Yintoni i-crygegenic lar

Umxholo we-lasers osebenza kumaqondo obushushu asezantsi ayisiyonto intsha: I-laser yesibini kwimbalini yayiyi-Filygenic. Ekuqaleni, ingcinga yayinzima ukufezekisa ukusebenza kobushushu begumbi, kwaye inzondelelo yomsebenzi wobushushu ophantsi waqala ngo-1990s ngokuphuhliswa kweendlela eziphezulu ze-AMPER kunye ne-Amplifiers.

Kumandla aphezuluImithombo yase-laser, Iziphumo ze-Sermal ezinje ngelahleko yokulahleka, iilensi ze-thermal okanye i-laser crystal bell zinokuchaphazela ukusebenza kweUmthombo wokukhanya. Ngokungaphantsi kweqondo lobushushu elipholileyo, iziphumo ezininzi ezinobungozi zinokucinezelwa ngempumelelo, oko kukuthi, i-PROPIUM kufuneka ipholiselwe ukuya kwi-77k okanye i-4K. Iziphumo zokupholisa ikakhulu zibandakanya:

Ukuqhutywa kwenqanaba lokufumana impumelelo kunqatshelwe kakhulu, ubukhulu becala kuba i-INDAWO YOKUGQIBELA YENKQUBO YENKONZO YENZA. Ngenxa yoko, iqondo lobushushu le-graps lehla ngendlela engathethekiyo. Umzekelo, xa amaqondo obushushu athotyelwa ukusuka kwi-300k ukuya kwi-77K, ukuqhubela kwe-thermal yekristali ye-Yag yonyuswa sisixhenxe.

Ukuhlutha komntu okrwada kuyancipha. Oku, kunye nokuncitshiswa kweqondo lobushushu, iziphumo kwifuthe elinciphile i-thermal ye-thermal kwaye ke kukuncitshiswa kokuqhelaniswa koxinzelelo.

Ukusebenza kwe-thermo-optical kuncitshisiwe, kuncitshiswe ngakumbi isiphumo se-thermal lens.

Ukunyuswa kwecandelo le-adsurmer proult ye-ion enqabileyo ye-ion ikakhulu ngenxa yokwehla kokusasazwa okubangelwa yimpembelelo yerhulank. Ke ngoko, amandla ocwangco incitshisiwe kwaye inzuzo ye-lasendle iyanda. Ke ngoko, umbungu wempompo wempompo uncitshisiwe, kwaye iipulses ezifutshane zinokufumaneka xa i-Q Swiption isebenza. Ngokwandisa ukuhanjiswa kwesibini esitshatileyo, ithambo elisebenza kakuhle linokuphuculwa, ngoko ke imeko yelahleko ye-parasitic ayibalulekanga.

Inqaku lecandelo elipheleleyo lenqanaba eliphantsi le-quasi-3ine-nqanaba eliphakathi lincitshisiwe, ngoko ke amandla empompo encitshiswayo ancitshiswa kwaye ukusebenzela amandla kuyaphucuka. Umzekelo, yb: YAG, evelisa ukukhanya nge-1030NM, inokubonwa njengenkqubo ye-quasi-33 kwiqondo lobushushu legumbi, kodwa i-77k. I-ER: Kuyafana nakwi-Yag.

Kuxhomekeka kwi-Pine Primea, ubukhulu beenkqubo ezithile zokungena ziya kuncitshiswa.

Zidityaniswe nezi zinto zilapha ngasentla, ukusebenza kobushushu obuphantsi kunokuphucula kakhulu ukusebenza kwe-laser. Ngokukodwa, iqondo lobushushu eliphantsi lokupholisa i-lars linokufumana amandla aphezulu okuphumeza ngaphandle kwefuthe le-Thermal, oko kukuthi, umgangatho olungileyo we-beam unokufunyanwa.

Omnye umbandela wokuqwalaselwa kukuba kwi-crystal ye-laser, i-bandwidth yokukhanya okuqaqambileyo kunye nokukhanya komgangatho kuya kuncitshiswa, kwaye ilayini yobubanzi buya kuba yingqongqo ye-pumped evuthayo. Nangona kunjalo, le mpembelelo ihlala inqabile.

I-Crygenagenc yokuphola ihlala isebenzisa ipholont, njenge-nitrogen yolwelo okanye i-helium engamawele, kwaye i-herementi yefriji ejikelezayo nge-tube eqhotyoshelwe kwi-tytal eqhotyoshelwe kwikristali yase-laser. Ukuphola kuyagcwaliswa kwakhona ngexesha okanye ukuphinda kusetyenziswe kwakhona kwilog evaliweyo. Ukwenzela ukuthintela ukuqina, ihlala iyimfuneko ukubeka i-laser cystal kwigumbi lokuphumla.

Umxholo wekristali yase-laser esebenza kumaqondo obushushu asezantsi anokusetyenziswa kwi-Amplifiers. I-Titanium Sappphire inokusetyenziselwa ukwenza ingxelo eyakhayo ye-Amplifier, i-APREPUP YOKUGQIBELA IXESHA LOKUGQIBELA KWE-TALS.

Nangona izixhobo zokupholisa i-Cryogenic zinokuhlanganisaIinkqubo ze-laser, iinkqubo eziqhelekileyo zokupholisa zihlala zilula, kwaye ukusebenza kakuhle kokupholisa i-Cryogenic kuvumela ukuncipha kobunzima.
