Tom qab ib xyoos ntawm kev ua haujlwm hnyav, peb tau loj hlobCrystal iavnrog zoo heev ua tiav.
Peb lub tshuab muaj peev xwm muab tauGaSeCrystal nrog loj aperture thiab nyias thickness.
Gallium Selenide (GaSe) non-linear optical ib leeg siv lead ua, sib txuas ua ke loj uas tsis yog-linear coefficient, muaj kev puas tsuaj loj thiab ntau qhov pom tseeb.Nws yog ib qho khoom siv zoo heev rau SHG hauv nruab nrab IR.Qhov zaus-doubling zog ntawmGaSetau kawm nyob rau hauv lub wavelength ntawm 6.0 µm thiab 12.0 µm.GaSetau ntse siv rau SHG zoo ntawm CO2 laser (txog 9% hloov dua siab tshiab);rau SHG ntawm pulsed CO, CO2 thiab tshuaj DF-laser (l = 2.36 µm) hluav taws xob;upconversion ntawm CO thiab CO2 laser hluav taws xob mus rau qhov pom ntau yam;infrared pulses tiam ntawm qhov sib txawv zaus sib xyaw ntawm Neodymium thiab infrared dye laser lossis (F-)-centre laser pulses;OPG lub teeb tsim nyob rau hauv 3.5-18 µm;terahertz (T-rays) hluav taws xob tiam.Nws yog tsis yooj yim sua kom txiav cov crystals rau qee lub sij hawm sib piv cov ces kaum vim cov khoom siv (cleave raws (001) dav hlau) txwv qhov chaw ntawm daim ntawv thov.
