Ubushakashatsi bushya kuriUmuyoboro muto

Laser-linewidth laser ningirakamaro muburyo butandukanye bwo gukoresha nko kumva neza, spekitroscopi, na siyanse ya siyanse. Usibye ubugari bwikigereranyo, imiterere yikigereranyo nayo ni ikintu cyingenzi, biterwa nibisabwa. Kurugero, imbaraga kumpande zombi zumurongo wa laser zishobora kuzana amakosa muburyo bwiza bwo gukoresha qubits kandi bikagira ingaruka kumasaha ya atome. Kubijyanye n urusaku rwa laser yumurongo, ibice bya Fourier biterwa nimirasire yizana yinjira murilaseruburyo busanzwe burenga 105 Hz, kandi ibyo bice bigena amplitude kumpande zombi zumurongo. Ugereranije ibintu byongera Henry hamwe nibindi bintu, ingano ya kwant, aribyo imipaka ya Schawlow-Townes (ST). Nyuma yo gukuraho urusaku rwa tekiniki nko kunyeganyega kwa cavity hamwe nuburebure bwa drift, iyi mipaka igena imipaka yo hasi yubugari bugaragara. Kubwibyo, kugabanya urusaku rwa kwantani nintambwe yingenzi mugushushanyaInzira-ndende.

Vuba aha, abashakashatsi bakoze ubuhanga bushya bushobora kugabanya umurongo wa lazeri inshuro zirenga ibihumbi icumi. Ubu bushakashatsi bushobora guhindura rwose imirima ya comptabilite, amasaha ya atome hamwe na gravitational wave detection. Itsinda ry’ubushakashatsi ryakoresheje ihame ryo gutatanya Raman gutatanya kugirango lazeri zishimishe umuvuduko ukabije wibikoresho. Ingaruka zo kugabanya umurongo wikubye inshuro ibihumbi kurenza uburyo bwa gakondo. Byibanze, bihwanye no gutanga tekinoroji nshya ya laser yo kweza ishobora gukoreshwa muburyo butandukanye bwo kwinjiza lazeri. Ibi byerekana intambwe yibanze murwego rwatekinoroji ya laser.

Ubu buhanga bushya bwakemuye ikibazo cyumunota utunguranye wumucyo wigihe cyigihe gitera ubwiza nukuri kwibiti bya laser kugabanuka. Muri lazeri nziza, imiraba yumucyo yose igomba guhuzwa neza - ariko mubyukuri, imiraba imwe yumucyo iri imbere gato cyangwa inyuma yizindi, bigatera ihindagurika mugice cyumucyo. Ihindagurika ryicyiciro ribyara "urusaku" murwego rwa laser - bihindura inshuro ya laser kandi bigabanya ibara ryera. Ihame rya tekinoroji ya Raman ni uko muguhindura ibyo bidakwiye byigihe gito mukuzunguruka muri kristu ya diyama, ibyo kunyeganyega byinjira vuba kandi bigatandukana (muri tiriyari nke zisegonda). Ibi bituma imiraba yumucyo isigaye ifite ihindagurika ryoroshye, bityo ukagera kumurongo wera kandi ukabyara ingaruka zikomeye kurilaser.
