Ubushakashatsi Bushya kurilaser ifite ubugari bw'umurongo muto

Laser ifite ubugari bw'umurongo muto ni ingenzi mu bikorwa bitandukanye nko kumenya neza, spectroscopy, na siyansi ya quantum. Uretse ubugari bwa spectral, imiterere ya spectral nayo ni ingenzi, biterwa n'uburyo ikoreshwa. Urugero, imbaraga ku mpande zombi z'umurongo wa laser zishobora guteza amakosa mu gukoresha neza qubits no kugira ingaruka ku buryo amasaha ya atome ateye. Ku bijyanye n'urusaku rw'umuvuduko wa laser, ibice bya Fourier bivangwa n'imirasire yinjira mulaserUburyo busanzwe buri hejuru ya 105 Hz, kandi ibi bice bigena ubwinshi bw'umuvuduko ku mpande zombi z'umurongo. Hamwe na Henry enhancement factor n'ibindi bintu, hagenwa quantum limit, ari yo Schawlow-Townes (ST). Nyuma yo gukuraho urusaku rwa tekiniki nko guhindagurika kw'ibice n'uburebure, iyi quantum limit igena uburebure bw'umuvuduko bushoboka. Kubwibyo, kugabanya urusaku rwa quantum ni intambwe y'ingenzi mu gushushanyalaser z'ubugari bw'umurongo muto.

Mu minsi ishize, abashakashatsi bavumbuye ikoranabuhanga rishya rishobora kugabanya ubugari bw'imirasire ya laser inshuro zirenga ibihumbi icumi. Ubu bushakashatsi bushobora guhindura burundu urwego rwa quantum computing, amasaha ya atome na gravitational wave detection. Itsinda ry'abashakashatsi ryakoresheje ihame ryo gukwirakwiza Raman kugira ngo rifashe lasers gukurura vibrations nyinshi mu bikoresho. Ingaruka zo kugabanya ubugari bw'imirasire inshuro ibihumbi ziruta iz'uburyo gakondo. Mu by'ukuri, ni kimwe no gutanga ikoranabuhanga rishya ryo gusukura spectral ya laser rishobora gukoreshwa ku bwoko butandukanye bwa lasers zinjiye. Ibi bigaragaza iterambere ry'ibanze mu rwego rwaikoranabuhanga rya laser.

Ubu buryo bushya bwakemuye ikibazo cy’impinduka z’igihe cy’urumuri rw’amajwi mu buryo butunguranye bituma ubuziranenge n’ubunyangamugayo bw’imirasire ya laser bigabanuka. Muri laser nziza, imiraba yose y’urumuri igomba guhuzwa neza - ariko mu by’ukuri, imiraba imwe y’urumuri iba iri imbere gato y’indi cyangwa inyuma yayo, bigatuma habaho ihindagurika mu cyiciro cy’urumuri. Uku guhinduka kw’ibyiciro bitanga "urusaku" muri spectrum ya laser - bigabanya ubwinshi bw’ibara rya laser kandi bigabanya ubuziranenge bw’amabara yayo. Ihame ry’ikoranabuhanga rya Raman ni uko iyo uhinduye uku kutumvikana kw’igihe mu mihindagurikire muri kristale ya diyama, uku gutembera kw’amajwi kwinjirwa vuba no gushonga (mu gihe cya triliyoni nke z’isegonda). Ibi bituma imiraba y’urumuri isigaye igira imihindagurikire yoroshye, bityo igera ku buziranenge bwo hejuru bw’imirasire kandi igatanga ingaruka zikomeye kuspectrum ya laser.
