IiCrystals ze-AgGaSe2 - iBand Edges Kwi-0.73 kunye ne-18 µm
Ingcaciso yeMveliso
I-Tuning ngaphakathi kwe-2.5–12 µm ifunyenwe xa ukumpompelwa nge-laser ye-Ho:YLF kwi-2.05 µm; ngokunjalo nokusebenza kwesigaba esingabalulekanga (NCPM) ngaphakathi kwe-1.9–5.5 µm xa umpompa nge-1.4–1.55 µm. I-AgGaSe2 (i-AgGaSe) ibonakaliswe njengeyona ndlela isebenzayo yokuphinda-phinda ikristale yemitha ye-infrared ye-CO2 lasers.
Ngokusebenza ngokudibeneyo kunye ne-synchronously-pumped oscillators oscillators optical (SPOPOs) kwi-femtosecond kunye ne-picosecond, i-crystals ye-AgGaSe2 ibonise ukuba iyasebenza kwi-nonlinear parametric downconversion (i-difference frequency generation, i-DGF) kummandla we-Mid-IR. Ikristale ephakathi kwe-IR engahambelaniyo ye-AgGaSe2 inelinye lawona manani makhulu okugqwesa (70 pm2/V2) phakathi kweekristale ezifikelelekayo kurhwebo, eliphindwe kathandathu kunokulingana kwe-AGS. I-AgGaSe2 ikwakhetheka kwezinye iikristale ezisembindini we-IR ngenani lezizathu ezithile. I-AgGaSe2, umzekelo, inohambo olusezantsi lwesithuba kwaye ayifumaneki lula ukuba inyangwe kwizicelo ezithile (ukukhula kunye nesalathiso esisikiweyo, umzekelo), nangona inomda omkhulu wokungahambelani kunye nommandla olinganayo ocacileyo.
Usetyenziso
● Isizukulwana sesibini se-harmonics kwi-CO kunye ne-CO2 - iilaser
