Chikwata cheChinese chakagadzira 1.2μm bhendi yakakwira-simba tunable ramanfiber laser

Laser zvinyorwaKushanda mu1,2μm bhendi ine zvimwe zvakasarudzika zvekushandisa muTemdynamic Therapy, Biomicial Diagnostics, uye oksijeni kunzwa. Mukuwedzera, ivo vanogona kushandiswa sedanda reparamende yerudzi rwechiyero chepakati-infrered mwenje uye nekugadzira mwenje unooneka nemufambiro wekupedzisira. Lasers mu1,2 μm band yakawanikwa zvakasiyanaSolid-State Lasers, kusanganisirasemiconductor lasers, Dhaimani Ramani Lasers, uye Fiber Lasers. Pakati peaya matatu lasers, Fiber Laser ane zvakanakira chimiro chakareruka, yakanaka yemhando yemhando uye inochinjika kushanda, iyo inoiita sarudzo yakanakisa yekugadzira 1.2μm bhendi laser.
Nguva pfupi yadarika, timu yekutsvagisa yakatungamira naProfessor pu zhou muChina inofarira yakakwira-simba fiber lasers mune 1.2μm bhendi. Iyo yazvino yakakwirira simba fiberlasersvanonyanya kuve yeYtterbium-Didter Fiber Lasers mune 1 μm Band mu1,2 basa raizotevera raman fiber pa1,2μM yekudzoraOptoelectronics.

Pfungwa ndeye kushandisa iyo yakakurudzirwa Raman inopararira mhedzisiro mune inopfuura fiber yekugadzira yakakwira-simba laser mu1,2μm bhendi. Yakakurudzirwa Raman kuparadzira ndeye chechitatu-kurongeka nonlinear mhedzisiro inoshandura mafoto kusvika kureba wavelengths.
