I-AgGaS2 — Amakristalu we-Optical Infrared Angaqondile Isithombe Esifakiwe

I-AgGaS2 - Amakristalu e-Optical Infrared angaqondile

Incazelo emfushane:

I-AGS isobala ukusuka ku-0.53 ukuya ku-12 µm.Nakuba i-coefficient yayo ye-optical nonlinear iphansi kakhulu phakathi kwamakristalu e-infrared ashiwo, ukuhlelwa kwe-wavelength emfushane okubonisa ngale ku-550 nm kusetshenziswa kuma-OPO ampontshwa yi-Nd:YAG laser;emihlolweni eminingi yokuhlanganisa imvamisa yomehluko nge-diode, i-Ti:Sapphire, Nd:YAG namalaser kadayi we-IR amboza ububanzi obungu-3–12 µm;kumasistimu okumelana ne-infrared aqondile, kanye ne-SHG ye-CO2 laser.

Incazelo Yomkhiqizo

Amapuleti ekristalu e-Thin AgGaS2 (AGS) adumile ekukhiqizeni i-ultrashort pulse ebangeni elimaphakathi le-IR ngomehluko wokukhiqiza imvamisa esebenzisa i-NIR wavelength pulses.

Izinhlelo zokusebenza

● Isizukulwane sesibili se-harmonics ku-CO ne-CO2 - amalaser
● I-oscilator ye-Optical parametric
● Ijeneretha yefrikhwensi eyahlukene ukuya ezindaweni ezimaphakathi ne-infrared kufika ku-12 mkm.
● Ukuhlanganisa imvamisa endaweni ye-IR emaphakathi ukusuka ku-4.0 ukuya ku-18.3 µm
● Ama-laser wesimo esiqinile ashunwayo (i-OPO ifunwe ngu-Nd:YAG namanye ama-lasers asebenza endaweni engu-1200 kuya ku-10000 nm asebenza kahle 0.1 kuya ku-10 %)
● Izihlungi zebhendi emincane ezibonayo endaweni eseduze nephoyinti le-isotropic (0.4974 m ku-300 °K), ibhendi yokudlulisela ishunwa ekushintsheni kwezinga lokushisa.
● Ukuguqulwa okuphezulu kwesithombe semisebe ye-laser ye-CO2 sibe eduze ne-IR noma isifunda esibonakalayo ngokusebenzisa/noma ukusetshenziswa kwe-Nd:YAG, i-ruby noma amalaser odayi asebenza kahle kufika ku-30 %

Izici

● Ukudluliselwa ngo-0.25-5.0 mm, akukho ukumuncwa ku-2-3 mm
● High conductivity ezishisayo
● Inkomba ephezulu ye-refraction kanye ne-Non-birefringence
