Tsvagiridzo Itsva palaser yakamanikana ine upamhi hwemutsara
Laser ine upamhi hwemutsara mutete yakakosha mumabasa akasiyana-siyana akadai sekuona kwakarurama, spectroscopy, uye sainzi yequantum. Kuwedzera pahupamhi hwespectral, chimiro chespectral chinhu chakakoshawo, zvinoenderana nemamiriro ekushandiswa. Semuenzaniso, simba riri kumativi ese emutsara welaser rinogona kukonzera zvikanganiso mukushandiswa kwe optical kwequbits uye kukanganisa kururama kweatomu wachi. Panyaya yeruzha rwefrequency yelaser, zvikamu zveFourier zvinogadzirwa nemwaranzi inongoerekana yapinda mulaserMaitiro acho anowanzo pfuura 105 Hz, uye zvikamu izvi zvinosarudza amplitudes kumativi ese emutsetse. Kubatanidza Henry enhancement factor nezvimwe zvinhu, muganho we quantum, kureva muganho weSchawlow-Townes (ST), unotsanangurwa. Mushure mekubvisa ruzha rwehunyanzvi rwakadai se cavity vibration uye length drift, muganho uyu unosarudza muganho wakaderera wehupamhi hwemutsara hunoshanda. Nokudaro, kuderedza ruzha rwe quantum idanho guru mukugadzirwa kwelasers dzakatetepa-dzakafara.
Munguva pfupi yapfuura, vaongorori vakagadzira tekinoroji itsva inogona kuderedza upamhi hwemitsara yelaser nekanopfuura zviuru gumi. Tsvagiridzo iyi inogona kushandura zvizere minda ye quantum computing, maatomu ewachi uye kuona mafungu egiravhiti. Chikwata chekutsvagisa chakashandisa musimboti wekupararira kweRaman kwakakurudzirwa kuti malaser agone kukurudzira vibrations yepamusoro-soro mukati mechinhu chacho. Mhedzisiro yekupfupisa upamhi hwemutsara yakapetwa kazviuru kupfuura nzira dzechinyakare. Chaizvoizvo, zvakafanana nekupa tekinoroji itsva yekuchenesa laser spectral inogona kushandiswa kune mhando dzakasiyana dzemalaser ekuisa. Izvi zvinomiririra budiriro huru mumunda wetekinoroji yelaser.
Tekinoroji itsva iyi yakagadzirisa dambudziko rekuchinja kwenguva kwemafungu echiedza zvishoma nezvishoma izvo zvinoita kuti kuchena uye kururama kwemwaranzi yelaser kuderere. Mune laser yakakodzera, mafungu ese echiedza anofanira kurongeka zvakakwana - asi muchokwadi, mamwe mafungu echiedza ari pamberi zvishoma kana kumashure kwemamwe, zvichikonzera kuchinja-chinja muchikamu chechiedza. Kuchinja-chinja uku kwechikamu kunogadzira "ruzha" mulaser spectrum - kunodzima frequency yelaser uye kunoderedza kuchena kwayo kwemavara. Nheyo yetekinoroji yeRaman ndeyekuti nekushandura kusarongeka uku kwepanguva kuita vibrations mukati me diamond crystal, vibrations idzi dzinokurumidza kunyudzwa uye kunyangarika (mukati me trillionths shoma dzesekondi). Izvi zvinoita kuti mafungu echiedza asara ave ne oscillations dzakapfava, nokudaro achiwana kuchena kwakanyanya kwe spectral uye achigadzira mhedzisiro yakakosha palaser spectrum.
