Nd: Iikristale ze-YAG
Nd: Intonga ye-crystal ye-YAG isetyenziswe kumatshini wokumakisha i-Laser kunye nezinye izixhobo ze-laser.
Kuphela kwezinto eziqinileyo ezinokusebenza ngokuqhubekayo kwiqondo lobushushu begumbi, kwaye yeyona kristale yelaser igqwesileyo.
Kwakhona, i-YAG (i-yttrium aluminium garnet) i-laser inokufakwa nge-chromium kunye ne-neodymium ukwenzela ukunyusa iimpawu zokufunxa kwe-laser.I-Nd, i-Cr: i-LAG ye-laser yi-laser yesimo esiqinileyo. ibhantiifunxa amandla kwaye iwadlulisele kwi-ion ye-neodymium (Nd3 +) ngendlela ye-dipole-dipole interactions.Ubude be-wavelength be-1064nm bukhutshwa yile laser.
Isenzo se-laser ye-Nd: YAG laser yaboniswa okokuqala kwiiLebhu zeBell ngonyaka ka-1964. I-Nd, Cr: YAG laser impontshwa ngemitha yelanga. Ngokusebenzisa i-chromium, amandla okufunxa amandla e-laser ayaphuculwa kwaye iipulses ezimfutshane kakhulu ziyakhutshwa.
