AgGaS2 - Likristale tsa infrared tsa Optical Nonlinear
Tlhaloso ea Sehlahisoa
Lipoleiti tsa kristale tsa Thin AgGaS2 (AGS) li tumme bakeng sa tlhahiso ea ultrashort pulse bohareng ba IR ka mefuta e fapaneng ea tlhahiso ea maqhubu e sebelisang maqhubu a maqhubu a NIR.
Lisebelisoa
● Li-harmonics tsa bobeli tsa moloko ho CO le CO2 - lasers
● Optical parametric oscilator
● Jenereithara e fapaneng ea maqhubu ho ea libakeng tse bohareng tsa infrared ho fihlela ho 12 mkm.
● Ho kopanya khafetsa sebakeng se bohareng sa IR ho tloha ho 4.0 ho isa ho 18.3 µm
● Li-laser tsa boemo bo tiileng tse Tuneable (OPO e pompetsoe ke Nd:YAG le lilase tse ling tse sebetsang sebakeng sa 1200 ho isa ho 10000 nm ka katleho ea 0.1 ho isa ho 10%)
● Lisefe tsa Optical narrow-band sebakeng se haufi le isotropic point (0.4974 m at 300 °K), transmission band e ntse e totobatsoa ha mocheso o fetoha.
● Phetoho e phahameng ea setšoantšo sa mahlaseli a laser CO2 hore e be haufi le IR kapa sebakeng se bonahalang ka ho sebelisa/kapa ho sebelisa Nd:YAG, ruby kapa dae lasers ka bokhoni ba ho fihla ho 30%
Likaroloana
● Phetiso ka 0.25-5.0 limilimithara, ha ho monya ka 2-3 limilimithara
● High mogote conductivity
● High index of refraction le Non-birefringence
