Tokiso ka hare ho 2.5–12 µm e fumanwe ha o pompa ka laser Ho:YLF ka 2.05 µm; hammoho le ts'ebetso ea ho bapisa mekhahlelo e seng ea bohlokoa (NCPM) ka hare ho 1.9–5.5 µm ha e pompa ka 1.4–1.55 µm. AgGaSe2 (AgGaSe) e bonts'itsoe e le kristale e sebetsang habeli habeli bakeng sa mahlaseli a infrared CO2 lasers.
Ka ho sebetsa hammoho le li-synchronously-pumped oscillators parametric oscillators (SPOPOs) tse fumanehang khoebong pusong ea femtosecond le picosecond, likristale tsa AgGaSe2 li bontšitse hore li sebetsa ka mokhoa o sa tsitsang oa parametric downconversion (phapang frequency generation, DGF) sebakeng sa Mid-IR. kristale ea AgGaSe2 ea bohareng ba IR e na le e 'ngoe ea lipalo tse kholo ka ho fetisisa tsa boleng (70 pm2/V2) har'a likristale tse fumanehang khoebong, tse fetang tse lekanang le AGS ka makhetlo a tšeletseng. AgGaSe2 e boetse e ratoa ho likristale tse ling tsa bohareng ba IR ka mabaka a 'maloa a ikhethileng. Mohlala, AgGaSe2, e na le sebaka se tlase sa ho tsamaea 'me ha e fumanehe habonolo bakeng sa ho alafshoa bakeng sa lits'ebetso tse ikhethileng (mohlala, mokhoa oa ho hola le oa ho seha), leha e na le sebaka se seholo sa ho se kopane le sebaka se lekanang le pepeneneng.
