Ikipe y'Ubushinwa yateje imbere 1.2μm zitsinda-imbaraga zo kuringaniza raman fibre fibre

Ikipe y'Ubushinwa yateje imbere 1.2μm band-imbaraga zingana na ramanfibre laser

Amasoko ya LaserGukorera mu itsinda rya 1.2μm bifite porogaramu zidasanzwe muri tekinike, uburemere busanzwe, na ogisijeni. Mubyongeyeho, barashobora gukoreshwa nka pompe yamasoko kubisekuru bya parametric bikaba umucyo watewe no kubyara urumuri rugaragara ukoresheje inshuro nyinshi. Lasers muri 1.2 μm band yagezeho hamwe nibitandukanyelaser-leta, harimoSemiconductor lasers, raman raman arahari, na fibre laser. Muri aba baturage batatu, fibre laser ifite ibyiza byoroheje, ubwiza bwiza bwimiterere nubucuruzi bworoshye, bituma arihitamo neza kubyara 1.2μm band laser.
Vuba aha, itsinda ry'abashakashatsi ryayobowe na Porofeseri Pu Zhou mu Bushinwa rishishikajwe na fibre nyinshi za fibre zitsinda 1.2μm. Amashanyarazi maremarelasersAri ahanini EDbium-dosiye ya fibre muri 1 μm itsinda ryabatsinda rya 1.2 μmOpTtoelectronics.

Igishushanyo 1:. PDF: Fibre ya Phososhorus; QBH: Quarz igice kinini; WDM: Igice cyuburebure rusange; Sfs: Superfluorescent Cober Inkomoko; P1: Port 1; P2: Port 2. P3: Erekana icyambu cya 3. Inkomoko: zhang yang et al., Imbaraga nyinshi zibangamiye Raman fibre fibre fibre, 2024).
Igitekerezo nugukoresha ingaruka ziterwa na raman ishidikanye muri fibre ya pasiporo kugirango itange umusingi wo hejuru mumatsinda 1.2μm. Gutesha agaciro Raman Gukwirakwiza ni gahunda ya gatatu idahwitse ihindura gufotora kugeza uburebure burebure.

Igishushanyo 2: Guhuza ibintu bisanzwe rfl ibisohoka kuri (a) 1065-1074 nm na (b) 1077 nm pomp yubatse (Δλ yerekeza kuri 3 db umurongo). Inkomoko: Zhang Yang et al., Imbaraga nyinshi zibangamiye Raman fibre kuri 1.2μm Waveband, imipaka ya Optoelectronics (2024).
Abashakashatsi bakoresheje ingaruka za Raman itesha agaciro muri fibre ya phosoforus yo guhindura imikino myinshi ya Ytterbium yo hejuru kuri 1 μm band kugeza 1.2 μm band. Ikimenyetso cya Ramani gifite imbaraga zigera kuri 735.8 W wabonetse kuri 1252.7 NM, aricyo imbaraga zo hejuru za 1.2 μ1 μm zitsinda rya fibre lases zavuzwe kugeza ubu.

Igishushanyo cya 3: (a) Ibisohoka byinshi bisohoka hamwe nibisohoka bisanzwe kumurongo bitandukanye wamaguru. . Inkomoko: Zhang Yang et al., Imbaraga nyinshi zibangamiye Raman fibre kuri 1.2μm Waveband, imipaka ya Optoelectronics (2024).

Igicapo: 4: (a) spectrum na (b) imiterere yihindagurika iranga imbaraga zisumba izindi za raman fibre fibre fiblifier amplifier amplifier amplifier amplifier amplifier amplifier amplifier ampleing uburebure bwa 1074 Nm.
