AgGaS2 — Na Crystal Infrared Optical Nonlinear
Hōʻike huahana
He mea kaulana nā pā aniani AgGaS2 (AGS) no ka hoʻokumu ʻana i ka pulse ultrashort ma waena o ka laulā IR ma o ka ʻokoʻa ʻokoʻa o ka hoʻohana ʻana i nā pulu nalu NIR.
Nā noi
● Generation lua harmonics ma CO a me CO2 - lasers
● Optical parametric oscilator
● ʻOkoʻa alapine generator i waena infrared māhele a hiki i 12 mkm.
● ʻO ka hui pinepine ʻana ma ka ʻāpana IR waena mai 4.0 a 18.3 µm
● Nā laser mokuʻāina paʻa hiki ke hoʻokō ʻia (OPO i puhi ʻia e Nd:YAG a me nā lasers ʻē aʻe e hana ana ma 1200 a 10000 nm ʻāina me ka maikaʻi 0.1 a 10 %)
● ʻO nā kānana ʻāiki ʻokiʻoki ma ka ʻāina kokoke i ka lae isotropic (0.4974 m ma 300 °K), hoʻokani ʻia ke kāʻei hoʻouna ma ke ʻano wela.
● Ka hoʻololi ʻana o ke kiʻi hoʻoheheʻe laser CO2 i loko o kahi kokoke-IR a i ʻole ʻāpana ʻike ʻia ma o ka hoʻohana ʻana/a i ʻole ka hoʻohana ʻana i nā lasers Nd:YAG, ruby a i ʻole dye me ka maikaʻi a hiki i 30 %
Nā hiʻohiʻona
● Hoʻouna i ka 0.25-5.0 mm, ʻaʻohe absorption ma 2-3 mm
● High thermal conductivity
● Kiʻekiʻe index o refraction a me ka non-birefringence
