GaSe Crystal

ʻO Gallium Selenide (GaSe) non-linear optical single crystal, e hui pū ana i kahi coefficient non-linear nui, kahi paepae pōʻino kiʻekiʻe a me kahi ākea ākea ākea.He mea kūpono loa ʻo GaSe no SHG ma waena o IR.DIEN TECHhāʻawi i ka kristal GaSe me ka nui nui a me ke ʻano kiʻekiʻe.

Ua aʻo ʻia nā waiwai palua pinepine o GaSe ma ka lōʻihi o ka nalu ma waena o 6.0 µm a me 12.0 µm.Ua hoʻohana maikaʻi ʻia ʻo GaSe no ka SHG kūpono o ka laser CO2 (a hiki i ka 9% hoʻololi);no ka SHG o pulsed CO, CO2 a me kemika DF-laser (l = 2.36 µm) radiation;ka hoʻohuli ʻana o CO a me CO2 laser radiation i loko o ka laulā ʻike ʻia;hana ʻia nā puʻupuʻu infrared ma o ka hoʻohui pinepine ʻana o Neodymium a me ka laser dye infrared a i ʻole (F-)-center laser pulses;Hoʻokumu māmā OPG i loko o 3.5–18 µm;terahertz (T-kukui) hana hoʻoheheʻe.ʻAʻole hiki ke ʻoki i nā kristal no kekahi mau ʻāpana like ʻole ma muli o ke ʻano o ka mea (e hoʻokaʻawale i ka mokulele (001)) e kaupalena ana i nā wahi o nā noi.
ʻO GaSe kahi aniani palupalu loa a me ka papa.No ka hana ʻana i ke aniani me ka mānoanoa kikoʻī, lawe mākou i ka mānoanoa e hoʻomaka ana i ka blank, No ka laʻana, 1-2 mm mānoanoa a laila hoʻomaka e wehe i ka papa ma ka papa e hoʻāʻo ana e hoʻokokoke i ka mānoanoa kauoha ʻoiai e mālama ana i ka maʻalahi o ka ʻili a me ka palahalaha.Eia nō naʻe, no ka mānoanoa e pili ana i ka 0.2-0.3 mm a i ʻole ka liʻiliʻi o ka pā GaSe e kūlou maʻalahi a loaʻa iā mākou ka ʻili curved ma kahi o kahi pālahalaha.
No laila mākou e noho maʻamau ma 0.2 mm mānoanoa no 10x10 mm aniani i kau ʻia i loko o ka dia.1 '' paʻa me CA wehe ʻana.9-9.5 mm.
I kekahi manawa, ʻae mākou i nā kauoha no nā kristal 0.1 mm, akā naʻe, ʻaʻole mākou e hōʻoia i ka palahalaha maikaʻi no nā kristal lahilahi.
Nā noi o nā kristal GaSe:
• THz (T-rays) hoʻoulaulaula;
• Laulā THz:0.1-4 THz；
• SHG kūpono o CO 2 laser (hiki i ka 9% hoʻololi);
• No ka SHG o pulsed CO, CO2 a me DF-laser kemika (l = 2.36 mkm) radiation;
• Ka hoʻohuli ʻana o CO a me CO2 laser radiation i ka laulā ʻike ʻia;hana ʻia nā puʻupuʻu infrared ma o ka hoʻohui pinepine ʻana o Neodymium a me ka laser dye infrared a i ʻole (F-)-center laser pulses;
• OPG hana kukui i loko o 3.5 - 18 mkm.
SHG i ka waena-IR (CO2, CO, kemika DF-laser etc.)
ka hoʻohuli ʻana o ka IR laser radiation i loko o ka laulā ʻike ʻia
Hanana parametric i loko o 3 – 20 µm
