawedzera. Nekuda kweizvozvo, tembiricha yekudziya inodonha zvakanyanya. Semuenzaniso, kana tembiricha yakaderedzwa kubva 300k kusvika ku77k, iyo inobata mufambiro weiyo Yag Crystal inowedzera nechinhu cheanomwe.

Iyo inopisa yakashata coefficient zvakare inoderera zvakapusa. Izvi, pamwe nekuderedzwa mune tembiricha tembiricha, inoguma yakavezwa inodzora mari yekusimbisa uye saka mukana wakaderedzwa wekushushikana.

Iyo thermo-Optical coefficient yakaderedzwawo, kuwedzera kuderedza iyo inowedzera iyo lens.

Kuwedzera kweyakaora chikamu chevhu chevhu risina kujairika pasi pePasi rinodaira nekuda kwekuderera kwekuwedzera kwakaguma nemhedzisiro yekukanganisa. Naizvozvo, simba rekutonga rakaderedzwa uye laser kuwana kunowedzera. Naizvozvo, chikumbaridzo pombi pombi inoderedzwa, uye ipfupi pulses inogona kuwanikwa kana iyo q switch iri kushanda. Nekuwedzera kutururwa kweiyo yekubuda pamwe chete, kunyatsobudirira kunogona kuvandudzwa, saka iyo parasitic cavity kurasikirwa kunova kushoma.

Nhamba yemakiromita yehuwandu hwakareba huwandu hweiyo quasi-matatu-level-level fund Svikiro Semuenzaniso, yb: yg, iyo inoburitsa chiedza pa1030nm, inogona kuoneka seyakaenzana-matatu-mwero-scems kuimba tembiricha, asi ina-level system na77k. Er: Zvimwe chetezvo ndezvechokwadi kuti Yag.

Zvichienderana nepfuma svikiro, kukura kwemamwe maitiro ekutsvuka anozoderedzwa.

Yakasanganiswa nezvinhu zviri pamusoro, kushanda kwakadzika kwekushisa kunogona kugadzirisa zvakanyanya kuita kweiyo laser. Kunyanya, kudziya kwakadzika kutonhora lasers kunogona kuwana simba rakanyanya rekubuda pasina inokanganisa, ndiko kuti, kunaka kwehunhu hwakanaka kunogona kuwanikwa.

Imwe nyaya yekufunga ndeyekuti mune yakacheneswa laser Crystal, iyo mwenje wakadururwa uchaderedzwa, saka iyo wavelength tuning renji ichave yakatsiga, uye mutsara wezana uye wavelength uye wavelength uye wavelength uye wavelength Nekudaro, mhedzisiro iyi kazhinji haiwanzoitika.

Cryogenic Kutonhora Kazhinji inoshandisa inotonhorera, yakadai seyechivhi nitrogen kana yemvura helium, uye zvine musoro kuti firtofgether inotenderera kuburikidza nehuku yakabatanidzwa kune laser crystal. Inotonhorera yakadzoreredzwa munguva kana kudzoreredzwa mune yakavharwa loop. Kuti udzivise kusimbisa, zvinowanzo kuve zvakafanira kuisa iyo laser crystal mune yekuvhara imba.

Pfungwa yeLaser makristasi anoshanda pakudziya akaderera anogona zvakare kuiswa kune mashlifiers. Titanium safhire inogona kushandiswa kuita zvakanaka mhinduro amplifier, iyo avhareji yekubuda simba mumakumi ematsi.

Kunyangwe cryogenic inotonhorera midziyo inogona kuomesaLaser Systems.
