Imvamisa yokuphindaphindeka kane kwe-Fiber Ultraviolet Laser Isithombe Esifakiwe

I-Frequency Fiber Ultraviolet Laser ephindwe kane

Imodeli: EFL-FHG-XX-YY-ZZ¹

Incazelo emfushane:

Iqembu le-Erbium linikeza amandla aphezulu, amalaser e-UV ashintshwayo enziwa imvamisa eyodwa ukusuka ku-250 kuye ku-400 nm, ukuze asetshenziswe kusayensi ye-quantum efana nama-athomu abandayo, ama-athomu abandayo kakhulu, injabulo ye-photon eyodwa ye-athomu yase-Rydberg nezinga lemvamisa.Ilaser ye-UV itholakala ngokuhlanganisa i-all-fiber amplifier efakwe ne-ultra-narrow linewidth laser, iyunithi yokuphinda kabili imvamisa ye-single-pass enekristalu ye-PPLN kanye ne-cascaded resonant cavity.Lawa ma-laser anezici zobubanzi bomugqa obuncane, i-polarization yomugqa kanye nokuguquleka.Ngemva kokulawula amandla asebenzayo, amandla okukhipha i-RMS e-laser angaphansi kuka-1.0% phakathi namahora angu-3.

Ipharamitha Yezobuchwepheshe

Omaka bomkhiqizo

Izici Eziyinhloko

● Isakhiwo esilula sokuphindaphinda imvamisa yephasi eyodwa

● Ukusebenza kahle okuphezulu kwangaphandle kwe-cavity resonance frequency kabili

● Amandla okukhipha aphezulu

● umsindo ophansi kakhulu

● ububanzi bomugqa obuncane

Izinhlelo zokusebenza

● I-photon eyodwa ye-Rydberg excitation ye-Rubidium atom (297 nm)

● Ukupholisa i-Beryllium ion (313 nm)

● Ukubhala ngokusanhlamvu (390 nm)

● Iwashi le-calcium ion optical (397 nm)

● Ukupholisa i-athomu ye-Ytterbium (399 nm)

Amalaser angu-1050nm kanye ne-1550nm anobubanzi bomugqa obuncane asetshenziswa njengemithombo yembewu ngokulandelanayo.Ngemva kokukhulisa nge-fibre eyodwa, ama-laser amabili akhiqiza i-laser engu-626 nm enobubanzi obuncane bomugqa namandla aphezulu esebenzisa i-crystal SFG ehlukaniswa ngezikhathi ezithile.Ngokukhipha i-resonant yangaphandle ephumelelayo

I-cavity, ubude begagasi be-laser buguqulwa bube yibhande le-ultraviolet ku-313 nm.Uma kuqhathaniswa nokukhishwa kwemigodi emibili ezwakalayo ene-diode laser kanye ne-tapered amplifier, umkhiqizo wethu unokwakheka okuminyene futhi okuzinzile, amandla amakhulu okukhipha i-laser.
