DIEN TECH nyedhiyakake kristal AgGaSe2 (AGSe) duwe pinggiran pita ing 0,73 lan 18 µm.Rentang transmisi sing migunani (0.9–16 µm) lan kemampuan pencocokan fase sing amba nyedhiyakake potensial sing apik kanggo aplikasi OPO nalika dipompa dening macem-macem laser sing beda.
Penyetelan kristal AgGaSe2 (AGSe) sajrone 2.5–12 µm wis dipikolehi nalika dipompa nganggo laser Ho:YLF ing 2.05 µm;uga operasi pencocokan fase non-kritis (NCPM) ing 1.9-5.5 µm nalika pompa ing 1.4-1.55 µm.
Kristal AgGaSe2 (AGSe) wis dituduhake minangka kristal dobel frekuensi sing efisien kanggo radiasi laser CO2 inframerah.
Aplikasi AGSe:
• Generasi harmonik kapindho ing CO lan CO2 - laser
• osilator parametrik optik
• generator frekuensi beda kanggo wilayah infra merah tengah nganti 18 um.
• Frekuensi nyawiji ing wilayah IR tengah
Bagean salib standar yaiku 8x 8mm, 5 x 5mm, dawa kristal saka 1 nganti 30 mm.Ukuran khusus uga kasedhiya ing panyuwunan.
