Chikwata cheChinese chakagadzira 1.2μm bhendi yepamusoro-simba tunable Ramanfiber laser

Laser zvinyorwainoshanda mubhendi ye1.2μm ine zvimwe zvakasarudzika mukurapa kwephotodynamic, biomedical diagnostics, uye kunzwa oxygen. Pamusoro pezvo, anogona kushandiswa sepombi masosi ekugadzirwa kweparametric yepakati-infrared mwenje uye kugadzira mwenje unooneka nekupeta kaviri. Lasers mu 1.2 μm bhendi yakave yakawanikwa zvakasiyanasolid-state lasers, kusanganisirasemiconductor lasers, diamondi Raman lasers, uye fiber lasers. Pakati peaya matatu lasers, fiber laser ine zvakanakira chimiro chakareruka, yakanaka danda mhando uye inoshanduka kushanda, izvo zvinoita kuti ive sarudzo yakanakisa kugadzira 1.2μm bhendi laser.
Munguva pfupi yapfuura, timu yekutsvagisa inotungamirwa naProfessor Pu Zhou kuChina inofarira yakakwirira-simba fiber lasers mubhendi re1.2μm. Ikozvino high power fiberlaserskunyanya ytterbium-doped fiber lasers mu 1 μm band, uye simba guru rinobuda mu 1.2 μm bhendi rinogumira kusvika pamwero we 10 W. Basa ravo, rine musoro unoti "High power tunable Raman fiber laser pa 1.2μm waveband," yaiva rakabudiswa muFrontiers ofOptoelectronics.

Pfungwa ndeye kushandisa yakasimudzwa yeRaman yekuparadzira maitiro mune passive fiber kugadzira yakakwirira-simba laser mu1.2μm bhendi. Yakasimudzwa Raman kuparadzira ndeyechitatu-odha isina mutsara mhedzisiro inoshandura mafotoni kune akareba wavelengths.

Vatsvakurudzi vakashandisa yakakurudzirwa Raman kuparadzira maitiro mu phosphorus-doped fiber kushandura high-simba ytterbium-doped fiber pa 1 μm band kusvika 1.2 μm bhendi. Chiratidzo cheRaman chine simba rinosvika 735.8 W chakawanikwa pa1252.7 nm, inova simba repamusoro rekubuda re1.2 μm band fiber laser yakataurwa kusvika parizvino.

Mufananidzo 3: (a) Yakanyanya kuburitsa simba uye yakajairwa kubuda spectrum pane akasiyana masaini wavelengths. (b) Yakazara yakabuda spectrum pane akasiyana masign wavelengths, mu dB (Δλ inoreva 3 dB mutsara).
