Gase Crystal

Gallium Selenide (GaSe) otu kristal anya na-abụghị linear, na-ejikọta ọnụ ọgụgụ buru ibu na-abụghị nke linear, ọnụ ụzọ mmebi dị elu na oke nghọta.GaSe bụ ihe dabara adaba maka SHG n'etiti IR.Ụlọ ọrụ DIN TECHnye kristal GaSe nwere nnukwu nha pụrụ iche na ịdị elu dị elu.

A mụrụ ihe eji eme GaSe ugboro abụọ n'ogo ogologo n'etiti 6.0 µm na 12.0 µm.Ejirila GaSe nke ọma maka SHG nke CO2 laser nke ọma (ruo ngbanwe 9%);maka SHG nke pulsed CO, CO2 na chemical DF-laser (l = 2.36 µm) radieshon;mgbanwe nke CO na CO2 laser radieshon n'ime ihe a na-ahụ anya;Ọgbọ infrared site na ngwakọta ugboro ugboro nke Neodymium na laser dye infrared ma ọ bụ (F-) -ụkpụrụ laser etiti;Ọgbọ ọkụ OPG n'ime 3.5-18 µm;terahertz (T-ray) ọgbọ radieshon.Ọ bụ ihe na-agaghị ekwe omume igbutu kristal maka akụkụ ụfọdụ dabara na akụkụ n'ihi nhazi ihe (cleave along (001) ụgbọelu) na-amachi mpaghara ngwa.
GaSe dị nnọọ nro na kristal oyi akwa.Maka mmepụta nke kristal nwere ọkpụrụkpụ akọwapụtara, anyị na-amalite oghere oghere, dịka ọmụmaatụ, 1-2 mm gbara ọkpụrụkpụ wee malite iwepu oyi akwa site na oyi akwa na-anwa ịbịaru nso n'iwu ka ọ na-edobe ịdị mma na ịdị larịị.Otú ọ dị, maka ọkpụrụkpụ ihe dị ka 0.2-0.3 mm ma ọ bụ obere efere GaSe na-ehulata ngwa ngwa ma anyị na-enweta elu elu kama ịbụ nke dị larịị.
Ya mere, anyị na-anọkarị na 0.2 mm ọkpụrụkpụ maka 10x10 mm crystal mounted in dia.1 '' njide na CA oghere dia.9-9.5 mm.
Mgbe ụfọdụ, anyị na-anabata iwu maka kristal 0.1 mm, Otú ọ dị, anyị anaghị ekwe nkwa dị mma flatness maka otú mkpa kristal.
Ngwa nke kristal GaSe:
• THz (T-ray) ọgbọ radieshon;
Ogologo THz: 0.1-4 THZ;
• SHG dị mma nke laser CO 2 (ruo ngbanwe 9%);
• Maka SHG nke pulsed CO, CO2 na chemical DF-laser (l = 2.36 mkm) radieshon;
• Ngbanwe nke CO na CO2 laser radieshon n'ime ihe a na-ahụ anya;Ọgbọ infrared site na ngwakọta ugboro ugboro nke Neodymium na laser dye infrared ma ọ bụ (F-) -ụkpụrụ laser etiti;
• Ọgbọ ọkụ OPG n'ime 3.5 - 18 mkm.
SHG na etiti IR (CO2, CO, chemical DF-laser wdg)
