Itumanaho rya Quantum: lazeri yoroheje

Itumanaho rya Quantum:indangantego

Umuyoboro mutoni ubwoko bwa lazeri ifite imiterere yihariye ya optique, irangwa nubushobozi bwo gukora urumuri rwa lazeri hamwe na optique ya optique (ni ukuvuga ibintu bito). Ubugari bwumurongo wa lazeri ntoya yerekana ubugari bwurwego rwarwo, ubusanzwe bugaragarira mu muyoboro mugari wa unité, kandi ubu bugari buzwi kandi nka "ubugari bwumurongo" cyangwa "ubugari bwumurongo". Imirongo migari ya lisiti ifite ubugari bwumurongo muto, mubisanzwe hagati ya kilohertz magana (kHz) na megahertz nkeya (MHz), ni ntoya cyane ugereranije nubugari bwumurongo wa lazeri zisanzwe.

Gutondekanya ukurikije imiterere:

1. Umurongo wa cavity fibre lazeri igabanijwe muburyo bwagabanijwe bwa Bragg (DBR Laser) kandi bwatanzwe muburyo bwo gutanga ibitekerezo (DFB Laser) inzego ebyiri. Ibisohoka lazeri byombi ni urumuri ruhuza cyane hamwe n'umurongo muto hamwe n'urusaku ruke. DFB fibre laser irashobora kugera kubitekerezo byombi kandilaseruburyo bwo gutoranya, ibisohoka rero laser frequency stabilite nibyiza, kandi biroroshye kubona uburyo buhoraho bwo gusohora ibintu birebire.

2. Nyamara, kubera uburebure burebure bwa cavity, intera ndende ya intera ndende ni nto, kandi biroroshye gusimbuka uburyo munsi y’ibidukikije, kandi ituze rirakennye.

Gusaba ibicuruzwa:

1 Kurugero, mukibazo cyumuvuduko cyangwa ubushyuhe bwa fibre optique, guhagarara kwumurongo muto wa laserwidth bifasha kumenya neza ibisubizo byapimwe.

. Muguhitamo iburyo bwumurongo nuburebure bwumurongo, lazeri yagutse irashobora gukoreshwa muburyo bwo gusesengura neza no gupima ibintu. Kurugero, mubyuma bya gaze no gukurikirana ibidukikije, lazeri ntoya irashobora gukoreshwa kugirango igere ku bipimo nyabyo byo kwinjiza optique, ibyuka bihumanya hamwe na molekile ya spekure mu kirere.

3. Ukoresheje umurongo umwe ufunganye umurongo wa fibre laser nkisoko yumucyo utanga urumuri, uhujwe na optique coherence detection, irashobora kubaka intera ndende (kilometero amagana) liDAR cyangwa intera. Iri hame rifite ihame ryakazi nki tekinoroji ya OFDR muri fibre optique, ntabwo rero ifite imiterere ihanitse cyane, ariko kandi irashobora kongera intera yo gupima. Muri iyi sisitemu, uburebure bwa laser bwerekana umurongo cyangwa uburebure bwa coherence bigena intera yo gupima intera no gupima neza, bityo rero uko guhuza kwiza kwumucyo, niko imikorere ya sisitemu yose.
