Sehlopha sa Machaena se thehile Raman e nang le matla a phahameng a 1.2μmlaser ea fiber

Lisebelisoa tsa lasere sebetsang sehlopheng sa 1.2μm e na le lisebelisoa tse ikhethang tsa phekolo ea photodynamic, tlhahlobo ea biomedical, le sensing oxygen. Ho feta moo, li ka sebelisoa e le mehloli ea pompo bakeng sa tlhahiso ea parametric ea mabone a mahareng a infrared le bakeng sa ho hlahisa leseli le bonahalang ka makhetlo a mabeli. Li-laser tsa sehlopha sa 1.2 μm li fihletsoe ka mefuta e fapanengli-laser tse tiileng, ho kenyeletsalisebelisoa tsa laser tsa semiconductor, lisebelisoa tsa laser tsa diamond Raman, le li-laser tsa fiber. Har'a li-lasers tsena tse tharo, fiber laser e na le melemo ea sebopeho se bonolo, boleng bo botle ba borali le ts'ebetso e tenyetsehang, e etsang hore e be khetho e ntle ka ho fetisisa ea ho hlahisa 1.2μm band laser.
Haufinyane tjena, sehlopha sa lipatlisiso se etelletsoeng pele ke Moprofesa Pu Zhou oa Chaena se thahasella li-lasers tsa fiber tse matla a phahameng sehlopheng sa 1.2μm. Fiber e phahameng ea hona joalelisebelisoa tsa laserhaholo-holo ke ytterbium-doped fiber lasers sehlopheng sa 1 μm, 'me matla a mangata a hlahisoang sehlopheng sa 1.2 μm a lekanyelitsoe ho boemo ba 10 W.
