AgGaS2 - kristal anya infrared na-adịghị adị
Nkọwa ngwaahịa
Mkpa kristal AgGaS2 (AGS) kristal bụ ewu ewu maka ultrashort pulse ọgbọ n'etiti IR nso site iche ugboro ọgbọ na-eji NIR wavelength pulses.
Ngwa
● Ọgbọ nke abụọ harmonics na CO na CO2 - lasers
● Oscilator parametric oscilator
● Igwe ọkụ ọkụ dị iche iche na mpaghara infrared etiti ruo 12 mkm.
● Ngwakọta ugboro ugboro na mpaghara etiti IR site na 4.0 ruo 18.3 µm
● Tuneable solid state lasers (OPO pumped by Nd:YAG na lasers ndị ọzọ na-arụ ọrụ na mpaghara 1200 ruo 10000 nm na arụmọrụ 0.1 ruo 10%).
● Ihe nzacha eriri anya dị warara na mpaghara dị nso ebe isotropic (0.4974 m na 300 °K), a na-emegharị eriri nnyefe na mgbanwe okpomọkụ.
● Ntugharị elu nke CO2 laser radieshon image n'ime nso-IR ma ọ bụ a na-ahụ anya mpaghara site na iji/ma ọ bụ iji Nd:YAG, ruby ma ọ bụ ihe eji esiji lasers na-arụ ọrụ ruo 30 %
Atụmatụ
● Nbufe na 0.25-5.0 mm, ọ dịghị absorption na 2-3 mm
● High thermal conductivity
● Ngosipụta dị elu nke ntụgharị uche na enweghị isi
