AgGaS2 - Makristalo a Infrared Opanda Linear Owonetsedwa

AgGaS2 - Makhiristo Opanda Owoneka Opanda Mzere

Kufotokozera Kwachidule:

AGS imawonekera kuchokera ku 0.53 mpaka 12 µm.Ngakhale kuti coefficient yake ya kuwala kopanda mzere ndi yotsika kwambiri pakati pa makhiristo a infuraredi omwe atchulidwa, mawonekedwe owoneka bwino afupikitsa pa 550 nm amagwiritsidwa ntchito mu OPO omwe amapopedwa ndi Nd:YAG laser;pamitundu yosiyanasiyana yoyesera yosakanikirana ndi diode, Ti:Sapphire, Nd:YAG ndi ma laser amtundu wa IR omwe amaphimba 3-12 µm osiyanasiyana;m'makina achindunji a infrared countermeasure system, ndi SHG ya CO2 laser.

Mafotokozedwe Akatundu

Ma mbale akristalo a Thin AgGaS2 (AGS) ndiwodziwika kwambiri pakupanga ma ultrashort pulse m'katikati mwa IR ndi kusiyana kwa ma frequency omwe amagwiritsa ntchito ma pulses a NIR wavelength.

Mapulogalamu

● Generation second harmonics pa CO ndi CO2 - lasers
● Optical parametric oscilator
● Jenereta yosiyana siyana kumadera apakati a infuraredi mpaka 12 mkm.
● Kusakaniza pafupipafupi m'chigawo chapakati cha IR kuchokera ku 4.0 mpaka 18.3 µm
● Ma lasers olimba (OPO amapopedwa ndi Nd:YAG ndi ma lasers ena omwe amagwira ntchito ku 1200 mpaka 10000 nm dera ndi 0.1 mpaka 10%)
● Zosefera zowoneka bwino za bandi yopapatiza kudera pafupi ndi isotropic point (0.4974 m pa 300 °K), bandi yotumizira imawunikiridwa pakusinthasintha kwa kutentha.
● Kusintha kwapamwamba kwa chithunzi cha kuwala kwa laser cha CO2 kukhala pafupi ndi IR kapena dera lowonekera pogwiritsa ntchito/kapena kugwiritsa ntchito Nd:YAG, ruby kapena utoto lasers mogwira mtima mpaka 30%

Mawonekedwe

● Kutumiza mu 0.25-5.0 mm, palibe kuyamwa mu 2-3 mm
● High matenthedwe madutsidwe
● Mlozera wapamwamba wa refraction ndi Non-birefringence
